EXECUTIVE SUMMARY
The primary goal of the survey reported in this document is to provide estimates of the
fishable biomass of principal demersal, small pelagic and mesopelagic fish species off the
Arabian Sea coast of Oman for ongoing stock assessment of Omani fisheries, to guide
development and investment decisions.
The area surveyed included the territorial waters and EEZ of the Sultanate of Oman
between Ra’s Al Hadd and the Oman-Yemen border between depths of 20 m and 250 m. In
addition, survey activities for mesopelagic resources and exploratory sampling on the
continental slope extended to deeper waters up to 100 nm offshore
Five seasonal surveys with an average duration of 47 days were completed in the project
period using the RV Al Mustaqila 1. The surveys were timed to ensure coverage of the main
seasons, with an overlap of one season, between August 2007 and September 2008.
During the 5 surveys we completed a total of 238 days at sea. A total of 442 tonnes of fish
and invertebrates were caught, 213,363 fish and invertebrates were measured, 99,319 fish
had biological data collected from them, 445 fish and shark species or species groups were
recorded. Of these 91 are possible new records for Oman. 110 non-fish species or species
groups of invertebrates, including cuttlefish, squids and benthic invertebrates were also
recorded
Demersal fish survey
Each of the five surveys was completed successfully Overall station densities ranged
between 1:259 (stations per km2) and 1:213 from all five surveys. The location of
untrawlable areas determined from these surveys was similar to those detailed in the
Rastrelliger survey report. Overall, however, the proportion of the survey area defined as
untrawlable on the Al Mustaqila 1 surveys (21%) was less than for the Fridjof Nansen and
Rastrelliger surveys (39%).
Highest densities of demersal species were recorded in the shallower stratum (20-50 m) in
Zone B on surveys 2, 3 and 5, with a maximum of 167,500 kg per square km.
Comparatively low densities occurred on all surveys in the deeper strata, 100 to 250 m, in
Zone C. There were significant changes in the seasonal distribution of many of the key
species, particularly movement from inshore to deeper water.
Distribution of spawning fish by sex, zone, and by survey for the key species was analysed.
There were clear indications of distinct seasonal spawning times for some species. Median
length at maturity (L50) ogives for eighteen of twenty key species were estimated using
logistic regression.
In the absence of age composition data, we examined the length frequency distribution data
from the survey to evaluate the possibility of deriving information on year class strengths
and recruitment variability. For most of the key species there was no useful information
available on the likely levels of recruitment variability owing, in general, to the inability to
define distinct year classes in the distributions
Biomass for target species was estimated by the swept area method. Biomass estimates
from the trawl survey were calculated using wingspread as the area swept. Spawning stock
biomass was estimated for the key demersal species by utilising estimates of size at 50%
maturity where adequate information on gonad stages was available.
Total survey biomass was estimated from each survey for all demersal fish and shark
species combined, by stratum and zone. Total biomass estimates within the survey strata are
based on the full size range of each species sampled by the trawl. Estimates range from
233,000 t on survey 5 to 420,000 t on survey 3. Zone B had the highest estimates of
biomass on 3 of the surveys, while Zone C estimates were highest on Surveys 1 and 4. The
20–50 m depth range generally held the highest biomass for Zones A and B, while the 50–
100 m depth range generally produced the highest biomass for Zone C and Zone D.
Total biomass was estimated for key species in trawlable and untrawlable areas. Surveys 1
and 5 in the post SW monsoon period recorded the highest biomass estimates for 3 of the
key 22 species. Low oxygen conditions during that season limited the distribution of the
larger fish species in Zones A, B and C to shallow water. Highest biomass estimates came
from surveys 2, 3 and 4 as species ranged into deeper water, with survey 3 having the
highest estimates for 8 of the key species, survey 2, 6 species and survey 4, 5 species.
Estimated spawning stock biomass and coefficients of variation were calculated for 18 of the
22 key species by survey where estimates of median size at maturity were available
Any comparisons of the estimates of biomass of demersal resources between the
Rastrelliger and Al Mustaqila surveys should be treated with caution. The survey designs
are not strictly comparable as the Rastrelliger surveys were designed as a combined
acoustic-trawl survey with a systematic sampling scheme chosen to maximise the overall
sampling effort. Trawl stations were not preselected on a random basis but carried out
whenever possible in terms of suitable grounds. The analysis from the Rastrelliger survey
used all surveys combined although there are attempts to break this down seasonally. The
Al Mustaqila 1 survey voyages have been analysed separately and show significant
variation in demersal fish distribution and abundance between surveys. Little information is
available from the earlier surveys to enable comparison by species, so data for all demersal
species combined are presented.
The weighted mean catch rates were compared by demersal zone and overall between the
Rastrelliger and Al Mustaqila 1 surveys are generally similar at:
Demersal Zone

Al Mustaqila 1 kg/hr
Zone A

Zone D

The biomass estimates are not significantly different between the 1989/90 and 2007/8
surveys. The total estimates from the Rastrelliger surveys are lower on surveys 1, 2 and 5
compared with the Al Mustaqila 1 surveys. Estimates for Zones A, B and C fall below and
above the Rastelliger surveys while there are much higher estimates from Zone D from 4 of
the 5 Al Mustaqila 1 surveys, although the c.v.s on these are high.
Small Pelagic Resources Survey
Acoustic marks were identified based on the percentage of species catch weight as a
proportion of the total catch in mark identification trawls. There were up to 25 successful
mark identification trawls on each of the 16 mark categories identified. A total of 201
species were caught in mark identification trawls. To reduce the complexity of the
computations, these 201 species were grouped into 25 groups, based upon their relative
abundance and their taxonomy and morphology. The mean target strengths of each group
were estimated from published target-strength relationships for analogous species and
length and weight data collected during all five surveys.
The Arabian and Indian scads were the most widely distributed of the small pelagic species.
The core of the distribution was between Ra’s al Madraka and Ra’s Hasik, but they were
also found in the other strata. Scads were found in layers extending over deep water, up to
250 m bottom depth. They were also often seen in layers associated directly with the
bottom, as well as in midwater.
Sardines (Sardinella species) were found in patchy schools in shallow waters, typically less
than 40 m deep. These schools often extended from the bottom to the surface. Most of the
sardine schools were observed between Masirah Island and Ra’s al Madraka.
Clupeids (slender rainbow sardine and red-eye round herring) were also observed in dense
schools in stratum P2a. Typical aggregations were close to the surface (upper 10-15 m of
the water column) but over deeper waters than sardines. Some extensive aggregations were
observed in stratum P2b in 2008, consisting of a series of small dense surface patches or
clusters. Even in deep water (~100 m) clupeid schools were always close to the surface.
A similar surface distribution was observed with anchovies. Anchovy aggregations were,
however, not seen or identified as often as other schooling fish (sardines and other
clupeids). Like sardines, anchovies also tended to occur more in shallow waters, but not
exclusively. Particularly strong aggregations of anchovies were observed during the pre SW
Monsoon between Ra’s al Hadd and Masirah Island. Very few schools of anchovies were
identified in the following survey, with the exception of a small aggregation close to Ra’s
Hasik.
Layers with myctophids were observed within the survey area in the post SW Monsoon to
NE Monsoon surveys, with some weak layers in strata P3 and P1. More significant layers of
myctophids were only observed in the spring inter-Monsoon survey, in strata P1 and P2b.
Layers in the southern part of P2b, between Ra’s Sawqirah and Ra’s Hasik, extended all the
way to the shallow end of the depth range.
Strong layers dominated by the Oman gaper were observed during the first post SW
Monsoon survey and the NE Monsoon surveys, with layers in strata P1 and throughout P2b.
No layers of Oman gaper were observed in the repeated post SW Monsoon survey. Layers
of ridged swimming crabs extending within our survey depth were observed during the post
SW Monsoon to NE Monsoon surveys in 2007 in strata P1. Crabs were observed again in
the pre SW Monsoon survey close to Ra’s al Madraka and on the last post SW Monsoon
survey further south off Ra’s Sawqirah.
The acoustic decomposition values were used to obtain estimates of biomass of small
pelagics. Biomasses were calculated for each stratum and for the entire survey area, along
with coefficients of variation.
Scads were the most abundant of the small pelagic species, with biomass ranging from just
under 800 000 tonnes to more than 2 million tonnes. Coefficients of variation for scads
were low because of their wide distribution within the survey area. Other small pelagic
species were more patchily distributed and have relatively high coefficients of variation.
Sardines biomass estimates were quite high, reaching almost half a million tonnes during
the post SW Monsoon voyages. Coefficients of variation were lower on these two voyages
as well, suggesting a more uniform distribution.
Other clupeids biomasses were lower with a mean of about 160 000 tonnes across voyages.
Anchovies were the less common of the small pelagics schooling species, with relatively
low biomass estimates (~10 000 - 40 000 tonnes) with the exception of the pre SW
Monsoon survey, where large aggregations were identified in the north resulting in a
biomass estimate of more than 180 000 tonnes.
The combined total biomass estimates (tonnes) of all main “true” small pelagic species,
including the scads, sardines, clupeids, and anchovies was:

Comparisons of biomass estimates to those obtained from previous surveys should be done
with caution. Differences in general approach, methodology, equipment used,
computations, and conversion factors can have significant impacts on the estimates.
The Fridtjof Nansen surveys used target strength to fish length relationships that have since
been improved. Improvement in echosounder technology and calibration are also important.
For example, the 1975-76 surveys were most likely affected by measurement saturation.
Different surveys may also covers different depth strata. The Fridtjof Nansen sampled to
depth of 15 m, while the Rastrellinger and this survey did not cover areas inside 20 m.
Also, there are some differences in gears that would undoubtedly affect survey results, such
as difference in the performance and catchability of different nets on different vessels,
which in turn affect interpretation of acoustic backscatter.
Our estimates of biomass are much higher than those estimated during the Rastrellinger
survey. They estimated a total maximum standing biomass of 252,000 tonnes, comprised
mostly of Sardinella longiceps, Decapterus russelli, Trachurus indicus, and Selar
crumenophtalmus. Our estimates are more in line with the previous Fridtjof Nansen survey
(1983-84) results with scads as predominant species. Our results suggest higher biomass
than ever recorded in this area.
Mesopelagic fish survey
“Offshore” acoustic survey transects began at the continental shelf edge (at about 200 m
depth) approximately 30 minutes after sunrise or after the completion of the dawn descent.
Six transects were completed per survey. Transects extended for the distance the vessel was
able to steam during daylight hours, including time for target identification tows. Transects
ended when the mesopelagics begin their dusk ascent. Return (shorewards) transects began
after the dawn descent. 3 areas were surveyed on each offshore mesopelagic survey. Two
transect locations from each area were randomly selected. Spacing between transects was at
least 1.5 nautical miles.
“Nearshore” survey transects began at the 200 m contour and extended up to 5 nautical.
miles offshore. They ran approximately perpendicular to the coastline. 4 areas were
surveyed and transects from each area were randomly selected with spacing between
transects of at least 1.5 nautical miles. 6 transects were completed in Area 1, 4 in Area 2, 2
in Area 3 and 6 in Area 4.
Twenty-three midwater mesopelagic target identification tows were completed on
OMA0801, 18 on OMA0802 and 17 on OMA0803. The three surveys captured a total of 88
different species/species groups. In total, nearly 6 t. of myctophids and 1.5 t. of ‘other’
species were caught.
The Ra’s al Hadd area, regardless of time of year, had the highest catches. In general,
species diversity increased from Ra’s al Hadd to the Oman-Yemen border. After the NE
monsoon diversity increased with distance offshore for most areas. After the SW monsoon
period, diversity increased with distance offshore only off Ra’s al Hadd and near the OmanYemen border.
Myctophid densities were highest near the shelf edge on all surveys. For the offshore
surveys, myctophid density, once past the shelf edge, was fairly consistent and relatively
high with distance from shore in the Ra’s al Hadd area. This trend was found in all areas
surveyed immediately after the NE monsoon period. After the SW monsoon, myctophid
density was high in the southern two strata only at the shelf edge.
Other mesopelagic species groups had high densities in the area off Ra’s al Hadd for most
seasons surveyed. Squids, swimming crabs and jellyfish tended to be most dense
throughout the survey area immediately following the SW monsoon period. Highest
densities of swimbladdered, deep-sea fish and shrimps were measured after the NE
monsoon .
After the NE Monsoon (Feb-Mar) average densities were moderately consistent across each
of the offshore areas surveyed, averaging around 19 t km–2. During the pre SW monsoon
period (Apr-Jun) densities in the nearshore areas off Ra’s al Hadd had increased
dramatically (to 155 t km–2). Densities in the other nearshore areas surveyed remained low
(< 4 t km–2 ). After the SW monsoon (Aug–Sept) densities were still very high in Stratum 1
(at 72 t km–2) but had dropped to low levels in the other offshore strata (< 2 t km–2 )
Total myctophid biomass was highest immediately after the SW monsoon period off Ra’s al
Hadd. Biomass estimates were approximately 1.2  106 t, however, confidence intervals
were extremely high (+/- 1.1  106 t) due to high sampling variance. Myctophid biomass
was generally highest in the area off Ra’s al Hadd during all periods surveyed. This is not
surprising as this is an area of high productivity throughout much of the year. In this area
biomass was highest during the spring intermonsoon period. This is most likely a lagged
effect of the extremely high productivity caused by upwelling during the NE monsoon in
the Gulf of Oman and north of Massirah Island.
Estimates from 2007–08 are of a similar order to estimates by the Rastrelliger (1989–90),
but much lower than estimates by the Fridtjof Nansen (1975–76). Al Mustaqila I biomass
estimates are from an area intermediate in size between the Fridtjof Nansen (which covered
the entire Arabian Sea coast of Oman) and Rastrelliger surveys. Some biases were apparent
in the early Fridtjof Nansen surveys and were most likely due to inadequate acoustic
identification and sampling; the high biomass estimates were questioned and concluded to
be dubious.
Estimates from the Rastrelliger survey were only from the area off Ra’s al Hadd. The
reported estimate was averaged from two time periods, immediately after the SW monsoon
(August) and the autumn intermonsoon period (November), making comparisons difficult.
Biomass estimates from 2007–08 from the Ra’s al Hadd area immediately after the SW
monsoon period were approximately 2.5 times higher. However, after averaging all periods
in a manner similar to the Rastrelliger report, biomass estimates in the Ra’s al Hadd area in
2007–08 were within the confidence interval of the Rastrelliger 1990 estimate.
Exploratory Survey on Upper Continental Slope
Opportunities for exploratory trawls were sought, when the vessel was carrying out other
survey activities, by monitoring of acoustic data collected while the ship was underway.
Information was also made available from recent commercial fishing trawls conducted in the
250-1000m depth range from the survey vessel (Al Mustaqila 1).
At each potential site the ship first surveyed with echosounder equipment to determine
whether the bottom was suitable for trawling and if there were any acoustic marks indicating
the presence of fishable resources. Tows were carried out using the standard survey trawl (or
midwater trawl as appropriate) with the trawl on the bottom for 1.5 to 2.0 nautical miles at a
speed of approximately 3 knots.
Attempts to find trawlable ground on the continental slope off survey Zone A were limited
to one small area. The rest of the zone was too rough or steep to successfully deploy the
trawl. The slope in Zones B and C had good areas of trawlable ground although the
northern part of Zone B and the southern sector of Zone C were too steep and rough to trawl
on. Demersal zone D in depths greater than 250 m had very steep and untrawlable ground to
the north and south of the area, with a section in the middle, off Salalah, having good
trawlable ground. The maximum depth fished was 843 metres.
The southern stratum appeared much more promising with good catches, although mainly
of species attaining a small size. The largest single catch from all trawl stations was 15,197
kg taken on OMA0802 station 501 during an exploratory trawl in the southern stratum.
Catches of Arabian whip lobsters (Puerulus sewelli) in this area showed promising signs of
a potential commercial fishery. The trawl gear used is not particularly effective at catching
this species as the groundrope is too high to effectively sample them, so dentieies estimated
here are like;y to be conservative. Small specimens of alfonsino (Beryx splendens), a
commercially important species, were also taken.
Six trawls were completed on the northern part of the Murray Ridge. Catches were very
small. One feature on the Murray Ridge was the quantity and variety of rubbish caught. A
second ridge to the south was surveyed but due to the rough nature of the seafloor no trawls
were attempted.

INTRODUCTION
1.1 BACKGROUND
A primary aim of the Sultanate of Oman Ministry of Fisheries Wealth (MFW) is to ensure
that fisheries are developed and managed for the advantage of the people of Oman in a
manner that is sustainable and maintains biodiversity. Surveys of the type reported in this
series of reports are part of a process that allows for development and management of
Oman’s fisheries resources in a way that is consistent with the Code of Conduct for
Responsible Fisheries.
Fisheries in Oman are complex with a wide range of species being taken by a wide range of
methods. Catches by traditional and industrial fleets are summarised in statistics published
by the MFW (Anon 2006). Total estimated landings in 2005 were 157,322 metric tonnes,
made up of 24,710 mt attributed to “industrial” fishing and 132,612 attributed to
“traditional” fishing. The catch consisted of 45,221 mt of large pelagics, 48,729 mt of small
pelagics, 40,698 mt of demersal fish, 5,630 mt of sharks and rays and 12,500 mt of
invertebrates (including lobsters and abalone).
Surveys of demersal, small pelagic and mesopelagic fish were conducted between 1963 and
1990. The most extensive of these were from RV Dr Fridtjof Nansen (Norwegian Agency
for International Development and FAO, 1975, 1976, 1983-84) (Kesteven et al 1980,
Stromme 1986) and FRV Rastrelliger (in 1989-90, UNDP 1995). Estimates of potential
yield of demersal fish in 1995 (UNDP 1995) suggested that at that time catches were close
to or exceeding potential yields. Reported demersal fish catches increased from 35,000 mt
in 1995 to over 40,000 mt in 2005. Similar conclusions were made for small pelagic fish,
although some allowance needed to be made for the significant quantities of small pelagic
fish found in shallow areas which were not surveyed. Estimated catches of small pelagics
increased from around 41,000 mt in 1995 to 49,000 mt in 2005 (Anon 2006).
A major fisheries region for Oman is the approximately 1,200 km of coast which is on the
Arabian Sea, extending from Ra’s Al Hadd in the north to the Oman-Yemen border in the
south. This area is characterised by significant shallow coastal waters, a moderate area of
continental shelf and a steep continental slope, which in the southern parts of the area is
very close to the coast. Fisheries productivity is heavily influenced by the oceanographic
dynamics in the area. This is dominated by the seasonal monsoonal winds, particularly the
Southwest monsoon, which generates upwelling of nutrient rich waters which enhances
productivity, particularly in the northern part of the area. The other major feature which is
likely to strongly influence fish productivity and distribution is the seasonal development of
an oxygen deficient layer in depths between about 50 and 1000m in which most fish species
cannot live.
The primary goal of the survey reported in this document is to provide estimates of the
fishable biomass of principal demersal, small pelagic and mesopelagic fish species off the
Arabian Sea coast of Oman for ongoing stock assessment of Omani fisheries, to guide
development and investment decisions.

The tender for the survey was awarded to New Zealand Consultant Bruce Shallard and
Associates, who enlisted the services of the New Zealand Institute of Water and
Atmospheric Research (NIWA); Deloitte New Zealand, Independent Fisheries New
Zealand, and Al Riyami Group, Sultanate of Oman.
1.2 SCOPE AND OBJECTIVES
The area surveyed included the territorial waters and EEZ of the Sultanate of Oman
between Ra’s Al Hadd and the Oman-Yemen border between depths of 20 m and 250 m. In
addition, survey activities for mesopelagic resources and exploratory sampling on the
continental slope extended to deeper waters up to 100 nm offshore, as described in detail
below.
Specific objectives as stated in the Tender Documents were:
1.
To provide good quality estimates of biomass fish of the Arabian Sea of Oman coast as
a basis for future development and for comparison with future surveys.
2.
To provide estimates of stock size, seasonal distribution and abundance for selected
target species, by using bioacoustic and survey fishing, as a basis for stock assessments
of these species.
3.
To collect pertinent biological information and samples in both traditional and
commercial fishing areas to assist in description of the biology and stock assessment of
these species.
4.
To provide information on the other species collected during the survey as a basis for
conservation of biodiversity in the Arabian Sea.
5.
To provide oceanographic information that will contribute to an understanding of the
biodiversity and ecological dynamics of the Arabian Sea and Indian Ocean, specifically
in relation to the seasonality, distribution and abundance of fishery resources.
6.
To provide spatial habitat information that will support development of spatially
related management opportunities.
7.
To explore traditional fishing grounds for less exploited but nonetheless valuable
resources.
8.
To investigate the existence of new fishing grounds, including those for benthic
resources, which might be beneficially exploited by local fisherfolk, such as marine
invertebrates and fishery resources beyond 250m depths.

200-mile limit (red line).
Five seasonal surveys with an average duration of 47 days were completed in the project
period using the RV Al Mustaqila 1. The surveys were timed to ensure coverage of the main
seasons, with an overlap of one season, between August 2007 and September 2008.
Specific timing of the surveys was designed to achieve a reasonable seasonal coverage but
to avoid the limitations on survey activity that were likely, based on normal weather
patterns, during the June-July part of the SW monsoon period. The survey design and
activities were focused on the three key resource groups specified in the Tender
Documents, demersal fish, small pelagic fish and mesopelagic fish. Survey activities were
tightly integrated within each voyage to ensure appropriate data was obtained to address the
full range of objectives.

weight), 445 fish and shark species or species groups were recorded (57 elasmobranchs and
338 teleosts). Of these 91 are possible new records for Oman. 110 non-fish species or
species groups of invertebrates, including cuttlefish, squids and benthic invertebrates were
also recorded. 3 species of turtles were caught on 10 occasions - all were released alive and
unharmed.

1.4 PERSONNEL AND EQUIPMENT
Details of all voyages and personnel are given in Appendix 1. Voyage tracks are illustrated
in Appendix 2.
Specifications for the vessel used during the survey, Al Mustaqila 1 are given in Appendix
3. The vessel is a modern commercial fishing vessel designed to operate effectively and
efficiently in a wide variety of conditions, in both inshore and deepwater fisheries. At 45.2
m long Al Mustaqila 1 is of comparable size to both the Fridtjof Nansen (49.5m length
overall) and the Rastrelliger (46.4 m). The main difference between these vessels is the
reported power, with the Al Mustaqila 1 rated at more than twice the power (3 206 hp) of
the other two vessels.
The vessel was equipped to carry out the required sampling including bottom and midwater trawling, acoustic survey using scientific echosounders, and collection of bathymetric
data and some oceanographic data. For the collection of data important to area swept trawl
surveys the ship’s trawl measuring equipment was used, including doorspread and
wingspread sensors, headline monitor (for headline height, fish marks entering the trawl
and temperature), and winch recordings of accurate warp lengths for the determination of
standard warp to depth ratios.
The primary biological data collection tool on board was an electronic “wetlab” system.
This included work stations incorporating digitizer boards pre-programmed with templates
to record length, weight and biological data electronically. Scales for recording weights
were motion compensated with ranges suitable for collection of case, individual fish and
gonad weights. The electronic data collected from the wetlab system was managed using
NIWA “trawl coordinator” software.
Navigational packages used to collect bathymetry and position data and to record tow
positions and transects included Seaplot (navigational software by way of a screen plotter)
and Piscatus, a 3 dimensional seabed mapping package.
Acoustic backscatter was recorded routinely during all survey activities, using 38kHz and
120 kHz transducers. We used a Simrad EK60 system using split-beam, hull mounted
transducers with a nominal beam angle of 7º for all frequencies. The raw acoustic data were
recorded directly to hard disk. Vessel position, speed, course, heading, pitch, and roll were
recorded in the same files as the acoustic data, ensuring synchronised sets of acoustic and
ancillary data. Position, speed, and course were obtained from the vessel’s GPS receiver,
the heading from the vessel’s gyro-compass, and pitch and roll from a separate gyrostabilised attitude sensor.
Fish traps used were of the proven metal type used in Oman waters (El-Etreby et al 2001).
The traps were 2.0 m in diameter, 1.03m high with a single opening of 0.68m x 0.56m and
mesh size 98mm.

OVERALL SURVEY IMPLEMENTATION AND PROCEDURES
To carry out the demersal fish surveys and to integrate surveys for small pelagic fish and
mesopelagic fish, we allowed for an average seasonal survey length of 47 days. Periods of
bad weather or unforseen emergencies were accommodated within this period by
appropriate adjustments to survey station densities and adjustments to the timing of voyage
elements.
The survey voyages were as follows:
Voyage 1:
OMA0701 Post SW Monsoon, 17 September 2007 to 15 October 2007
Voyage 2:
OMA0702 Post SW Monsoon to NE Monsoon, 1 November 2007 to 17
December 2007
Voyage 3:
OMA0801 Spring Inter-Monsoon, 29 January 2008 to 18 March 2008
Voyage 4:
OMA0802 Pre SW Monsoon, 19 April 2008 to 10 June 2008
Voyage 5:
OMA0803 Post SW Monsoon, 1 August 2008 to 23 September 2008
During the first part of Voyage 2 (1 Nov – 14 Nov) we completed the Post SW Monsoon
survey activities not completed on Voyage 1.
To achieve the highest quality results from trawl surveys a standardised set of procedures
for rigging and deploying the trawl gear, sampling the catch and data collection was
followed. A detailed procedures manual was developed prior to the survey and modified
following gear trials and as practical experience on the surveys developed.
1.6 DATA MANAGEMENT
All electronic data collected during the surveys were stored on a central server on the
vessel. A live backup copy of all electronic data was maintained on the vessel to reduce the
risk of data loss due to computer failure. Following extensive error checking all data were
provided to the Ministry in standard ANSI SQL statements suitable for creating and loading
data into the Ministry’s Oracle system. Raw acoustic data was provided as Simrad EK60
“raw” format files. Full documentation on the structure of all files has been provided.

2 DEMERSAL FISH SURVEY
2.1 OBJECTIVES AND METHODS
The demersal fish surveys had the following primary objectives:
-
To estimate the abundance of key commercially caught demersal fish species on the
Oman continental shelf with a target coefficient of variation of the estimate of less
than 30%.
-
To provide a base for comparison with results from trawl surveys carried out in the
area in 1975-76, 1983-84 and 1989-90.
-
To provide a high quality baseline for comparison with future surveys to monitor
these resources.
-
To collect information to allow estimation of demersal fish abundance on areas
which cannot be sampled with a bottom trawl.
-
To collect relevant oceanographic, bathymetric and habitat information, and
biological information on all species collected during the survey.
Recent fisheries research surveys in Oman that included demersal fishes have been
summarised by Garces et al (2001) and include 7 surveys from 1963 to 1983, surveys
conducted by the Fridtjof Nansen in 1983–1984 (Stromme 1986), and the Rastrelliger
surveys carried out in 1989–1990 (Johannesson 1995). The Fridtjof Nansen and
Rastrelliger surveys provided a useful base for designing a new survey series for abundance
and seasonal distribution with greater precision. In designing the Al Mustaqila 1 survey we
aimed to ensure that as far as possible there was a capability to make comparisons with
these earlier surveys (where suitably informative data were available) to enable an
evaluation of any changes in fish abundance and distribution over the last 2 decades.
5 seasonal trawl surveys of demersal fish were completed, using a stratified random survey
design, in the continental shelf area between Ra’s al Hadd and the Yemen border. Analysis
of this survey was based on the “swept area” technique.
In areas where trawls could not be used to sample demersal fish relative abundance was
evaluated using acoustic techniques, supported by the use of fish traps and underwater
video photography to identify likely species composition. Details of all methods used for
this survey are provided in Technical Report 2.
Survey area
The defined area for the survey was the continental shelf in the 20–250 m depth range from
Ra’s al Hadd to the Yemen border southwest of Salalah. The Fridtjof Nansen and
Rastrelliger surveys covered a similar depth range for demersal fish. Our ability to achieve
a good coverage of the survey area using the bottom trawl was influenced strongly by the
limitations of the available sampling techniques, and the presence of areas where vessel
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
7
access is not possible (e.g. shallow areas) or not permitted (e.g. oil and gas installations,
pipelines, marine reserves and areas of military importance). The Fridtjof Nansen surveys
reported that approximately 39% of the seabed in the survey area between 10 and 150 m
was untrawlable (Stroemme 1986). Estimates of untrawlable ground from the Rastrelliger
survey for depths between 20 and 200 m within the proposed survey area were also around
39% (Johannesson 1995). The final estimate from this project of the proportion of
untrawlable ground was 21%.
Strata and zones (dark blue) for the demersal fish survey.
Survey design
The greatest precision in surveys for mixed demersal species fisheries resources is achieved
with a two phase stratified random survey design (Francis 1981, 1984). This approach also
provided the best statistical basis for comparison with earlier surveys and minimizes the
error in biomass estimates from stratified random trawl surveys where prior information on
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary

fish distribution is limited. The allocation of trawl stations in phase 2 was based on the
catches made in phase 1.
Survey stratification
The trawl survey stratification was generally consistent with the stratification used on the
Rastrelliger surveys, although the two most southern areas (Sawqirah Bay and Kuria Muria
Bay) used by Johannesson (1995) were combined into one area (Ra’s al Madrakah to Ra’s
Hasik) for the current surveys.
The survey area was divided into 4 zones, the boundaries of which were based on features
where the shelf edge is at its narrowest, and further sub-divided by depth to make 15 strata.
As the surveys progressed we recalculated the survey area including areas of strata, based
on improving knowledge of bathymetry, ability to survey rougher ground due to improved
gear, deployment procedures, ships’ master’s fishing skills and possible changes in the area
of untrawlable seafloor since 1990 .
Where the extent of untrawlable ground in some strata resulted in insufficient area to carry
out the minimum number of trawls, particularly in the two southern Zones (C and D), we
reviewed the stratification and combined or removed some strata. Stratification was
continually reviewed throughout the surveys and the stratum boundaries were revised to
better reflect the prescribed depth ranges and exclude areas of foul ground.
Station density
The optimum number of trawl stations for a swept area trawl survey is dependent on the
inherent level of variability in fish densities in the survey area. The estimates of untrawlable
bottom given by Johannesson (1995) were used to estimate station densities. Phase 1 of
each seasonal survey consisted of 100 random trawl stations allocated to strata based on an
average station density of about 1 station per 190 square km of trawlable area, or 1 station
per 317 square km of the total area.
A minimum of three stations per stratum was sampled in phase 1 of each survey. Up to 20
phase 2 stations were then directed to the strata with the most variable catch rates of key
species. Station positions were selected randomly before each voyage with a minimum
distance between stations of 2 nautical miles. If a station was found to be on untrawlable
ground, a search for suitable ground within 2 nautical miles of the station position was
made. If no suitable ground was found, the station was abandoned and another random
position substituted. Problems arose in some areas where intensive fishing activity was
occurring and a clear trawl path could not be found among set traps and nets. In such
circumstances station positions were moved up to 2 nautical miles away to avoid conflicts,
or another random station was selected.
Trawl survey tows were carried out during daylight hours only. Care was taken to ensure
that trawls started after dawn and were completed by dusk. This approach was adopted to
minimise the effects of variations catch rates due to day/night differences in fish reactions
to the trawl, catchability and fish behaviour. Data on depth and untrawlable ground were
routinely collected on the ship’s navigational package to enable detailed maps of fishing
grounds to be created.

Target species
In consultation with the Ministry of Fisheries Wealth two species lists were developed to
guide sampling activities during the survey. The first list contained species proposed as
“key” species for the purpose of biological sampling. The second list included those species
used for the purpose of calculating the second phase stations in the trawl survey.
Species for otolith collection and detailed biological data collection: At each station,
data on length, weight, sex, gonad stage, gonad weight and otoliths were collected from
appropriate sample sizes of the species listed. All species were measured and sexed
wherever possible. Subsampling techniques were used where volumes of catch are too great
to handle effectively or the length range in the catch was very narrow. Species including
lionfishes (Pterois spp.), stonefishes, waspfishes and eel catfishes (Plotosus spp.) which
represented a potential hazard to the crew and staff. were not usually measured.

Species identification
We attempted to identify all fish and invertebrates collected to species level. The primary
fish identification guides used included Al-Abdessalaam (1995), Carpenter et al (1997),
Fischer and Bianchi (1984), and Randall (1995).
A guide was compiled made up of digital photographs and relavant taxonomic material to
aid in identification and to ensure consistency of fish identification and coding between
surveys. If it was not possible to identify any particular specimen or species at the time it
was caught photographs were taken and the specimen was retained for later identification.
A temporary species code was assigned at the time of capture and, the relevant databases
were updated later after positive identification.
Survey Equipment
The Independent 1 “mother” trawl was selected as the standard trawl for the demersal fish
surveys. This provided a good sampling tool for both large specimens and juveniles of the
key species. Two trawl nets and associated spares were available during the surveys.
The demersal trawl sampling gear used is detailed in Technical Report 2. For the collection
of data important to area swept trawl surveys we used the ship’s trawl measuring equipment
including doorspread and wingspread sensors, headline monitor for headline height, fish
marks entering the trawl and bottom temperature, and winch recordings of accurate warp
lengths for the determination of standard warp to depth ratios.
Navigational packages used to collect bathymetric bottom depth and position data and
record tow positions and transects included Seaplot (navigational software by way of a
screen plotter) and Piscatus, a 3 dimensional seabed mapping package.
Acoustic backscatter was recorded routinely during all trawl activities, using 38 kHz and
120 kHz transducers. These data enabled establishment of relationships between acoustic
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
12
backscatter and fish densities as measured by the trawl (particularly to enable estimation of
fish densities in untrawlable areas), and assisted in interpretation of fish availability to the
trawl, bathymetry, and bottom type.
Survey procedures
Standard procedures defined speed over the ground, and warp-to-depth ratios to ensure
sweeping gear angles are maintained as constant as possible between trawl stations and, in
particular, over changes in depth. We used a towing speed of 3.5 knots and a standard tow
distance of 2.0 nautical miles, and trawl rigging to achieve sweeping gear angles of less
than 20 degrees. This is consistent with the Fridtjof Nansen and the Rastrelleger surveys
where 0.5 hr tows were used. Doorspread, headline height, and vessel speed were measured
every 5 minutes during each tow and average values calculated.
Information collected at each station included:
- Catch rates.
- Size composition of all significant catch species.
- Otoliths from selected species.
- Spawning condition of selected species.
- Oceanographic data.
The catch was identified to species level where possible and weighed on motion
compensated scales. If a catch was large (over 2 tonnes) for a given species, back
calculation from processed weight was used to determine the greenweight. A random
sample of up to 200 fish of each target species per station (and of other species which were
an important component of the catch) was measured, sexed and gonad staged. A subsample
of at least 20 fish from the random sample of each species was measured, weighed, sexed,
gonad staged, and their otoliths collected. Any catch of benthos was weighed and as far as
possible identified. Representative samples were retained for identification. Digital
photographs were taken to compile a benthic fauna identification guide and thus ensure a
consistent standard between surveys.
Estimates of fish abundance on untrawlable areas
Untrawlable areas constitute a high proportion of the survey area. Information to define the
location, extent and nature of untrawlable areas was collated from a number of sources
including:
-
reports and data from the Fridtjof Nansen and Rastrelliger surveys
data and observations that were available from local commercial fishing operations
data collected acoustically during investigation of trawl survey stations
data collected acoustically during transits between stations and during acoustic
transects for the small pelagic survey.
These data were accumulated during the course of the surveys to build up a definition and
distribution of “untrawlable” areas to be used for the final calculations of abundance.
Untrawlable areas were defined primarily on a judgement by the ship’s master from
echosounder information that bottom trawl gear would be likely to be damaged.
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
13
The primary method used to estimate fish densities in untrawlable areas was estimation of
total fish backscatter on acoustic transects (including those used for the small pelagic fish
survey described below). We estimated fish density from these data by using the
relationship between fish density and acoustic backscatter on trawlable ground derived
during the trawl survey.
Partitioning of the backscatter to species was based, where possible on observations of the
species mix observed in trap catches, observations made using video cameras, and
midwater trawls (where fish marks are observed above the seafloor and there was enough
water depth to deploy the trawl). In interpreting these observations the selectivity of the
different sampling methods was carefully considered.
We also attempted to estimate fish densities over untrawlable areas by determining the
relationship between acoustic backscatter and trap catch rates. As a guide to the accuracy of
the approach, this relationship was estimated in both trawlable and untrawlable areas
Trap catch rates were measured in a standard way to minimise sources of variation in the
relationships. Traps were baited mesh bags of small pelagic fish and set during daylight
hours with the shortest possible soak time (10-12 hours) consistent with a reasonable fish
sample size. Following earlier experience gained from use of traps in an experimental
setting in Oman (Al-Masroori et al 2004) we set traps in groups of 3 in a long-line
arrangement. Traps in each group were separated from each other by a distance of
approximately 30 m.
Demersal fish survey analysis
Biomass for target species was estimated by the swept area method as described by Francis
(1981, 1989) using the formulae in Vignaux (1994). Within this estimate, the catchability
coefficient (an estimate of the proportion of fish in the path of the net which is caught) is
the product of vulnerability, vertical availability, and areal availability. These factors were
set at 1 for the biomass analysis: the key assumptions being that fish are randomly
distributed over the bottom, that no fish are present above the height of the headline, and
that all fish within the path of the trawl doors (doorspread estimates) or wingtips
(wingspread estimates) are caught.
These analyses provide estimates of relative biomass specific to the vessel, sampling gears
and trawling procedures used. Particular care must be taken in using bottom trawl survey
data to estimate absolute biomass (Hurst 1988). Absolute estimates can only be determined
from trawl surveys if the vulnerability, vertical and areal availability are known. These
three key factors will vary for each species and by fish size and are almost always poorly
estimated, hence the setting of these values as 1 (a more conservative value) in most
analyses.
Biomass estimates from the trawl survey were calculated using wingspread as the area
swept. Surveys which use the doorspread as the area swept assume that the sweeps and
bridles connecting the trawl to the trawl doors herd fish into the path of the trawl. Biomass
estimates from the Fridtjof Nansen and Rastrelliger used wingspread as the area swept.
Using biomass derived from wingspreads and not taking into account fish herded by the
trawl doors and sweeping gear may lead to an overestimation in biomass. The extent of
escapement of fish species from the trawl is unknown; escapement can occur through the
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
14
meshes of the trawl and cod-end, over the headline, and under the groundrope. Also, some
stronger swimming species are able to avoid being caught by swimming out of the trawl
during the trawling process.
Spawning stock biomass was estimated for the key demersal species by utilising estimates
of size at 50% maturity where adequate information on gonad stages was available.
Scaled length frequencies were calculated for the major species with the Trawlsurvey
Analysis Program, version 3.2 (Vignaux 1994), using length-weight data from the survey.
These were scaled to the biomass and represent the distribution of fish in the population
vulnerable to the trawl. Biomass estimates by fish size can be calculated using the length
data.

Overall station densities ranged between 1:259 (1 station per 259 km2) and 1:213 from all
five surveys for the trawlable ground.
From all five demersal surveys combined, 383.8 t of fish were caught. 155,487 fish and
squid were measured. Biological data (at least length and weight) were collected from
82,491 individuals. From the exploratory trawls, 27.6 t were caught and 5961 fish, squid
and crustaceans were measured. Biological data (at least length and weight) were collected
from 4182 individuals.
The location of untrawlable ground and of all successful demersal trawl stations from all
surveys combined are plotted in Figure 6. The position of all successful trap stations is
presented in Figure 7. The location of untrawlable areas determined from these surveys
was similar in many respects to those detailed in the Rastrelliger survey report. Overall,
however, the proportion of the survey area defined as untrawlable on the Al Mustaqila 1
surveys (21%) was less than for the Fridjof Nansen and Rastrelliger surveys (39%).

Seasonal distribution
Densities (kg per square km) of all demersal species combined, by survey are summarised
in Figure 8. Highest densities of demersal species were recorded in the shallower stratum
(20-50 m) in Zone B on surveys 2, 3 and 5, wih a maximum of 167,500 kg per square km.
Comparatively low densities occurred on all surveys in the deeper strata, 100 to 250 m, in
Zone C. Detailed information derived from the five surveys on the densities and
distribution of the key species is summarised in Technical Report 2. Distributions of
juveniles for most species were similar to the overall distribution for that species
There were significant changes in the seasonal distribution of many of the key species,
particulary movement from inshore to deeper water. The low oxygen levels recorded in the
post SW monsoon period saw catches of the key species limited to the shallowest strata.
Exceptions to this were Epinephelus diacanthus and Sepia prashadi which both appear to
be able to tolerate lower oxygen conditions and were the only large species taken regularly
in the deeper strata on surveys 1 and 5. At times during surveys 1 and 5 species expected to
be on the seafloor were observed near the surface e.g. cownose rays. Echo sounder traces
in the low oxygen areas often had clearly visible ‘barren’ zones rising above the seafloor
where there were no fish marks.
During survey 3 most species ranged further offshore into deeper water. Argyrops spinifer,
were also caught in good numbers the 150-250 m stratum on survey 4 in Zone A. This
species was only caught in the 20-50 m stratum during surveys 1 and 5 and showed
evidence of moving deeper on surveys 2 and 3. It was noted that Argyrops spinifer taken in
the 150 to 250 stratum on survey 4 were feeding heavily on swimming crabs at the time
and formed distinctive marks on the echo sounder.
Two species of catfish Arius dussumieri and Arius tenuispinis were taken almost
exclusively in the shallowest strata on each survey predominately in zones A and B.
Lethrinus microdon were distributed primarily in the northernmost part of zone A. Most of
the other key species were distributed throughout the survey area.

Distribution of spawning fish including seasonal changes
Distribution of spawning fish (stage 3 or ripe, and stage 4 or running ripe) by sex, zone,
and by survey for the key species are presented in detail by species in Technical Report 2
Appendix 6. Summaries of the numbers of fish staged by trip and the percentage of fish by
each stage for each demersal zone are also given. There were clear indications of distinct
seasonal spawning times for some species.
Arius bilineatus (Roundsnout sea catfish): Appeared to spawn in Zones A and B,
mainly during the spring inter-monsoon period (January–March). During May–June, a
relatively high proportion of spent fish were apparent, and resting or maturing fish
dominated the post SW monsoon period (August–December).
Arius dussumieri (Blacktip sea catfish): Available gonad stage data were very limited,
but it is most likely that this species spawned in Zone B just before the SW monsoon
(March–June).
Arius tenuispinis (Thinspine sea catfish): Available gonad stage data were collected
mostly during the first survey when most fish were in the resting phase. However, based on
the few data available from the third survey, it appears likely that Arius tenuispinis spawns
before the SW monsoon, as indicated for the two other Arius species.
Argyrops spinifer (King soldier bream):
Information is not clear; spent fish were
moderately abundant in the first, second and fourth surveys, yet the percentage of running
ripe females never exceeded 2% in any survey. Ripe females were most abundant in the
second and third surveys. It appears likely that the spawning season for this species could
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
20
be quite protracted, and that spawning occurs at numerous locations along the coast. The
general lack of running ripe fish is indicative of spawning occurring inshore of the survey
area. The most likely timing of the spawning season is post SW monsoon (September–
December).
Carangoides chrysophrys (Longnose jack):
Information on spawning is confusing;
spent fish or running ripe females were seldom caught in any survey. Ripe fish were
relatively common in all surveys. It appears likely that the spawning season for this species
is quite protracted, and that spawning occurs at numerous locations along the coast. There
was no obvious peak in the gonad maturation data that could be used to infer a likely
spawning season. The general lack of running ripe fish is indicative of spawning occurring
inshore of the survey area.
Carangoides malabaricus (Malabar jack):
Running ripe fish occurred almost
exclusively in Zones A and B during the second survey, but spent fish were never recorded
in any survey. Based on the relatively sparse information available, spawning is likely to
occur in the north of the survey area between about November and January.
Cheimerius nufar (Santer seabream): Running ripe fish occurred almost exclusively in
the first and last surveys, but the majority of staged fish in all surveys were juvenile or
resting. Based on the information available, spawning is likely to occur along much of the
surveyed coast after the SW monsoon (August–October).
Drepane longimana (Barred sicklefish): Spent and resting fish dominated during the
first two surveys, whereas maturing and ripe fish were most abundant in the last three
surveys. Running ripe fish were rarely recorded. The dominance of ripe fish (both males
and females) in the third and fourth surveys is indicative of a spawning season from about
March to June, at locations along the entire survey coast.
Diagramma pictum (Painted thicklip): Running ripe Diagramma pictum occurred only
in the first survey, spent fish were most common in the second survey, and the third and
fourth surveys were dominated by resting fish. Based on the information available,
spawning is likely to occur in September–October, mainly around Zone B.
Decapterus russelli (Indian scad):
Running ripe fish occurred primarily (and quite
abundantly) in the first and second surveys. Based on this information, spawning is likely
to occur after the SW monsoon (September–December), mainly around Zones B and C. It
is possible that spawning occurred slightly earlier in Zone B than Zone C.
Epinephelus diacanthus (Spinycheek grouper): The first three surveys, and the last,
were dominated by resting fish. All running ripe fish, and most of the recorded spent fish,
where caught during the fourth survey. Based on this information, the spawning season is
likely to be before the SW monsoon (May–June), and to occur predominantly around Zone
C.
Epinephelus radiatus (Obliquebanded grouper): Insufficient information is available
to infer spawning times or locations.
Lethrinus microdon (Smalltooth emperor): Although no running ripe female fish were
caught during any of the surveys, running ripe males were most abundant during the
second survey (November–December), as were spent females. It is likely that some
spawning occurs at the northern extreme of the survey area just before the NE monsoon.
Lethrinus nebulosus (Spangled emperor): Running ripe fish were caught in all surveys,
but the percentages were lowest in the second and fourth surveys. It is possible that this
species has two periods of spawning. The first immediately after the SW monsoon
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
21
(September–October), and the second during the spring inter-monsoon period (February–
March). Spawning seemed to occur predominantly in the Bay of Halaniyat and the Bay of
Masirah.
Pomadasys commersonii (Spotted grunt): Running ripe Pomadasys commersonii were
caught in all surveys, but particularly in the first, second and last surveys. About half the
fish staged in the fourth survey were spent. It is likely that this species has a prolonged
spawning season from about August through to March. Spawning seems to occur wherever
the adults are distributed, but perhaps particularly predominantly in the Bay of Masirah and
in inshore waters of the Bay of Halaniyat.
Rhizoprionodon acutus (Milk shark):
No information is available on reproductive
biology of Rhizoprionodon acutus.
Rhabdosargus sarba (Goldstriped seabream): Running ripe male fish were recorded in
all surveys, but running ripe females were caught only in the third and fourth surveys.
However, spent fish of both sexes were abundant in the second and fourth surveys.
Consequently, the reproductive cycle for Rhabdosargus sarba is very uncertain. The most
likely explanation is that they have a prolonged but sporadic spawning season from about
November to June.
Sepia pharaonis (Pharaoh cuttlefish): No information is available from these surveys
on reproductive biology of Sepia pharaonis.
Sepia prashadi (Hooded cuttlefish): No information is available from these surveys on
reproductive biology of Sepia prashadi.
Sphyraena putnamiae (Sawtooth barracuda):
No running ripe female Sphyraena
putnamiae were recorded in any survey, but running ripe males were dominant in the first
survey, and spent fish (both sexes) were clearly very abundant in the second survey.
Therefore, it appears most likely that the spawning season is probably just after the SW
monsoon (September–December).
Trachurus indicus (Arabian scad): Ripe Trachurus indicus dominated the last survey,
while running ripe fish were very abundant in the first survey. The middle three surveys
produced mainly resting and maturing stages. Therefore, it is very likely that the spawning
season is after the SW monsoon (September–October). It also appears that spawning is
more likely to occur in the north of the survey area (Zones A and B).
Trichiurus lepturus (Largehead hairtail): Running ripe male fish dominated the second
and third surveys, while running ripe females were recorded only in the third and fourth
surveys. Ripe fish of both sexes were abundant in the second to fourth surveys, but spent
fish were seldom recorded in any of the surveys. It appears likely that Trichiurus lepturus
have a protracted spawning season from perhaps December to June.
Length at maturity
Median length at maturity (L50) ogives for eighteen of twenty demersal fish species were
estimated using logistic regression; two species did not have enough data to reliably
estimate median length at maturity. Generalized linear models were fitted using a binomial
error distribution and logit link function, using data from all surveys, all areas, and both
sexes combined. Differences in maturity for males and females were ignored.

Median length at maturity could not be estimated for Rhabdosargus sarba and Sphyraena
putnamiae due to the low numbers of small, immature fish captured. Minimum and
maximum estimates of median length at maturity for most species were wide and may not
be accurate due to a paucity of data on small individuals or, for some species, a lack of data
for mature individuals. The range of estimates for Epinephelus diacanthus, Argyrops
spinifer and Cheimerius nufar, although wide, encompass the estimates found by McIlwain
et al (2005). Estimates of L50 for Lethrinus nebulosus are much larger than those found by
McIlwain et al (2005) and may be due to small sample size (n=59).
Year class strength and recruitment variability
We examined the length frequency distribution data from the survey to evaluate the
possibility of deriving information on year class strengths and recruitment variability.
Reliable estimation of year class strengths (YCSs) and levels of recruitment variability
require age data (to convert a survey length-frequency distribution into catch-at-age), and
several survey samples each one year apart (to enable comparisons of length- and agefrequency distributions in the same area and season). Available information on YCSs from
the series of surveys reported here is limited because no age data are yet available and only
two of the surveys (the first and last) are comparable in both space and time. Consequently,
comments on YCSs for any species are based only on the relative abundances of juvenile
modes in the length-frequency distributions from the first and last surveys.
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
23
It is assumed that the length and age range of a species vulnerable to the trawl is the same
in all surveys. Between-survey differences in environmental parameters and fish behaviour
could invalidate this assumption. Second, it is assumed that distinct juvenile lengthfrequency modes represent a single year class. This is uncertain without age data. Third,
the abundance of small fish in the survey catches will be strongly influenced by the trawl
mesh selectivity.
For most of the key species there was no useful information available on the likely levels
of recruitment variability owing, in general, to the inability to define distinct year classes in
the distributions, or to a lack of comparability between the first and last surveys.
Epinephelus diacanthus is the only species for which a moderately high level of
recruitment variability is indicated. For two other species (Trachurus indicus and
Trichiurus lepturus), available data tentatively suggest that recruitment variability may be
moderate to high. Some observable level of recruitment variability is indicated for
Argyrops spinifer, Carangoides chrysophrys, Cheimerius nufar, and Diagramma pictum.
Biomass of all fish and shark species combined
Total survey biomass (tonnes) and coefficents of variation (c.v.s) were estimated from each
survey for all demersal fish and shark species combined, by stratum and zone. Total
biomass estimates within the survey strata are based on the full size range of each species
sampled by the trawl.
Estimates range from 233,000 t on survey 5 to 420,000 t on survey 3. Demersal zone B
had the highest estimates of biomass on 3 of the surveys (Surveys 2, 3 and 5), while zone C
estimates were highest on Surveys 1 and 4. The 20–50 m depth range generally held the
highest biomass for demersal Zones A (3 of the 5 surveys) and B (all 5 surveys), while the
50–100 m depth range generally produced the highest biomass for Zone C (4 of the 5
surveys) and Zone D (3 of the 5 surveys).

Biomass of key species
The total biomass was taken to be the sum of the biomass on the trawlable ground and the
associated untrawlable ground area multiplied by the areal biomass density (from the
trawlable ground) and the appropriate scaling factor. C.v.s on the ratios were estimated by
bootstrapping and combined with the c.v.s from the trawl biomass to produce an overall
c.v.

Surveys 1 and 5 in the post SW monsoon period recorded the highest biomass estimates for
3 of the key 22 species. Low oxygen conditions during that season limited the distribution
of the larger fish species in demersal zones A, B and C to shallow water. Highest biomass
estimates came from surveys 2, 3 and 4 as species ranged into deeper water, with survey 3
having the highest estimates for 8 of the key species, survey 2, 6 species and survey 4, 5
species.
Spawning stock biomass estimates
Estimated spawning stock biomass (tonnes) and coefficients of variation were made for 18 of
the 22 key species by survey where estimates of median size at maturity are available.
Biomass is calculated for the trawlable area only.

Seasonal changes in biomass
Seasonal changes of biomass for key species are detailed in Technical Report 2, Appendix
6. Biomass was expected to be similar for most species for surveys OMA0701 and
OMA0803 because they were both completed during the post-SW monsoon period.
However, this was not the case. Although total biomass estimates were similar for Arius
dussumieri and Cheimerius nufar, the areas where they were captured differed between the
two surveys. C. nufar was captured in Zones A, B, and C on OMA0701; on OMA0803 it
was not captured in Zone A, but appeared in Zone D. A. dussumieri was not captured in
Zone C on OMA0701 and was captured in Zone D, but on OMA0803, the reverse
occurred.
Other notable differences included: Lethrinus nebulosus was present in Zone A on
OMA0701 but was captured only in Zones B and C on OMA0803; Carangoides
chrysophrys and Carangoides malabaricus were present throughout the survey area on
OMA0701 but were found only in Zone B on OMA0803; Diagramma pictum was found
everywhere but in Zone D on OMA0701 but was captured only in Zone B during
OMA0803; Decapterus russelli, Epinephelus diacanthus, and Epinephelus radiatus were
not in Zone D during OMA0701 but were present throughout the survey area in
OMA0803; Rhabdosargus sarba was found in Zone A during OMA0701 but was not
found there on OMA0803; and Arius bilineatus were present throughout the survey area on
OMA0701 but were captured only in Zones B and C during OMA0803.
The differences in biomass estimates between post-SW monsoon surveys may, in part, be
due to the after-effects of the cyclone that occurred in June 2007 or to the slight difference
in timing between the two surveys (the 2007 survey started 1.5 months later than in 2008).

The survey designs are not strictly comparable as the Rastrelliger surveys were designed as
a combined acoustic-trawl survey with a systematic sampling scheme chosen to maximise
the overall sampling effort. Trawl stations were not preselected on a random basis but
carried out whenever possible in terms of suitable grounds (Johannesson, 1995). The
analysis from the Rastrelliger survey used all surveys combined although there are
attempts to break this down seasonally. The Al Mustaqila 1 survey voyages have been
analysed separately and show significant variation in demersal fish distribution and
abundance between surveys. Little information is available from the earlier surveys to
enable comparison by species, so data for all demersal species combined are presented.
The adjustment for biomass over untrawlable ground done in the analysis from the
Rastrelliger assumes that most species caught on the trawl survey are more abundant over
the foul ground by a factor of 2. The Al Mustaquila survey analysis used factors based on
more detailed analysis of acoustic data but were generally in the same range. The
assumption of a gear efficiency of 0.9 in the Rastrelliger will also increase biomass
estimates relative to those from the Al Mustaqila surveys.

The biomass estimates are not significantly different between the 1989/90 and 2007/8
surveys. The total estimates from the Rastrelliger surveys are lower on surveys 1, 2 and 5
compared with the Al Mustaqila 1 surveys. Estimates for Zones A, B and C fall below and
above the Rastelliger surveys while there are much higher estimates from Zone D from 4
of the 5 Al Mustaqila 1 surveys, although the c.v.s on these are high.

There were increases in the proportion of rays, skates and guitar fishes in all zones on the
Al Mustaqila 1 surveys, although it is not clear if guitar fishes were included in totals from
the Rastrelliger work.
Sea catfishes proportions were similar in demersal zone B. Increases for grunts occurred in
most zones on the 2007/08 surveys with the main species taken in quantity being the
spotted grunt (Pomadasys commersonii). There are declines in the proportions of sea
basses in all zones, snappers in zones C and D and emperors and drums in zones A, B, and
C. The proportion of emperors and drums, however, increased in demersal zone D on the
recent surveys - although this is probably a result of some single large catches of these
species. Threadfin breams are present in similar proportions in zone A and B with a
possible decrease in Zone C on the Al Mustaqila 1 surveys.

Fish distributions and the OMZ
The oxygen minimum zone (OMZ) is a zone of low oxygen water which extends from just
below the mixed layer to depths of more than 1000 m in some areas. The core of this layer
defined as the region where oxygen is less than 0.1 ml l-1. Small organisms are
physiologically limited by dissolved oxygen levels less than 0.1 ml l-1 . Demersal fish and
crustaceans (motile organisms) are rarely found where oxygen concentration are below 1.5
ml l-1, while small fish are restricted at levels around 0.3 ml l-1 (Ashjian et al. 2002).
The top 22 demersal species were rarely found within OMZ waters. Occasional catches
within the OMZ tended to be in areas where low and high oxygen CTD casts were close
together; catches within the OMZ may actually have been in oxygenated water, but were
plotted as in anoxic water due to the data matching conditions. Most of the key demersal
species were found closer to the coast on OMA0701 (Sept–Oct) and OMA0803 (AugustSept), when the OMZ was widely prevalent. By OMA0801 (Jan–Mar), when most of the
shelf waters were well oxygenated, fish were widely distributed throughout the survey
area.
During the pre-SW monsoon period (Apr–Jun), waters were largely deoxygenated and
most species were again in a narrow band near-to-shore (e.g., Cheimerius nufar, Drepane
longimana. Some species were rarely captured within the survey area by the demersal trawl
(e.g., Arius tenuispinis, Carangoides malabaricus). This may be because fish moved
inshore to waters shallower than those surveyed (< 20 m) or into the pelagic zone. The
twenty-two demersal species were present mainly within Masirah and Sawqirah Bays after
the SW monsoon 2008 (Aug–Sept), which were well oxygenated compared to other zones
within the survey area.

SMALL PELAGIC FISH SURVEY
3.1 OBJECTIVES AND METHODS
We carried out a series of 5 acoustic surveys of small pelagic fish in the continental shelf
area (20-250 m depth) of Oman between Ras-al Hadd and the Oman-Yemen border, with
the following objectives:
-
To estimate the abundance and distribution of small pelagic fish species on the Oman
continental shelf based on a stratified random transect design, with a target
coefficient of variation of the estimate of less than 30%.
-
To provide, as far as possible, a base for comparison with results from surveys
carried out in the area in 1975-76, 1983-84 and 1989-90.
-
To provide a good quality baseline for comparison with future surveys to monitor
these resources.
-
To collect relevant oceanographic and bathymetric information, and biological
information on all species collected during the survey.
Details of all methods used for this survey are provided in Technical Report 3.
Survey design
The survey area was stratified into 4 strata (Fig. 1). Each stratum covered areas from 20 m
depth out to 250 m. Stratum P1 extended from Ra’s-al Hadd to Masirah Island (total area
6,090 km2), stratum P2a from Masirah Island to Ra’s al Madraka (total area 7,666 km2),
stratum P2b from Ra’s al Madraka to Ra’s Hasik (total area 17,433 km2), and stratum P3
from Ra’s Hasik to the Oman/Yemen border (total area 2,011 km2). Previous surveys
indicated that Ra’s al Madraka often had high concentrations of fish around it, hence the
classification for sub strata P2a and P2b. Most survey effort was placed into stratum 2, it
being the expected area with the most fish. Lesser effort was placed into strata 1 and 3.
We carried out the surveys with 8 transects in stratum 1, 30 in stratum 2 (P2a and P2b
combined), and 8 in stratum 3. This equates to slightly more than the transect density used
in the 1983/84 surveys and markedly better than the 1989/90 survey. Transects were run
approximately perpendicular to the general coastline and, as far as possible, were parallel to
each other in each stratum. The position of each transect was allocated randomly, but with
an enforced minimum spacing of 1.5 nm to reduce correlation between adjacent
transects.Biomass estimates for the identified species or group of species were produced
along with coefficients of variation (c.v.). The echo-integrals were partitioned based on the
pelagic species distribution as sampled by trawl and catch decomposition. A frequencydependent difference in backscattering between 38, 120, and 200 kHz was used (when
available) to identify and discriminate marks. Frequency response can be particularly useful
to separate plankton and fish.
All survey activities were performed during the night, when organisms are not as close to
the surface (where they are not available to acoustic sampling) and are more dispersed,
making them suitable for the echo-integration technique. Operation of the echosounders
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary

was mostly automatic and intended to record acoustic data at all times, including during
trawls, steaming between acoustic transects and trawl stations, during CTD casts and on any
other suitable survey activity.
Strata (dark blue) for small pelagic fish survey.
Survey operation
Echograms were scrutinized throughout each survey and the species composition of
acoustic marks was identified by a combination of directed midwater trawling, study of
mark characteristics (location, depth, shape, intensity, differences in echo strength at 38,
120 and 200 kHz), and other data when available (e.g. underwater video camera images).
Acoustic data were recorded on all available frequencies at all times. The CTD was
deployed at least once per transect to measure water properties and to allow estimation of
the sound speed and acoustic absorption in the survey area.
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
37
Acoustic calibrations were performed following recommended procedures (Foote et al.
1987, Simmonds and Maclennan, 2005). Three attempts were made to calibrate the sounder
on each survey. The principle of each calibration was to suspend a standard tungstencarbide sphere (38.1 mm diameter) under the vessel from three different points to position
and move it within the acoustic beam of the transducer. The same procedures were
followed for all three transducers (38 kHz, 120 kHz and 200 kHz).
Survey Equipment
Scientific echosounders. A Simrad 38 kHz split beam transducer was used to collect
acoustic data on all five voyages. In addition, a 120 kHz and 200 kHz transducers were
also used in surveys 3, 4, and 5. All three transducers were hull-mounted towards the front
of the Al Mustaqila l.
Conductivity, temperature and depth measurement. Depth, water temperature, salinity, and
dissolved oxygen content were collected throughout the surveys using an RBR CTD
deployed from the front of the vessel while it was travelling at a speed not greater than 1
metre per second. Details on oceanographic data measurements are reported in Technical
Report 5.
Pelagic trawls. The “small anchovy” midwater trawl was used to sample in shallow water
for the small inshore pelagic species. The mouth area of the trawl was 308 meshes in
circumference and used 800 mm meshes in the fore part of the net. The cod-end was 20
metres long and used a 16 mm liner. The headline height averaged by survey ranged from 9
to 12.7 m. The net was rigged with standard Thyboron Type 7 trawl doors and 150 m
bridles. A larger “P55” midwater trawl was also used on some occasions during the small
pelagic survey.
Underwater camera. An underwater video camera was deployed where possible to identify
pelagic marks along some of the transects. The camera was deployed slowly over the side
of the vessel while drifting. Deployment was paused at intervals for 1 to 5 minutes to
observe passing marks in different layers. The camera was also held just above the seabed
to collect information on seabed habitat, before being retrieved. The camera was equipped
with two light-emitting-diode diving torches secured parallel to the lens and was also fitted
with stereographic lasers to enable the estimation of scale in images.
Target species
Based on the small pelagic species seen during the previous surveys (Johannesson 1995,
Strømme 1986) we expected to observe the following small pelagic species:
Decapterus russelli
Dussumieria acuta
Etrumeus teres
Rastrelliger kanagurta
Sardinella gibbosa
Sardinella longiceps
Selar crumenophthalmus
Stolephorus punctifer
Trachurus indicus
– Indian scad
– Rainbow sardine
– Round herring
– Indian mackerel
– Goldstriped sardinella
– Indian oil sardine
– Bigeye scad
– Arabian scad

Target strength data collection
Target strength data were collected when large aggregations of dispersed targets were
observed. At least three attempts at collecting in situ target strength data were made on
each voyage. When an aggregation was identified, the vessel was set up to drift or travel at
slow speed (2-4 knots) over the fish and the echosounder ping rate was set to maximum.
Data were recorded for 20 to 45 minutes, depending on time available, the extent of the
aggregation, and the quality of the data. The data were analysed by applying single target
detection and tracking algorithms to the regions identified as containing fish echoes.
Target Identification
Pelagic trawl samples were used to identify and discriminate marks where possible. When
an aggregation was identified on the sounder, its position was recorded and the vessel
turned around to deploy the pelagic net, which was towed for 15 to 30 minutes across the
mark at a speed of 2.8 – 4.0 knots. Catches were sorted by species and weighted on motioncompensating scales, and a sample of individuals was measured. The number of species and
individuals used for measurement depended on available resources (staff) and information
from prior tows in the area (both pelagic and demersal). Detailed information on procedures
is reported in Technical Report.2.
Marks were identified based on two criteria: 1) the percentage of species catch weight as a
proportion of the total catch, and 2) the number of individuals caught. The net used to
sample marks was too small to accurately sample large and fast swimming fishes. For those
reasons these species were not used to define aggregation types, but their contribution to
acoustic backscatter was used in catch decomposition. Other data that were used (when
available) in interpreting the types of marks include underwater video camera footage,
target strength experiment and track analyses, and comparison of mean volume backscatter
at different frequencies. Based on these criteria a series of mark types were defined and
described.
Mark identification using underwater camera
The video camera images collected along acoustic transects were used mostly to confirm
the presence of plankton or detritus layers observed on the sounder. These were used
qualitatively (not quantitavily) in combination with other sources of data (backscatter
property, midwater trawl samples).
Small Pelagic Fish Survey Analysis
The acoustic data were analysed using the echo-integration technique (Simmonds &
MacLennan 2005), as implemented in NIWA’s echo-integration software (esp2, McNeill
2001). Biomass estimates were produced with associated coefficient of variations (c.v.).
The c.v.s include allowance for errors in:
- Echosounder calibration
- Acoustic absorption and speed of sound errors
- Acoustic shadow zone
- Uncertainties in target strength
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
39
Acoustic data were corrected for vessel motion (Dunford 2005, Stanton 1982), although in
the relatively shallow depths of the survey area this correction is small. The data were
corrected for changes in sound speed and acoustic absorption based on CTD measurements
(Fisher & Simmonds 1977, Francois & Garrison 1982a, 1982b).
The echo-integrals were partitioned based on the pelagic species distribution as sampled by
trawl and catch decomposition. A frequency-dependent difference in backscattering
between 38, 120, and 200 kHz was used (when available) to identify and discriminate
marks. Frequency response can be particularly useful to separate plankton and fish
(Sætersdal et al 1982).
Assumptions for conversion of acoustic backscatter to fish biomass
The most important aspect of conversion of acoustic backscatter to fish biomass is the
accurate identification of targets. Mark identification is particularly difficult in mixed
aggregations as it greatly depends on the tools used and relies on the acoustic operator’s
experience. This is where most of the uncertainty and variability can occur, especially in a
highly dynamic system with a wide range of species co-occurring. In this study we
primarily used midwater trawling to identify marks. Trawl selectivity is therefore an
important issue, along with species-specific catchability (Casey and Myers 1998,
O’Driscoll 2003). Since only a small proportion of the total area covered by the transect
can be sampled with the net, the rest of the marks within the survey area must be assigned
subjectively, based on their proximity to a previous catch, the appearance and
characteristics of the marks (including frequency-response), and any other data available.
If we assume that all marks have been accurately assigned, the conversion of the
backscatter to biomass then relies on the accurate partitioning of the backscatter within
these mark types, which is also determined from the proportion of catch and subject to
catchability issues. The conversion to biomass also relies on accurate target strength (TS)
estimates for all of the species present. Because of the high in-situ densities observed
within the survey area, most of the time it was impossible to resolve single targets and
collect TS data on local aggregations. For a number of species there are some reference
values in the scientific literature, but certainly not for all the species encountered.
For all these reasons, biomass estimates should be viewed with extreme caution,
understanding the sources of variability that may affect them.

RESULTS
Target strength and mark identification using midwater trawls
Marks were identified based on two criteria: 1) the percentage of species catch weight as a
proportion of the total catch, and 2) the number of individuals caught (where for example
only one large fish comprised for more than 60% of the catch by weight). Large individuals
such as barracudas that often only comprised 1 or a few individuals per catch did not
appropriately represent the targeted aggregations.

There were up to 25 successful mark identification trawls on each of the 16 mark
categories identified. All tows caught a mix of species. To estimate the acoustic density of
the key species in the mark, it is necessary to partition the acoustic backscatter on the basis
of the associated trawl catch. This was done by applying the “standard” method used in
fisheries acoustics (Simmonds & MacLennan 2005), which assumes that all species which
contribute to the backscatter are caught in the trawl, and that all species have equal
catchability. The assumption of equal catchability is almost certainly incorrect (O’Driscoll
2003), but this method allows us to provide a useful “ball-park” estimate of the abundance
of key species.
A total of 201 species were caught in mark identification trawls. To reduce the complexity
of the computations, these 201 species were grouped into 25 groups, based upon their
relative abundance and their taxonomy and morphology. The mean target strengths of each
group were estimated from published target-strength relationships for analogous species
and length and weight data collected during all five surveys.

Similar species that were co-occurring and had overlapping length distribution were

Results of in situ target strength measurements are listed in Tecnnical Report 3-Appendix 7.
In many cases it was impossible to resolve single targets due to high local density of fish or
the presence of smaller particles in the water column. In a number of experiments where
targets were properly isolated, identification was problematic because of the wide range of
species collected in the midwater trawl. Results for experiments on scads, sardines, and
other clupeids were compared to literature values. All values are higher than the published
target strength to length (TS-L) relationships. Scads are the species with the best agreement
and seem to follow the same slope as the TS-L relationship for jack mackerel (Trachurus
symmetricus), except for fish larger than 20 cm. For sardines and clupeids there were only
two experiments with reliable data. Small clupeids yielded values more than 10 dB higher
than predicted from published TS-L relationships on similar species. Data on sardines and
clupeids are however confounded by multiple targets (echoes from more than one fish
interpreted as single fish) due to the schooling nature of these species and the presence of
larger fish (potentially predators) in their vicinity, as observed from the catches. Three more
experiments on different species provided valid data and are presented in figure 13. These
were in fairly good agreement with published TS-L relationships on similar or
morphologically closely related species.
Small pelagics distribution and seasonality
The Arabian and Indian scads were the most widely distributed of the small pelagic
species. The core of the distribution was in stratum P2b between Ra’s al Madraka and Ra’s
Hasik, but they were also found in the other strata. Scads were found in layers extending
over deep water, up to 250 m bottom depth. They were also often seen in layers associated
directly with the bottom, as well as in midwater.
Sardines (Sardinella species) were found in patchy schools in shallow waters, typically less
than 40 m deep. These schools often extended from the bottom to the surface. Most of the
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
42
sardine schools were observed in stratum P2a, between Masirah Island and Ra’s al
Madraka.
Clupeids (slender rainbow sardine and red-eye round herring) were also observed in dense
schools in stratum P2a. Typical aggregations were close to the surface (upper 10-15 m of
the water column) but over deeper waters than sardines. Some extensive aggregations were
observed in stratum P2b in 2008, consisting of a series of small dense surface patches or
clusters. Even in deep water (~100 m) clupeid schools were always close to the surface.
A similar surface distribution was observed with anchovies. Anchovy aggregations were,
however, not seen or identified as often as other schooling fish (sardines and other
clupeids). Like sardines, anchovies also tended to occur more in shallow waters, but not
exclusively. Particularly strong aggregations of anchovies were observed during the pre
SW Monsoon (OMA0802) in the shallow end of stratum P1, between Ra’s al Hadd and
Masirah Island. Very few schools of anchovies were identified in the following survey
(OMA0803), with the exception of a small aggregation in the deeper end of stratum P3
close to Ra’s Hasik.
Layers with myctophids were observed within the survey area in the post SW Monsoon to
NE Monsoon surveys, with some weak layers in strata P3 (OMA0701) and P1
(OMA0702). More significant layers of myctophids were only observed in the spring interMonsoon survey (OMA0801), in strata P1 and P2b. Layers in the southern part of P2b,
between Ra’s Sawqirah and Ra’s Hasik, extended all the way to the shallow end of the
depth range.
Strong layers dominated by the Oman gaper were only observed during the first post SW
Monsoon survey and the NE Monsoon surveys, with layers in strata P1 and throughout
P2b. No layers of Oman gaper were observed in the repeated post SW Monsoon survey
(OMA0803). Layers of ridged swimming crabs extending within our survey depth were
observed during the post SW Monsoon to NE Monsoon surveys in 2007 in strata P1. Crabs
were observed again in the pre SW Monsoon survey (OMA0802) in stratum P2a close to
Ra’s al Madraka and on the last post SW Monsoon survey (OMA0803) further south in
stratum P2b off Ra’s Sawqirah.
Layers of larger targets such as catfish and largehead hairtail were also identified. Layers
of catfish were observed during the post SW Monsoon surveys, with particularly strong
concentration in stratum P2a in voyage OMA0701 and to a less extent in stratum P1 during
voyage OMA0803. Concentrations of largehead hairtail were only observed in the 2008
voyages, with aggregations in stratum P2 (a and b), often around Ra’s al Madraka.
Extremely dense surface schools of small juvenile hairtail were encountered during the last
SW Monsoon survey off the bay of Sawqirah in stratum P2b.
Lanternbellies were identified during the NE Monsoon and spring inter-Monsoon surveys
with aggregations in midwater over the deeper end of our survey range (100-250 m). Other
species aggregations encountered during the surveys, the stripped boga (boops lineatus) and
Randall’s threadfin (Nemipterus Randalii), were found in a few dense aggregations over
shallow water (less than 50 m).

Scads were the most abundant of the small pelagic species, with biomass ranging from just
under 800 000 tonnes to more than 2 million tonnes. Coefficients of variation for scads
were low (below 20% in all voyages) because of their wide distribution within the survey
area. Other small pelagic species were more patchily distributed and have relatively high
coefficients of variation.
Sardines biomass estimates were quite high, reaching almost half a million tonnes during
the post SW Monsoon voyages. Coefficients of variation were lower on these two voyages
as well, suggesting a more uniform distribution.
Other clupeids biomasses were lower with a mean of about 160 000 tonnes across voyages.
Anchovies were the less common of the small pelagics schooling species, with relatively
low biomass estimates (~10 000 - 40 000 tonnes) with the exception of the pre SW
Monsoon survey (OMA0802), where large aggregations were identified in the north
resulting in a biomass estimate of more than 180 000 tonnes.
The combined total biomass estimates (tonnes) of all main “true” small pelagic species,
including the scads, sardines, clupeids, and anchovies was:

The largest biomass was recorded during the pre SW Monsoon survey, with a total of more
than 2.7 million tonnes. The other four surveys were comparable, with biomass ranging
from 1.4 to just above 2 million tonnes. The total biomass of all species estimated during
the survey ranges from 1.9 to 3.1 million tonnes.
Other categories or species estimated during the small pelagic survey have highly variable
biomass estimates and were not encountered or identified in all of the surveys. Myctophids
were found in large quantities within the survey area during the spring inter-Monsoon
survey (OMA0801) with a biomass just under 400 000 tonnes.
Other species that may have distribution outside of the survey area (deeper water) include
lanternbellies and ridged swimming crabs. Large quantities of lanternbellies (> 140 000
tonnes) were recorded during the NE Monsoon survey (OMA0702). Of the larger fish
species, catfish and largehead hairtail categories yielded high biomass estimates in some of
the surveys. In particular, estimates of catfish during the first Post SW Monsoon survey
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
46
(OMA0701) were more than half a million tonnes. Largehead hairtail were identified in the
last two surveys with biomass in excess of 150 000 tonnes. In addition large schools of
juveniles were encountered during the last post SW Monsoon survey that also yielded a
biomass of more than 325 000 tonnes.
General observations
The total backscatter in the survey area was high in all the surveys. A proportion of this
backscatter, particularly in the post SW Monsoon surveys, can be attributed to dense layers
of plankton and detritus, as observed with the underwater camera. The most abundant fish
scatterers were the scads (Arabian and Indian scads combined). Small schooling species
(Sardine, Clupeid, and Anchovy categories) were predominantly found in shallow waters
(less than 50 m depth). The distribution of these small pelagics was very patchy and they
were found mostly in strata P2 (P2a and P2b combined), with some notable exceptions, for
example a particularly strong aggregation of sardine just off Al Masirah in stratum P1
during voyage OMA0701. Scads were also predominant in stratum 2, but were found over
a wider range of depth.
These patterns were also observed during the Rastrelliger surveys. Scads often formed
layers that moved a lot within the water column, suggesting that they were orienting
themselves at the oxygen minimum layer or a thermocline. At other times aggregations of
scads appeared to be strongly associated with the bottom. Small schooling fish such as
sardines and anchovies were found predominantly in the shallow end of our survey range.
This suggests that a significant proportion of these species is located outside the survey
boundaries, in water shallower than 20 m. Furthermore, many schooling species, especially
in the clupeids and anchovies acoustic categories, were found in the upper part of the water
column. This suggests that a large proportion of the biomass was within the acoustic deadzone, the volume of water that cannot be sampled by the hull-mounted echosounders. With
a vessel draft of 5 m, and a transducer near-field resonance of 2 m, this dead-zone will be
at least 7 m, which is significant.
It should also be noted that during the first two voyages (OMA0701 and OMA0702) we
observed large quantities of plankton and detritus with the underwater camera.
Decomposing detritus from phytoplankton may produce gas that would generate high
backscatter. It is almost impossible to decouple this backscatter from the one produced
from fish shoals when they are mixed together. This suggests that the biomass values
presented here may be inflated. However, our highest biomass estimates for small pelagics
was recorded during the pre SW Monsoon survey before significant decomposition occurs,
which suggest that contributions from detritus and decomposing matter may not be as
significant as previously thought.
It is also important to note that the biomass of certain categories could only be estimated
when aggregations were properly identified. This is especially important for highly patchy
species such as anchovies. Furthermore, the fact that many categories (e.g. Boops lineatus,
Randall’s threadfin, catfish) were only seen in dense aggregations in some of the surveys
suggest high dynamics within the system. This confounds our ability to properly estimate
biomasses, especially since we did not cover the inshore areas (less than 20 m depth).
Many species we encountered also have distributions over depth ranges outside our
boundaries (deeper water). This includes myctophids, lanternbellies, and ridged swimming
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
47
crabs. The fact that these species were sometimes found well inside our survey boundaries
suggests a strong coupling with the offshore region extending from the shelf in this area.
This coupling most likely depends on a series of factors difficult to model or predict.
Biomass estimates presented in this report do not include the background acoustic
component (e.g. biomass of scads outside scads aggregations) of each category, so in many
respects these estimates represent minimum values (assuming proper identification and
assignment of marks). Furthermore, a significant proportion of the total backscatter was not
assigned to any species or category because of failure to properly identify or categorize
marks. In some instance this may represent plankton or detritus layers, but in many case this
corresponds to mixed assemblages of fish. The true total biomass of pelagic fish for the
coast of Oman may well be above the estimates presented here.
3.3 COMPARISONS WITH PREVIOUS SURVEYS
Comparisons of biomass estimates to those obtained from previous surveys should be done
with caution. Differences in general approach, methodology, equipment used,
computations, and conversion factors can have significant impacts on the estimates.
The Fridtjof Nansen surveys used target strength to fish length relationships that have
since been improved. Improvement in echosounder technology and calibration are also
important.. For example it was noted that the 1975-76 surveys were most likely affected by
measurement saturation. Different surveys may also covers different depth strata. The
Fridtjof Nansen sampled to depth of 15 m, while the Rastrellinger and this survey did not
cover grounds inside 20 m. Also, there are some differences in gears that would
undoubtedly affect survey results, such as difference in the performance and catchability of
different nets on different vessels, which in turn affect interpretation of acoustic
backscatter.
Our estimates of biomass are much higher than those estimated during the Rastrellinger
survey. They estimated a total maximum standing biomass of 252,000 tonnes, comprised
mostly of Sardinella longiceps, Decapterus russelli, Trachurus indicus, and Selar
crumenophtalmus. Our estimates are more in line with the previous Fridtjof Nansen survey
(1983-84) results with scads as predominant species. Our results suggest higher biomass
than ever recorded in this area.
Biomass estimates of small pelagics from Ra’s al Hadd to Ra’s al Marbat (or to the Yemen
border in 2007-2008) are shown below. Rastrelliger estimates are only from Ra’s al Hadd
to Ra’s al Madrakah; areas further southwest were noted as having ‘unreliable’ conditions
for acoustic measurements. (* denotes estimates are only from Masirah Bay). Values for
the 2007-2008 surveys are given as combined estimates for the main small pelagics
species, including scads, sardines, clupeids, and anchovies categories.

RECOMMENDATIONS FOR FUTURE SURVEYS
There are many factors to consider when planning a survey for small mobile pelagic
species. Choices of methods and approach also often depend on a compromise between
various survey operations and priorities. For this work it was decided to survey during the
night using conventional integration when the fish are more likely to be available to
echosounders and scattered. This presented a problem for species identification because
during this time aggregations are often mixed. It has also been observed that many species
still school or aggregate densely close to the surface, making them unavailable to hullmounted echosounders.
During our surveys we did not have success with sonar, as it proved to interfere with our
other acoustic instruments. Furthermore a dedicated sonar survey of schooling fish during
the day was not possible because of bottom trawl survey operations. It is also more difficult
to obtain accurate biomass estimates of fish based on school numbers and sizes.
Nevertheless such a survey could be helpful, as many of the species of interest (such as
sardines and anchovies) form dense mono-specific schools close to the surface during
daytime. Such schools were visually observed on many occasions from the Al Mustaqila 1.
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary

The use of sonar survey would need to be combined with proper sampling tools such as
purse seines to properly identify marks. This may require more than one vessel.
Of particular concern is the proportion of pelagic species likely to be found in shallow
waters outside the survey boundaries. Surveying with smaller vessels would enable survey
of shallower grounds, but the presence of fishing nets would present hazards and limit
survey operations. A possible alternative would be to combine such a survey with aerial
visual surveys from spotter aircraft flying at low altitudes. One advantage of this approach
is that aircraft can cover a lot of ground in little time. Recent advances in technology also
offer promising venues. For example the use of airborne LIDAR (LIght Detection And
Ranging) has been demonstrated as a potential for abundance assessment of similar species
(Carrera et al. 2006).

4 MESOPELAGIC FISH SURVEY
4.1 OBJECTIVES AND METHODS
We investigated mesopelagic fish resources off the Arabian Sea coast of Oman up to 65
nautical miles from the coast on Surveys 3, 4 and 5, with the following objectives:
-
To estimate the abundance and distribution of mesopelagic resources within the
survey area.
To provide a basis for comparison with results from earlier surveys carried out in the
area.
To collect relevant oceanographic and biological information on all species collected
during the survey.
Survey design
Previous surveys indicated a significant increase in mesopelagic density with distance
offshore in some areas (notably off Ra’s al Hadd and the Ra’s Hasik to Mirbaī area) in
spring, summer and autumn. In addition, dense layers were often found from the 200m
contour to approximately 1–2 n. mi. offshore and further offshore, near the banks close to
Oman’s 200-mile EEZ limit. Rastrelliger mesopelagic surveys covered up to 60 n. mi.
offshore, and some surveys by the Fridtjof Nansen extended offshore nearly 150 nautical
miles.
We therefore designed 3 mesopelagic fish acoustic surveys:
-
2 surveys for “offshore” resources, during the late SW monsoon period (August–
September) and during the late NE monsoon period (January–March)
-
1 “nearshore” survey along the continental shelf during the spring intermonsoon
period
“Offshore” survey transects began at the continental shelf edge (at about 200 m depth)
approximately 30 minutes after sunrise or after the completion of the dawn descent. Six
transects were completed per survey. Transects extended for the distance the vessel was
able to steam during daylight hours, including time for target identification tows. Transects
ended when the mesopelagics begin their dusk ascent. Return (shorewards) transects began
after the dawn descent. At night the vessel travelled parallel to shore, collected target
strength data, and completed exploratory fishing where appropriate. The 3 areas that were
surveyed on each offshore mesopelagic survey are shown in Figure 4. Two transect
locations from each area were randomly selected. Spacing between transects was at least
1.5 nautical miles.
“Nearshore” survey transects began at the 200 m contour and extended up to 5 nautical.
miles offshore. They ran approximately perpendicular to the coastline. The 4 areas surveyed
are shown in Figure 4. Transects from each area were randomly selected with spacing
between transects of at least 1.5 nautical miles. 6 transects were completed in Area 1, 4 in
Area 2, 2 in Area 3 and 6 in Area 4.

four “nearshore” (black) strata.
Survey equipment
Acoustic equipment included 120 kHz and 38 kHz transducers, allowing for data
comparison with earlier surveys in the region. Data logging was as specified for the pelagic
and demersal acoustic surveys. Data was also collected using a 200 kHz transducer.
Echograms were scrutinized throughout each survey and acoustic marks were identified
where possible by directed trawling. The CTD/DO probe was deployed at the beginning
and end of each transect during the surveys, and after every target identification tow during
the offshore surveys.
Target identification
Where possible a directed midwater trawl tow was executed to obtain species for
identification and length data. Tows were carried out in locations and depths where marks
were observed and also on areas of low backscatter; this was done to ensure fish with low
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
52
target strength signal were not omitted from the analyses. At least two trawls were
conducted each day that mesopelagic acoustic transects were carried out. Species diversity
increased east to west in the Arabian Sea, therefore target tows increased in frequency east
to west. The catch was sampled as for the demersal trawl survey. Tow duration was usually
approximately 30 minutes at a towing speed of 2–3 knots.
Myctophids were noted escaping through the trawl mesh on previous surveys and mesh
bags were fastened to the sides of the trawl net to determine escapement
Target strength
Target strength was determined for the main species in the scattering layer using the
methods described for small pelagic species.
Details of all methods used for this survey are provided in Technical Report 4.
The area surveyed for mesopelagic resources (Figure 4) encompassed areas of known high
densities of myctophids. This was a compromise between being able to survey
mesopelagics well (and therefore estimate biomass with a reasonable level of confidence)
and the amount of time available to complete the survey. Biomass estimates, therefore,
encompassed only a portion of Oman waters of the Arabian Sea and should not be
extrapolated over the entire area. All estimates are relative biomass estimates, not absolute
biomass. Sources of acoustic error have not been quantified for the purpose of this report.
4.2 MESOPELAGIC SURVEY RESULTS
Mesopelagic catch
Twenty-three midwater mesopelagic target identification tows were completed on
OMA0801, 18 on OMA0802 and 17 on OMA0803. The three surveys captured a total of
88 different species/species groups. In total (all trips), nearly 6 t. of myctophids and 1.5 t.
of ‘other’ species were caught.
Stratum 1 (Ra’s al Hadd area), regardless of time of year, had the highest catches (by
weight). In general, species diversity increased from Ra’s al Hadd to the Oman-Yemen
border. After the NE monsoon diversity increased with distance offshore for most areas.
After the SW monsoon period, diversity increased with distance offshore only off Ra’s al
Hadd and near the Oman-Yemen border.
Myctophid identification was not to species level, but to a myctophid “group” based on key
characteristics. Myctophids were separated into 3 Benthosema species (B. pterotum (BEP),
B. suborbital (BES), and B. fibulatum (BEF)), and 5 Z-code species. Myctophids
dominated the catch on all surveys. Benthosoma pterotum was captured throughout the
survey area, offshore and nearshore. Eleven myctophid groups were caught during
OMA0801, 6 on OMA0802, and 7 on OMA0803. Groups BES and ZAG were only
captured offshore. Group BEF was not found in the northern survey area (stratum 1, all
surveys).
The main components of non-myctophid catches were chondrichthians (e.g., sharks and
rays), swimbladdered fish (e.g., mackerel, scads, sardines, and smelt), deep-sea eels and
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
53
conger eels, jellyfish/salps, larva fish and eels, swimming crabs (Charybdis spp.), shrimps
and squids.
There was little variation in the total number of non-myctophid species caught in
mesopelagic tows by survey. However, by weight, the greatest catches were taken during
the nearshore survey in the inter-monsoonal period. After the NE and SW monsoon
periods, fewer non-myctophid species were caught near Ra’s al Hadd. During the intermonsoonal period, the lowest diversity was found outside Sawqirah Bay. However, this
may be because the transects here covered more of the shelf than the shelf edge. The
highest number of non-myctophid species was observed in the stratum near the OmanYemen border.
Acoustic mesopelagic mark types
Nine mark types were defined (see Technical Report 4); two of the nine types were seen
only on OMA0802 and OMA0803, one type was only seen on OMA0802, and one was
seen only on OMA0803.
Species within each mark type were categorized based on the expected amount of acoustic
backscatter they would reflect. Because most layer types were a mixture of species,
backscatter was partitioned by acoustic group before estimating biomass.

Myctophid densities and biomass
After the NE Monsoon (Feb-Mar) average densities were moderately consistent across
each of the offshore areas surveyed, averaging around 19 t km–2. During the pre SW
monsoon period (Apr-Jun) densities in the nearshore areas off Ra’s al Hadd (Stratum 1)
had increased dramatically (to 155 t km–2). Densities in the other nearshore areas surveyed
remained low (< 4 t km–2). After the SW monsoon (Aug–Sept) densities were still very
high in Stratum 1 (at 72 t km–2) but had droppd to low levels in the other offshore strata (<
2 t km–2 ) (Tables 13 and 14).

Total myctophid biomass was highest immediately after the SW monsoon period off Ra’s
al Hadd. Biomass estimates were approximately 1.2  106 t, however, confidence intervals
were extremely high (+/- 1.1  106 t) due to high sampling variance.
Myctophid biomass was generally highest in the area off Ra’s al Hadd during all periods
surveyed. This is not surprising as this is an area of high productivity throughout much of
the year. In this area biomass was highest during the spring intermonsoon period. This is
most likely a lagged effect of the extremely high productivity caused by upwelling during
the NE monsoon in the Gulf of Oman and north of Massirah Island.
Mesopelagic densities and biomass
Average estimated densities and biomass for most mesopelagic species was highest off
Ra’s al Hadd following the SW monsoon period, except jellyfish and salps, which was
higher in the two southern strata. For all other survey periods, biomass was relatively low
for other mesopelagic species, except for squids. Squid biomass was relatively high off
Ra’s al Hadd during the intermonsoon period (April-June).
After the SW monsoon, total mesopelagic biomass off Ra’s al Hadd was three times greater
than the estimated biomass from other areas. After the NE monsoon period, mesopelagic
biomass was highest south of Massirah Island. During the intermonsoon period (AprilJune), total biomass was highest near the Oman-Yemen border.

Areal trends
Myctophid densities were highest near the shelf edge on all surveys. For the offshore
surveys, myctophid density, once past the shelf edge, was fairly consistent and relatively
high with distance from shore in the Ra’s al Hadd area. This trend was found in all areas
surveyed immediately after the NE monsoon period. After the SW monsoon, myctophid
density was high in the southern two strata only at the shelf edge.
Other mesopelagic species groups had high densities in the area off Ra’s al Hadd for most
seasons surveyed. Squids, swimming crabs and jellyfish tended to be most dense
throughout the survey area immediately following the SW monsoon period. Highest
densities of swimbladdered, deep-sea fish and shrimps were measured after the NE
monsoon .
4.3
COMPARISONS WITH PREVIOUS SURVEYS
As noted by Gjøsæter (1981), several factors contribute to good acoustic estimates of
myctophids in the Arabian Sea: scattering layers are nearer to the surface than in many
other regions, the main myctophid species possess an air-filled swimbladder, and
myctophids form dense layers that include few other organisms.
In this project we found extremely dense layers of myctophids at depths of 100–250 m
(sometimes shallower), extending from the shelf edge up to 60 n.mi. offshore, The
myctophid layers were typically 10–50 m thick and included dense schools. These layers
were well separated from the deep scattering layer, a diffuse layer containing a mixture of
deep-sea species, including myctophids. Dense myctophid-only layers were seen in earlier
surveys in the area and were noted as consisting of small schools, typically 20–40 m thick
(Venema 1975, Gjøsæter 1977, 1981, 1984).
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
59
Gjøsæter (1984) noted that these distinct myctophid layers were found only where
Benthosema pterotum was the dominant species; however, the results of the 2007–08
surveys do not support this statement. These layers were found throughout the surveyed
areas, including in areas where Z-code myctophid species dominated the catch. FAO
(1995) concluded that layers of myctophids dense enough to allow targeted trawling only
occurred at depths of 130–250 m; deeper layers were too mixed to support a viable fishery.
Estimates of myctophid biomass were compared to earlier surveys in the Arabian Sea (see
below).

Estimates from 2007–08 are of a similar order to estimates by the Rastrelliger (1989–90),
but much lower than estimates by the Fridtjof Nansen (1975–76).

Al Mustaqila I biomass estimates are from an area intermediate in size between the Fridtjof
Nansen (which covered the entire Arabian Sea coast of Oman) and Rastrelliger surveys.
Sætersdal et al. (1999) stated some biases were apparent in the early Fridtjof Nansen
surveys and were most likely due to inadequate acoustic identification and sampling; the
high biomass estimates were questioned and concluded to be dubious.
Estimates from the Rastrelliger survey were only from the area off Ra’s al Hadd. The
reported estimate was averaged from two time periods, immediately after the SW monsoon
(August) and the autumn intermonsoon period (November), making comparisons difficult.
Biomass estimates from 2007–08 from the Ra’s al Hadd area immediately after the SW
monsoon period were approximately 2.5 times higher. However, after averaging all periods
in a manner similar to the Rastrelliger report, biomass estimates in the Ra’s al Hadd area in
2007–08 were within the confidence interval of the Rastrelliger 1990 estimate.
Species diversity typically increased towards the Yemen border and with distance offshore
as reported from earlier surveys (Venema 1975, Gjøsæter 1977, 1981, Aglen et al. 1982).
Benthosema pterotum was the dominant species found through the survey areas. Shallow
scattering layers consisted mainly of myctophids, but deep scattering layers contained a
wide mixture of species; this is similar to the findings of Gjøsæter (1981) and Venema
(1975).
The 2008 survey areas were areas of expected high biomass. Estimates of density show that
these areas did indeed have exceedingly high biomass of myctophids, which ranged from
less than 1 t km-2 to more than 200 t km-2. This is similar to previous density estimates from
this region. Gjøsæter and Kawaguchi (1980) show estimates of myctophids in the Arabian
Sea ranging from 15–257 t km-2.
Myctophids were distributed patchily both spatially and temporally, as found in previous
surveys (Venema 1975, Gjøsæter 1977, 1981, 1984). Myctophid biomass was high off Ra’s
al Hadd in all surveys, high south of Massirah Island only after the NE monsoon period,
and high near the Oman-Yemen border in the spring intermonsoon period (April–June).
Average estimated myctophid biomass was typically high along the shelf edge. This is
consistent with results from earlier surveys, which found dense layers extended from the
shelf break up to 4 km offshore (Aglen et al. 1982, Gjøsæter and Tilseth 1983).
Myctophid density did not decrease with distance offshore in the Ra’s al Hadd area. This
may be because myctophids are taking advantage of increased productivity and
zooplankton biomass resulting from the SW monsoon and again after the NE monsoon.
The Findlater jet, an offshore current that develops during the SW monsoon, drives open
ocean upwelling during the SW monsoon and autumn intermonsoon periods (Smith and
Bottero 1977). Previous surveys in the area found high mesopelagic biomass inshore of the
Findlater jet (Venema 1975, Anonymous 1976a, Koppelmann and Weikert 1997, Wishner
et al. 1998, Luo et al. 2000, Ashjian et al. 2002).
Earlier studies found mesopelagic biomass decreased in the Ra’s al Hadd area after the SW
monsoon period by as much as 50% (Anonymous 1976b, Strømme and Tilseth 1984,
Ashjian et al. 2002). Consistent with that observation estimated average biomass (t km-2) of
myctophids after the SW monsoon period in this study was half that estimated in the spring
intermonsoon period (April-June). Increased mesopelagic biomass in April–June is most
likely a lagged effect of the high production in the preceding months.Winds from the NE
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary

monsoon fuel increased primary production in the Gulf of Oman and Ra’s al Hadd region
(see SEAWiFS figures, Technical Report 5). However, a very different picture was
apparent once biomass was estimated for the entire strata off Ra’s al Hadd. Myctophid
biomass (in the entire strata) was highest off Ra’s al Hadd during the spring after the
interSW monsoon period. (April–June) Confidence intervals of this estimate were
extremely wide due to high variability of mesopelagic biomass (t km-2) along the transects.
Myctophids were regularly found in the oxygen minimum zone, particularly when in the
mixed deep scattering layer (typically found at depths > 300 m). Wishner et al. (1998)
found mesopelagic organisms migrated deep into the OMZ, even when this zone was at
depths greater than normal. Previous studies also found myctophids appeared to take refuge
in the deoxygenated layers (Gjøsæter 1977, 1981, Kinzer et al. 1993). The dense
myctophid-only layers were typically found in at the border between oxygenated and
deoxygenated water, which may explain why these dense layers form.

EXPLORATORY SURVEY ON UPPER
CONTINENTAL SLOPE
5.1
OBJECTIVES AND METHODS
The Arabian Sea coast of Oman has a realively high primary productivity and it has been
suggested that significant fishery resources may be available in waters deeper than 250
metres, on the upper part of the continental slope. No information exists on such resources
on which to base the design of a survey of a standard similar to the demersal fish trawl
survey for the region less than 250m deep. Therefore, in conjunction with the trawl survey,
we conducted a series of exploratory tows in depths between 250 m and 1000 m to
investigate the nature and abundance of potential deepwater demersal fisheries resources.
The objectives were:
-
To evaluate the species present, their abundance, distribution, and seasonal variation
-
To investigate relationships with habitat and oceanographic conditions, particularly the
oxygen minimum zone.
We defined 3 strata (see below) in depths between 250 m and 1000m; a northern stratum
between Ra’s al Hadd and Ra’s Hasik; a southern stratum from Ra’s Hasik to the Yemen
border; and the Murray Ridge (a prominent feature which runs in a northeasterly direction
about 150nm off the Arabian Sea coast of Oman).
Opportunities for exploratory trawls were sought, when the vessel was carrying out other
survey activities, by monitoring of acoustic data collected while the ship was underway.
Information was also made available from recent commercial fishing trawls conducted in
the 250-1000m depth range from the survey vessel (Al Mustaqila 1).
At each potential site the ship first surveyed the tow with echosounder equipment to
determine whether the bottom was suitable for trawling and if there were any acoustic
marks indicating the presence of fishable resources. Tows were carried out using the
standard survey trawl (or midwater trawl as appropriate) with the trawl on the bottom for
1.5 to 2.0 nautical miles at a speed of approximately 3 knots.
Biological, acoustic and oceanographic data collection were as for the standard demersal
trawl survey tows. All bathymetric and bottom type data were retained and deposited in the
appropriate databases.
Details of all methods used for this survey are provided in Technical Report 2.

EXPLORATORY SURVEY RESULTS
Attempts to find trawlable ground on the continental slope off survey Zone A were limited
to one small area. The rest of the zone was too rough or steep to successfully deploy the
trawl. The slope in Zones B and C had good areas of trawlable ground although the
northern part of Zone B and the southern sector of Zone C were too steep and rough to
trawl on. Demersal zone D in depths greater than 250 m had very steep and untrawlable
ground to the north and south of the area, with a section in the middle, off Salalah, having
good trawlable ground. The maximum depth fished was 843 metres. The number of valid
exploratory trawls in each stratum of each survey was:

The southern stratum appeared much more promising with good catches, although mainly
of species attaining a small size. The largest single catch from all trawl stations was 15,197
kg taken on OMA0802 station 501 during an exploratory trawl in the southern stratum.
Catches of Arabian whip lobsters (Puerulus sewelli) in this area showed promising signs
of a potential commercial fishery. The trawl gear used is not particularly effective at
catching this species as the groundrope is too high to effectively sample them, so dentieies
estimated here are like;y to be conservative.
Small specimens of alfonsino (Beryx splendens), a commercially important species, were
also taken.
Six trawls were completed on the northern part of the Murray Ridge. Catches were very
small. One feature on the Murray Ridge was the quantity and variety of rubbish caught. A
second ridge to the south was surveyed but due to the rough nature of the seafloor no trawls
were attempted.

6 HABITAT, BIODIVERSITY AND OCEANOGRAPHY
6.1 OBJECTIVES AND DATA COLLECTION
Physical oceanographic and bathymetric data collection
The vessel was fitted with a data acquisition system for the collection and storage of lowvolume data while underway. A data logging computer collected and stored:
-
Vessel position, speed, and course from a non-differential GPS receiver (position
accurate to ±10 m, speed to 0.5 knots, course to ±2º).
Vessel heading (±1º).
True wind speed and direction (speed to ±1 knot, direction to ±1 º).
Air temperature (±1.5ºC).
Surface seawater temperature (±0.1ºC).
Water depth (±5 m, uncorrected for vessel heave and tide).
Barometric pressure (±20 mBar).
Relative humidity (±5 % RH).
For physical oceanographic data collection we used RBR XR-620 and XR-420 CTDs to
collect temperature, salinity, depth and dissolved oxygen on every trawl shot and on
acoustic transects. Bathymetric data were logged routinely as part of the underway data
collection process. Further bathymetric data were available through the acoustic survey data
collection undertaken throughput a large part of the survey period. Data were also available
in transit between stations and during examination of areas of untrawlable bottom.
Remote sensing data on chlorophyll A was sourced where it was available for the survey
area during the period of the surveys as an aid to interpretation of fish abundance,
distributions and oceanographic data. Surface chlorophyll concentrations from the NASA
SeaWiFS and MODIS-Aqua sensors were supplied by NASA. Chlorophyll was derived
using the OC4v4 algorithm for SeaWiFS data (O’Reilly et al. 1998), and the OC-3
algorithm for MODIS (O’Reilly et al. 2000). Daily overpasses were composited onto a
standard grid at 9 x 9 km spatial resolution for each month. Chlorophyll values were
rescaled to a range of 0.05 to 8.00 mg m-3 and coastlines added using NASA freeware
Seadas v5.3. Note that the global chlorophyll algorithms have been found to overestimate
chlorophyll in phytoplankton blooms in the Arabian Sea (Nagamani et al. 2006).
Details of all methods used for collecting oceanographic data are provided in Technical
Report 5.
Plankton sampling
The Survey tender documents requested plankton sampling on the survey “to investigate the
relation between plankton and fish abundance and distribution”. In addition, requests were
received from SQU staff for phytoplankton water sampling with particular attention to the
NE and SW monsoon periods, in the inshore areas of the upwelling active regions (Zones A
and B in the survey design), and near the oxygen minimum zone.
Plankton samples were collected, as a minimum, at the beginning or end of each trawl
station in the trawl survey component of the project from surveys OMA0801, OMA0802
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
69
and OMA0803. In addition samples were collected when CTD casts were carried out in
association with other parts of the survey when opportunities arose, such as during the
acoustic transects.
2 x 500 micron mesh zooplankton nets with suitable cod-ends and an opening of 600mm
were available. These were operated as vertical drop nets, sampling as they fell to the
required depth. The nets also fished on the retrieve and effectively filtered 11.3 cubic
metres of water. A 500 ml sample was retained. Water samples for phytoplankton were
collected using Niskin bottles at 1 m and 20m, deployed on hydrographic wire and triggered
using messengers. Samples were delivered to the Ministry of Fish Wealth for analysis at the
end of each voyage. Detailed procedure used for this sampling are described in Technical
Report 5.
Other scientific sampling
Other material such as additional otoliths, reproductive material, stomachs, genetic samples
or parasites was collected as time permitted and according to sampling protocols
determined by the researchers requesting such material. Marine mammal sightings forms
were completed during all surveys.
Spatial habitat and biodiversity information
Data to assist with describing habitats and biodiversity in the survey area arose from:




The catch from all survey sampling
Acoustic backscatter interpretation: at all stages and areas where acoustic
backscatter from the seabed were available.
Video camera sampling
Earlier trawl survey reports.
We attempted to identify all fish and invertebrates collected to species level. Fish
identification guides used included Al-Abdessalaam (1995), Carpenter et al (1997), Fischer
and Bianchi (1984), Froese and Pauly (2008) (FishBase), Randall (1995), Smith &
Heemstra (2003) and Sommer et al (1996). We also reviewed our species identifications
against Fouda et al (1998).
Methods and analytical detail are provided in Technical Report 5.

SPATIAL HABITAT INFORMATION
Categorisation of seafloor types
After the surveys were complete, the camera footage from each deployment was viewed to
ascertain the usefulness in defining the type of seafloor cover in the areas covered by each
camera transect. This assessment resulted in the definition of five broad categories of
seafloor. These are briefly described below.
1.
Thick soft sediment. This category included seafloor areas where there was a thick
layer of sand or sand/mud that was relatively flat, characterised by many pocks and
burrows, or was rippled with sharply defined ridges close together or had broader,
smoother rippling.
2.
Thick sand with rock outcrops or boulders. This category was distinguished from the
one above by the presence of boulders or rock outcrops.
3.
Rock platforms with sand on top. Thin sand cover over expanses of flat low rock
platforms that were generally stepped and contained areas of thicker sand cover in
the shallow wide basins between each rock ledge.
4.
Rock reef fringe with boulders and cobbles. This category described the areas with
the edges of low reef rock characterised by the presence of boulders and cobbles on
sand or rock in the shallow channels between the reef edges.
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
71
5.
Rock reef. Thin sand may fill the crevices and depressions in the hard rock in this
category. The rock cover is rough and uneven and may include piles of large
boulders.
Each camera DVD was viewed and a description of the main bottom type and the visibility
was recorded. These records were then reviewed and each camera station was assigned a
code based on one of the five categories listed above.
Mapping of seafloor types
The station data for each of the camera drops were extracted, combined with the bottom
type category records so that each camera drop station record was assigned a seafloor type
category. These data were loaded into ArcGIS 9.3 (using WGS84 projection datum) with a
base image (produced by NASA’s Earth observatory) that uses a geographic (Plate Carrée)
projection
based
on
an
equal
latitude-longitude
grid
spacing
(see
http://earthobservatory.nasa.gov/Features/BlueMarble/bmng.pdf). Additional map layers
included shapefiles of the survey strata (by demersal zones A–D for depth contours at 20
m, 50 m, 100 m, 150 m, and 250 m) and of the seafloor areas deemed to be untrawlable.
The extracted camera drop station data were joined to the seafloor type data so that each
station record was assigned a code for bottom type. Separate GIS layers were generated,
one for each demersal zone, to map the distribution of the seafloor types.
From a total of 146 camera drops, 111 were able to be categorised by seafloor bottom type
Most data are from the voyages undertaken between November and June, and the footage
clarity was best from camera drops on OMA0801 and OMA0802.
Distribution of seafloor types
The distribution of the camera drops was patchy, with most made in 20–50 m,
especially in Zone B. Drops were made in depths of 19–85 m in Zone A, 18–154 m
in Zone B, 20–73 m in Zone C, and 22–125 m in Zone D. An example of the
distributions of the main seafloor types, based on the start position of each camera
drop, is shown below, with some representative images from the video footage.

OCEANOGRAPHY
Temperature
Sea surface temperature was highest in the autumn intermonsoon period (Sept–Dec),
cooled after the NE monsoon period (Feb), warmed again during the spring intermonsoon
period (Apr–Jun), and was generally very cool immediately after the SW monsoon . Sea
surface temperatures in the Gulf of Masirah tended to be several degrees cooler (up to 5˚
C) than waters to the southwest after the SW monsoon period (Sept) in 2007 and again
during the pre-SW monsoon period. During the autumn intermonsoon period (Nov–Dec),
see surface temperature varied little over the entire survey area.
Sea surface Temperature (˚ C ) March 2008
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
74
Bottom temperatures nearshore ( in the 20–50 m strata) were highest during the autumn
intermonsoon period (Sept-Oct) in 2007 and slowly cooled as the surveys progressed;
bottom temperatures nearshore were coolest immediately after the SW monsoon in 2008
(Figure 20). Bottom temperatures over the entire survey area were at their coolest
immediately after the SW monsoon (Aug-Sept), although a few pockets of warm water
existed (Figure 20). Waters may be cooler immediately after the SW monsoon period due
to wind-induced upwelling and mixing (Figure 20). Bottom temperatures were consistently
cool along the shelf edge throughout the survey area.
Bottom Temperature (˚ C ) August 2008
Salinity
Sea surface salinity varied little throughout the surveys except for immediately after the
SW monsoon period in 2008 when waters south of Masirah Island were less saline. This is
most likely the effect of upwelling, where colder, less saline waters are brought up onto the
shelf. The effect of the SW monsoon appears to be limited, if 2007 was a representative
year. By October (2007), sea surface salinity in the area south of Masirah Bay had reverted
back to the average salinity.
Bottom salinity showed a pattern similar to surface salinity. Less saline water was clearly
visible immediately after the SW monsoon period (Sept) throughout the shelf south of
Masirah Island. Bottom water in the southern strata (zones C and D) became more saline
by October. Bottom salinity was much more uniform throughout the survey area by
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
75
November–December although low salinity intrusions were visibile at mid-depths during
this period.
Dissolved oxygen
Not surprisingly, sea surface oxygen was high (4–6 ml l-1) in all areas on all trips. A
supersaturated dissolved oxygen layer was occasionally present just below the surface (at
10–20 m.
The oxygen minimum zone (OMZ) is a midwater zone of low oxygen which extends from
just below the mixed layer to more than 1000 m in some areas. The OMZ was present
nearshore throughout much of the survey area during the autumn monsoon period (Sept–
Oct) except for pockets of well-oxygenated bottom waters located in Sawqirah Bay in 20–
100 m.
Dissolved oxygen (ml l
-1
) at the bottom September 2007
The extent of the OMZ changed after the NE monsoon period (Jan–Mar). The layer was
not present in shallower waters, but was typically located near the shelf edge. Off Ra’s al
Hadd, the OMZ was located at depths around 150–200 m, while south of Masirah Bay, the
oxygen minimum zone was deeper (around 280 m). Near the Oman–Yemen border, the
oxygen minimum zone was much deeper, at depths greater than 400 m.
Fish Resources Survey of the Arabian Sea Coast of Oman Technical Report 1 – Project Summary
76
Bottom oxygen was low throughout most of the survey area during the spring
intermonsoon period (April–June). Small pockets of high oxygen bottom waters existed in
Masirah Bay and close to shore in survey zones A and D. CTD data collected from the
nearshore mesopelagic survey show the OMZ was located at depths around 50–100 m in
demersal zones C and D.
Although bottom waters nearshore south of Masirah Island appeared to be well oxygenated
following the SW monsoon period, pockets of deoxygenated water were present on the
shelf in areas as shallow as 40–50 m. Bottom waters at depths shallower than 50 m in the
Ra’s al Hadd area were within the OMZ and small pockets of de-oxygenated water existed
in demersal Zone B.

Primary productivity
SW monsoon upwelling-induced high primary production was clearly visible along most of
the shelf edge, including large jets off Ra’s al Hadd, at the Oman-Yemen border, and in the
Sawqirah Bay area.
During the autumn intermonsoon period, the jets disappeared and only Massirah Bay
appeared to remain highly productive. During the NE monsoon, productivity in the Arabian
Sea appeared relatively low. After the NE monsoon, productivity peaked in the Gulf of
Oman and small jets were visible near Ra’s al Hadd. Primary productivity was high in
coastal waters and embayments during the spring inter-monsoon period.
Seasonal patterns relative to the monsoon periods were broadly similar in 2006–2008.
Productivity in 2007 was generally lower than in 2006 (all monsoon periods); primary
productivity was extremely high in 2008, especially after the NE monsoon period
(January–March), extending far offshore and to the coast of Iran. Cloud and dust cover
during the SW monsoon made it difficult to compare years. However, broad patterns (such
as jets off South Oman) were similar in all years.
