1. ABSTRACT
In 1992 an acoustic survey in fjords and shelfareas offFinnmark and Troms, two eounties in
northern Norway, was made to estimate the total biomass of eod, haddoek, saithe, redfish
species and herring to be 876.000 tannes. The total biomass of eod was ealeulated to 112.000
tannes. Based on otolith struetures abOlit 1/3 ofthe eod (34.000 tonnes) was identified as
North East Aretic eod. The remaining, dominant fraction of78.000 tonnes was coastal eod
which form loeal stocks, aeeording to taggirig experiments performed in 1986 - 92.
The biomass of other fish species were; haddoek: 78.000 tannes; herring: 470.000 tomies;
eapelin: 10.000 tannes; saithe: 181.000 tannes and redfish: 25.000 tannes.

2. INTRODUCTlON
2.1 Background
From 1973 40.000 tannes of eoastal eod has been added to the Norwegian quota ofNorthEastem Artic eod. This quota, whieh is still an agreement and used by The International
Couneil for the Exploration ofthe Sea (ICES), is set on the basis ofthe arinual Norwegian
landings of cod in the ICES stiüistieal areas 06 and 07 (Nordland, Tnmdelag, Mere and
Romsdal eounties) during the whole year, pluss the landings in area 00 (Lofoten) in the fourth
and fifth quarters (Figure 1). Based upon these area settings, there are no eoastal eod landings
North ofLofoten. However, the eoastal areas in Finnmark, the northemmost county in
Norway, seem to contain loeal populations of eod, aeeording to JAKOBSEN (1987) who
tagged about 10.000 cod eaught on Ioeal spawning grounds in the fjords.
To evaluate the abundanee ofthe fish resOlirees in north Norwegian fjords and shelfareas, in
1991 Fiskeriforskning initiated a program on the eoastal resources ofnorth Norway, with
funding from The Royal Norwegian Ministry ofFisheries. The planning was based on
investigations made sinee 1985 by the Norwegian College for Fisheries Scienee at the
University ofTromso. The college has used the RN "Johan Ruud" (33 m) to investigate the
distribution and sizes ofwild fish populations in some fjords in the county ofTroms. The
investigations were made before and during the release oftagged eodlings reared from sexual
produets stripped from parent eod from the same fjords, to study enhaneement effeets on loeal
eod stocks. The methods included genetieal separation of sub-populations of eod, haddoek,
: whiting and blue whiting.
In 1992 Fiskeriforskning started the work at sea in the eoastal areas of Finnmark and Trams.
The main objeetive was to evaluate the distribution and stock biomass ofthe most common
eommercial fish species and deep sea prawn. Most ofthe effort was alloeated to eod and
haddoek, but saithe, redfish, herring and capelin were also of important targets.

2.2 Terms of reference
The following tenns ofreference were given to the participants:
1) Assess the abundance arid stock" composition of cod, haddock, saithe, redfish, herring and
.
capelin in coastal areas of Troms and Finnmark in 1992.
2) Give priority to an assessment of cod, with an emphasis on coastal cod. Separation of
parameters versus age is essential.
3) Estimate the stock biomass for the five other species listed above.
4) Estimate maturity ogive, length and weight by age, and spawning stock biomasses of cod.
5) Establish isopleth diagrams for temperature for some main trancects.
3. MATERIALS AND METHODS
All material given in this report was sampled during a cruise using the RIV "Johan Ruud", a 33
m stern trawl-rigged research vessel. All fjords and proximal shelfareas within the 12 n. mile
fishing border from the Russian border, Finnmark County, to Senja, Troms County were
investigated during the period from 24 August to 3 October 1992 (Figure 2 and 3). The
authors were gathered in two periods, in Hammerfest 24 - 31 January and in Bodo 24 -29
May 1993.
3.1 Survey areas and routes
.
.
The investigation occurred in the ICES statistical areas 03,04 and the northemmost part if05
(Figure 1). These areas have been subdivided by the the Norwegian Directorate ofFisheries
(NDF). It was attempted to visit all sub-areas comprising fjords and shelfareas inside the 12 n.
roile border. About 5200 nautical mHes were sailed and the coverage is presented in Figure 2
and 3.
In order to focus on differences between fjords and shelf areas, and study possible gradients
from west to east along the coast, we have grouped some ofthe ICESINDF sub-areas into
larger units. These units will be referred to by names given in Figure 6.
The 1992 survey had a maximum limit of 40 days with the RIV "Johan Ruud". During the
cruise we tried to survey all the major fjords, fjord branches and sounds using overlapping
triangular transects when going in and out ofthe fjord, to get the best possible coverage ofthe
areas (MACLENNAN & SIMMONDS 1992). Parts ofthe major areas to be visited were
planned before the cruise, while some ofthe cruise tracks were planned iri detail during the
actual cruise to get the best possible coverage.

3.2 Acoustic methods
The acoustie integration method onboard RJV "lohan Ruud" was based upon the Bergen Echo
Integration (BEI) system using a Sun Spare 2 work station receiving information from an EK
500 Simrad echosounder with a huH mounted 38 kHz split beam transducer. The instrument
settings made integrations for each 1.0 n. mHe. The method ofFOOTE et al. (1983) combined
with a Simrad Lobe program was used for the calibration ofthe acoustie system.
Cruising speed during integration was 9.0 knots. The TS-values used were:
TS = 20.0 log 1- 68
TS = 20.0 log 1- 71.9
TS = 19.1 log 1- 74
- cod, haddock, saithe and redfish:
- herring:
- capelin:
3.3 Identification
To identifY acoustie targets, fishing was performed when possible. Trawl sampling was
standard procedure, but the large variations in the bottom topography required alternative
procedures. Pelagic trawling presented few problems, while demersal tfCiwling in some places
was impossible due to the bottom. In some cases jigging was performed to identifY targets. In
total of293 fishing stations, comprising 133 demersal trawl tows, 143 pelagic trawl tows and
17 jigging stations, each lasting for approximately half an hour, were taken during the 1992
survey (Figure 4 and 5).
Demersal trawling was done on bottom ranging from about 25 to about 450 m depth. Pelagic
trawling was made according to echo signals, in discrete depths ranging from the surface to 10
m above the bottom.
The demersal trawl was a 1300 mesh REFA Finnsnes prawn trawl with 35 mm mesh size and
equipped with rubber bobbins. The pelagic trawl was a 10 fathoms Harstad-trawl, with a codend having 10 mm meshes (knot to knot). The trawling speed was 2.0 knots.
For the jigging we used three hand-operated jiggs, each equipped with six hooks.
Length, weight, sex and stage ofmaturity were recorded for each individual fish specimen, and
age determined from otoliths stored in a freezer before being broken and read in laboratory.
3.4 Judging and biomass estimations
Biomass figures were calculated by combining:
i)
ii)
iii)

v)
CPUE-data from the survey trawl catches,
the fish length measurements,
the aged fish material,
the acoustie integrated data,
the judging.

The judging was done at sea and the age read in laboratory. During the judging we tried to
include the listed faetors, in addition to coloured screen prints. All integrated and judged data
were stored on magnetic tapes.
3.5 Age determination, growth and types of otoliths
3.5.1 eod
4.037 otoliths of eod were taken for determination oftype and age. The agening was made by
identification ofannual growth rings (1 hyaline pluss 1 opaque zone equals a year) in the
otoliths, in aeeordanee with procedures used by the Institute ofMarine Research, Bergen. We
discriminated between North-East Arctic and eoastal cod by the method developed by
ROLLEFSEN (1933, 1934).
•
3.5.2 Haddock
A total of3.509 otolihs ofhaddock were sampled. During the age determinations we
attempted to distinguish between coastal and Nort-East Arctic haddoek, as for eod, with no
sucess. The technique for reading age from haddock otoliths was calibrated against procedures
established by the Institute for Marine Research, Bergen (Agotnes, pers.comm.).
4. RESULTS
4.1 Biomass assessments
The total standing biomass in Troms and Finnmark was in 1992 calculated to be 876.000
tonnes (Table 1). More than half ofthis was herring (470.000 tonnes) and about on fifth was
saithe (181.000 tonnes). eod and haddock were found to be about 112.000 and 78.000 tonnes
respectively, and redfish about 25.000 tonnes. As expected wery Httle capelin (10.000 tonnes)
was registered at this time ofthe year.
There were rather large variations between areas in the species distribution between areas and
the composition of species within areas (Table 1). For all species the largest biomass was
found in Finnmark, and except for herring and redfish, the largest fractions were found in
eastern Finnmark, area 03.

4.2 Cod
4.2.1 Classification of stocks by otholiths
Coastal eod dominated over NE Aretic eod in all fjords and sheifareas from Malangen to
Tana. In the fjords coastal eod eonstituted 86 to 98 % (Tables 3-8). In shelf areas the
proportions were Iower, 79 % at Western Troms, 46 % at Sieppen and 73 % at Varanger
(Tables 9 - 11).
4.2.2 Age, length and weight relationships in coastal cod
In some fjords and shelf areas eoastal eod 3 years and younger, and 6 years and oider, were
represented by numbers Iower than 10 specimens. The numbers of4 and 5 year old eoastal
eod was higher than 10 in all areas (Tables 3-11) arid provide the best material for
eomparisons between areas.
The age distributions ofeoastal eod were not uniform. For iristanee, in Malarigen, UlIsfjord
and Lyngen 5 year old eod expressed the strongest mode, while 4 year old eod expressed the
strongest mode in Balsfjord (Tables 3 and 4).
4 year old eod in Malangen, Balsfjord, Ulisjord, LYngt:m and Kvrenangen was on an average
smaller than 45 em, and between 45 and 50 em in fjord farther east (Table 11). In the shelf
areas Vest-Troms, Loppa-Soroya, Räsa, HjeImsoy, Sieppen, 0sthavet and Varangerfjord, the
average lengths of4 year old eoastal eod was larger than 50 em. Thus, there was a gradient in
length inerease from the fjords to the shelf (Figure 7). In 5 year old coast al eod, average
lengths larger than 60 em were reeorded iri Sieppen, 0sthavet and Varanger in eastern
Finnmark, while they were smalier in shelf areas in the western part (Table 11). In general, the
average length at age inereased from west to east along the eoast (Figures 7 arid 8).
The average weight of 4 year old coastal eod was Iarger than 1.2 kg in all sheif areas, arid was
lower than 1.0 kg in all fjords from Malangen to Revsbotn (Table 12). 5 year old eod were on
an average Iarger thari 2.0 kg in Sieppen, 0sthavet and Varanger (Table 12), i.e. the three
eastemmost shelf areas. Thus, as for lengths, there were gradients with inereasing weight
seawards and eastwards.
In the western part ofthe investigated region, the Iength inerements of eoastal eod in
. Malangen and UlIsfjord deereased after reaehing 4 years, in eontrast to eod from Balsfjord arid
Lyngenfjord where the growth rate was sustained after that age (Figure 9). In the eastern-most
fjords the length inerements also deereased after an age of 4 years, but the eod was then Iarger
than in the western fjords. The highest growth rate was reeorded in Varanger (Figtire 9), and
the eoastal eod in this fjord grew at the same rateas eod from eoastal and sheif areas (Figure
10), or NE Aretic eod iri the 0sthavet area and the Barents Sea (Figure 11). Length
inerements of eoastal eod on the sheif was equal to NE Aretie eod in the same areas and in the
Barents Sea, while the Iength inerease for eoastaI eod in fjords were smaller (Figures 11 and
12).

4.2.3 l\'laturity at age
Some ofthe coastal cod started to mature sexually at an age of3 years, both in fjords and in
. shetfareas (table 13). 50% maturity was reached between ages of 4 and 6 years and 100%
maturity between 6 arid 9 years. The differences between areas in the investigated region was
unsysterriatic, with no seaward or eastward gradients.
The percent maturity was not positively related to growth in coastaI eoel, as demoristrated in
Malangen and Ullsfjord where length inerements deereased after an age of4 years (Figure 9).
At that age few eod had matured in Malarigen, while more thein 50% häd matUred in UlIsfjord
(Table 13). In Lyngen where a high growth rate was maintained between 4 lind 6 years (Figure
9), larger proportions of each age group had matured than in Ullsfjord where the groWth was
slower.
•
NE Arctic cod seem to mature at a later age than coastal eod, starting at an age of 4 years in
most areas (table 14). However, the significance ofthis feature may be doubted, beeatise the
number of observations are very few, especially for young fish.
4.2.4 Stock assessment
In 1992, on the eoast from western Troms to eastern Finnmark, we reeorded a total of 88
million eoastal and North-East Aretic eod whieh amounted to a biomass of 112.000 tonnes
(Tables 1, 15 and 16). A fittle more than the half(60.000 tonnes) ofthis biomass was found in
eastern Finnmark (area 03), and approximately 25 % eaeh (25.000 and 27.000 tonnes) in
western Finnmark and Troms, respeetively. Some ofthe fjords, i.e. Varanger, Porsanger,
Revsbotn arid Lyngen, had signifieantly more eod than other fjords. However, there were in
generalIarger amounts ofeod in the shelfareas than in the fjords (Table 15).
4.2.4.1 Abundance and biomass of coastal cod
The proportion of eoastal eorl was 63 mill fish amounting to totaliy 78.000 tonnes (Tables 17
and 18). The spawning stock of eoastal eod was 26 mill fish anlountirig to 52.000 tonnes.
Most of the eoastaI eorl were fOlJlid in the fjords.
4.2.4.2 Abundance and biomass ofNorth-East Arctic cod
A total of25 mill North-East Aretic eod were reeorded and amounted to about 35.000 tonnes
(Tables 21 and 22). Contrary to the eoastal eod the lärger proportion was found in the shelf
.
areas, but they were also abundant in Porsanger and Varanger.

4.3 Haddock
4.3.1 Age, length and weight relationships in haddock
The haddock caught during the investigation were mainly young fish aged 1-4 years (Tables
23 - 27).2 year old haddock dominated in a majority ofthe areas, especially in the eastern
fjords (Table 25). This age group was the only one represented by more than 10 specimens in
all areas.
The average Iength of2 year old haddock was larger than 35 cm in fjords from Malangen to
Revsbotn, Le. in the western part of the investigated region (Table 28). The age-group had
lower average lengths in fjords farther to the east arid in the shelf areas. 3 year old haddock
were on an average longer than 42 cm to the west of Sieppen and srnaller to the east.
The length frequency distributions of2 year old haddock were unimodal and were rather
uniform in shelf areas, displaying a modal maximum in the 30-35 cm class interval. The
Tanafjord had very small 2 year old haddock compared to other fjords (Figtire 14 and 'fable
28).
In sheif areas haddock 4 years and older diffen:id in Iengths but were smaller than haddock
from the Barents Sea, but those were caught 4-6 months Iater (Figure 15). The average
Iengths ofhaddock from fjords in the western part ofthe investigated region were not
markedly different from Barents Sea haddock; hut this was not the ease for haddock in the
fjords farther to the east (Figure 16).
Except for the area named Vest Troms, the average weights of2 year old haddoek were
higher than 004 kg in areas to the west ofHjelmsoy. The 3 year old haddock were heavier than
0.75 kg (Table 29) and they weighed less in Hjehnsoy and areas farther to the east, compared
to the western areas.
4.3.2 l\faturity at age
Exeept for in the Altafjord, the haddoek started to mature as two year old flsh in Revsbotn and
areas farther west (Table 30). Farther east the maturatiori started in 3 or 4 year old fish. 100%
maturity was recorded in 4-6 year old fish, but this observation is based on fewer specimens.
4.3.3 Stock assessment
\Ve reeorded about 174 million haddoek whieh amounted to about 78.000 toeines (Tables 31
and 32). This is equal to the biomass of coastal eod. The ratio between NE Afetic haddoek
and NE Aretic eod was mueh higher than what is found in the Barents Sea. Most ofthe
haddock (42.000 tonnes) was found in Eastern Finnmark (Table 1), whieh is slightly more than
what was found in western Finnmark (19.000) and Trams (17.000 tonnes).

4.4 Saithe, redfish, herring and capelin
4.4.1 Length distributions in saithe
Saithe caught in the fjords were mainly smaller than 50 cm (Figures 17 - 20). Larger saithe
were mainly present in shelf areas from Sleppen and west-wards.
.
4.4.2 Stock assessments of saithe
The total biomass for saithe (181.000 tonnes) was rather evenly distributed between Troms,
western Finnmark and eastern Finnmark (Table 1). Most ofthe biomass was found in shelf
areas.
•
4.4.3 Length distributions in redfish
Length measurements of 4076 redfish (Sebastes sp.) clearly show that the strongest length
mode in the fjord catches decreased from about 40 cm in Malangen to less than 10 cm in
Revsbotn (Figures 21-22). The redfish were also smaller than 40 cm in fjords from Porsanger
to Varanger (Figures 22-23). The length range was larger in the shelfareas (Figures 24-25).
4.4.4 Stock assessments of redfish
The total biomass ofredfish was 25.000 tonnes, with about 15.500 tonnes (60 %) in western
Finnmark 6.000 tonnes in eastern Finnmark and 3.500 tonnes in Trams.
4.4.5 Length distributions in herring
•
The length ofherring varied between 5 and 35 cm, with a rather specific length distribution in
each ofthe areas, and with no systematic geographical trend (Figures 26-30).
4.4.6 Stock assessments of herring
There was a rather large standing stock ofherring - 470.000 tonnes - in the Finnmark and
Troms areas (Table 1). Western Finnmark had about 75 % ofthis biomass (about 355.000
tonnes), while eastern Finnmark had a biomass e10se to 90.000 tonnes. A rather'small biomass
was found in Troms. The highest concentrations were found off north-eastern Varanger,
Magemy, at Revsbotn, Loppa and Silda.

10 .
4.4.7 Length distributions in capelin
The length distributions of eapelin in Porsanger and Varanger were bimodal, with modes
around 9 and 14 em (Figure 31).
4.4.8 Stock assessments of capelin
Approximately 9.800 tonnes of eapelin were recorded, mainly restrieted to eastem Finnmark.
i.e. Varanger, Porsanger and offNordkapp. Qnly small amounts were found in other areas
(Table 1).
5. DISCUSSION
The 1992 survey show that the fjords and shelf areas had considerable fisheries resources.
There were large standing biomasses of cod, haddock, saithe, redfish, herring and eapelin,
amounting to a total of876.000 tonnes from the Russian border to Senja in the Troms
county. However, there were large regional differences.
.
5.1 Cod and haddock
The otolith material clearly indieates the existenee of eoastal eod in eoastal waters outside the
eounties ofTroms and Finnmark, living tagether with North-East Aretic eod. The fjords and
sheltered shelfwaters have larger proportions ofcoastal cod than open shelfwaters. Some of
the fjords may have distinct stocks of eod, like in Malangen where the stationarity of eoastal
eod has been demonstrated by a tagging experiments (ELIASSEN unpubl.).
This investigation clearly indicates regional differences in growth of cod and haddoek eaught
in different areas. These differenees may be due to genotypical differenees due to selfreeruitment within eaeh area, or to phenotypieal modifieation of imported genotypes, due to
partieular ecologieal conditions working on the level of individuals. The available material
does not permit any diseussion of such problems, whieh must be solved by appropriate.
methods in the future.
Most ofthe eod reeorded in 1992 were loeated in the near-shore areas ofthe Barents Sea
shelf, being more abundant there than in the fjords. A large proportion ofthe shelf eod was
identified as eoastal eod with a growth that did not differ markedly from that ofNE Aretie eod
found in the same areas. In fjord areas the eoastal eod was an order of magnitude more
abundant than NE Aretie eod.
The growth in eoastal eod was slower in the fjords than in the shelf areas. Tbis does not seem
to be related to the lower environmental temperatures in fjords, eompared with shelf areas
near by, beeause the growth rates were higher in the cold fjords ofFinnmark than in the
warmer fjords ofTroms.
10
11
Tins may indicate that the feeding coriditions were possibly less favourabie for cod in the
fjords, compared to shelf areas, and better in the east than in thc west. .
;
This is contrary to haddock which grew faster in the western fjords arid shelf areas, thari in
eastern areas. It is diflicult to suggest explanations for these differences. However, bath
capelin and hemng wen~ more abundant inn Finnmark than in Troms, and mighi somehow be
more available to cod than to haddock, for instance when these prey species seck cold water.
There was no systematic dominance of any yearclass of cod, indicating that the recruitment to
..
the fjord stocks has not varied much in the period 1986-91..
However, there was a marked decline of eod aged 7 years and older, in all fjords ancl shelf
areas, exeept in Porsanger where the decline was less pronouncect. We have considered that
the decline could be due to fishing arid natural mortality, but have no iriformation which
supports such
explanation. On the other hand thc fishing pressure in ihe fjords may be
regarded as rather moderate, due to the low quotas which has been set for the eod during the
last years, arid this also applies for the fjords and near coastal area quotas. It seems more likeIy
that the decline was related to sexual maturation, becätise 100% inatUnty was reeorded in
yearclasses 6-8 years old. 1fthis is a valid assumption, it remains to explain where ihe sexiiciIly
mature cod go.
an
During this investigation, the haddock in the fjords and the shelf areas eonsisted mostly of
immature fish. At the age of 100% sexual maturity, Le. 4-6 years, thc abundance of older fish
declined markedly. In the exploited stock ofNE Arctic haddock, 4 arid 8 year old fish display
modes in the age frequency distribution (ANON. 1992), but these yearclasses were absent in
most ofthc sampIes from the investigated areas. This is
important observation ofno
covariation of the yearelasses between the Barents Sea arid thc near-shofe shelf arid fjord
areas. The sexually mature fish may have stayed elsewhere in September when thc
,
investigation was made. However, they mayas weIl have been present arid integrated in our
acousiic methods, but eseaped from OUf sarnpling gear.
an
Ideritification arid aeousiic integration offlsh in fjords and near-shore shelfareas have some
major limitations:
•
i) Sampling by pelagic and clemersal trawling may be difflcult e10se to or at the bottom
alorig steep slopes frequently met with in fjords and sheltered sheIf areas. Fishing with trawls
was mostly done over level bottom in the median paris offjord basins and iroughs on the
shelf.
ii) The aeoutic method has some weaknesses regarding presize registratians along the
slopes due to the side-Iobes and the blind zones.
NE Afctic eod aged i -3 years was in general weakly represented in the investigated area, in
relation to 4 and 5 year old fish whieh were sexually maturirig yearclasses, probably
terininating with 100% matunty ai an age of 6-7 years. ANON (1992) reports that 1-3 year .
old NE Arctie eod reeorded in the Norwegian aeoustie surveys and the Rtissian aeoustie trawl
surveys are not iess mimerous than 4 and 5 year old fish. Thus, the investigated areas were
probably not nursery habitats for the youngest NE Arctie eorl when the investigation was
made. On the other harid, the eoastal eod mirigled with NE Areiie in eoastal areas, to a larger
extent in near-shore shelf ares than in the fjords.
11
12
5.2 Saithe, redfish, herring and capelin
Herring constituted the dominant biomass in Trams and Finnmar~ amounting to more than 50
% ofthe total biomass. The populations found in different areas were not uniform, as the size
differences indicate age frequency differences. However, it may be possible that schools
selecting different size compositions have been present in most fjords and that the sampling
has been rather randorn, selecting different size groups in different areas. All the herring
prabably belong to the stock ofNorwegian spring spawners whichhas it northem limit of
distribution in the southem Barents Sea. The presence and distribution ofherring in this area
may have influenced the distribution of predators Iike cod, saithe and haddock. Thus, absence
of a different distribution pattern ofherring in other years, may also cause a different
distribution ofpredators.
Saithe constituted the second largest biomass, larger than that of cod, both in Troms, western
and eastem Finnmark. Most ofit was was fish smaller than 50 crn, i.e. prabablyadolescent
fish.
The redfish presented in this investigation is a mixture ofthree Sebastes species, S. marinus, S.
mentella and S. viviparus. Thus, it is difficult to make any comments on the stock structures.
•
Capelin occurred mostly in the eastem areas and consisted ofboth a fraction of small
immature fish and larger fish which probably would enter the spawning stock in 1993.
In conclusion, it may be stated that the two counties ofTrams and Finnmark in 1992 had
considerable resources bound to their coastal waters.
