On a monthly basis the sprat population on the, Belgian coas·r ",as stuclied

Herring~
(S.IT. Tibbo)
Total landings of the' mobile herring fleet in Newfo~dland i~ 1971-1972
,,,ere about 50 000' metrie tons, about 'one' quarter of 1;he record 1969-1970
landings. The large deerease is attributed partly io severe ice and
ueather conditions, but in addition there has, been no subs1;antial' recrtlitment recently to bolster the diminishing'south\Jest Newfoundland
her~ing stocks.
' '
,.
,
Mobile fleet landings in the Gulf of St Lawrence ,and ·Chedabucto Bay in
1972 were 33 902 and 26 500 metrie tons, only about 26% and 5~; respeetively of the 1971 landings. The New Brunswiek weir and purse seine
fishery landed almost 4.5 times as many herring (56 000 tons) as in 1971.
South\'lest Nova Seotia landings increased by 25~& to 62 000 tons (excluding
gill net catches estimated to be betueen 5 000 -10 000 tons).

Tag returns frqm an experiment in northuestern Neufoundland oeeurrecl' in
the southerri" p1:trt of the Gulf of St Laurence ,and in southuestern
Ne'lJTf oundland.
Studies of biological characteristics and tag returns \vi thin 'JYortllrie .. 13ay
support the hypothesis that the spring-spa\q,ning herring in Fortune
Bay, ,southern Ne,,,foundland, are a rela t i vely discrete stock vith sharp._
differenees from the spring-spa''lning component westlJard'along the south
coast of Newfoundland.
.
Studies of infestatiön levels of larval nematodes (Anisaki~)..in~eri~ng
show substantial differenees betl1een the northern Scotian Shelf'snd the
southwest Ne\Jfoundland-sonthern Gulf of St Lal'Trence stock 'comple"C.
The herring programme at the St Andrews Station \jas directed largely towards obtaining ~isheries information and providing scientifc advice required to formulate management proposals. Research uas directec1 to +_10
problems of stock identifieation anel larval movements in the Bay cf
- 2 -
Fundy. Detailed biological data (length, "eight, age, sex and
maturity) were collected from over 20 000 herring and over 6 800
herring were used for meristic studies (vertebrae and dorsal, pectoral
and anal fin ray counts).
Two additional enzyme systems have been added to those already used as
genetic markers to delineate herring stocks : leucine aminopeptidase and
glucose-6-phosphate dehydrogenase.
Genotypic and phenotypic studies of 56 herring population samples indicate
that herring stocks from Europe to Newfoundland to Virginia all have a
common gene pool for muscle and heart enzymes. Genetically based blood
protein and enzyme systems, however, may be able to isolate herring
populations by biochemical means.
In a feeding study, raw or hydrogenated herring oil had no adverse
effect on the hearts of weaned rats after 4 weeks as a graduated replacement for other fats. Analytical methodS vTere also devcloped for
the detailed study of the fatty acid composition of hydrogenated marine
oils in edible oil products.
lJIackerel,
A good 1967 year class resulted in a large increase in mackerel abundance in Newfoundland and Labrador coastal areas.
In August 1 450 mackerel Were tagged in northeastern Newfoundland coastal waters. A subsequent recapture in December by a Polish vessel fishing
on the southernpart of Georges Bank indicates long distance migration.
Siudies aimed at increasing thc market potential for Atlantic species .
of fatty fish are now under ,vay. These include an investigation of the
mechanism by which rancidity develops in the dark and light muscle of
mackerel and its affect on the quality and shelf-life of fresh, frozen
and processed mackerel products, plus an investigation cf the catalytic
effects of lipases and lipoxidases and the role of natural and added
antioxidants.
Capelin
Exploratory fishing with midwater trawlßrs and purse seiners in the
Grand Bank, eastern Newfoundland, and Labrador regions indicated.that
an annual capelin fishery is possible during the offshore spavrning
season in summer and in the post-spm'rning period in the northern areas.
Barracudina
Barracudina oils and waxes have the same chemical qualities and could
rep1ace sperm whale oil required by the cosmetic, luxury candle and
high pressure lubricant industries. Barracudina are not utilised
at the present time and are relatively unknovrn to fishermen because
they appear at the mid-water leveluhere trawling is relat'ively new and
still experimental.
Substantial barracudina resources have been found
in the Gulf of St Lawrence.

Sampling
Statistics collection and sampling of the catches from the Scottish herring
fisheries was continued in 1972 (see Table 1).
SampIes of herring from the Scottish fisheries were examined for the incideI~
and intensity of infection by Anisakis sp.
T?ß~ing
Tagging of herring from chartered ~~d research vessel catches during 1972 is
summarised in Table 2. During 1972 there were two further returns from tho
west const tagging in Pebruary-March 1971 and 29 from the west coast tagging
in September 1971. All were recaptured on the west coast. Prom the June
1971 tagging around Shetland, there have been 20 more returns from the Shetland area and one from the west coast.
Roooareh Vessel Surveys
Tbe surveys carried out by Scottish research vessels are shown in Table 3.
other Research Activities
Experimental studies were begun to investigate the efrects of a number
of to~ic pollutants on the development, growth and survival of herring eggs
and larvao.

Tagging or herring rrom chartered a.~d research veesel catches during 1972 is
summarised in Table 2. During 1972 there were two further returns from the
west coast tagging in February-March 1971 and 29 from the west coast tagging
in September 1971. All were recaptured on the west coast. From the June
1971 tagging' around Shet1and, there have been 20 more returns rrom the Shetland area and one from the west coast.

Other Research Aotivities
Ex~erimenta1 studies ware begun to investigate the effects of a number

Col1ection of commercia1 statistics and samp1ing of catches of the
Scottish sprat fisheries was continued in 1972 (Table 4). Weight
data were recorded on a routine basis.
Research Vesse1 Surveys
Two echosounder and midwater traw1ing surveys were conducted for sprat in
the Moray Firth and an egg and larval survey off the Scottish west coast
in June (Tab1e 5) •

Sampling of the Scottish commercial mackerel catches was continued in

Studies were carried out in 1972 on the abundanoe, distribution and growth
of immature mackerel in the North Sea and on the maturation cycle and back
calculated growth•

In 1972 the Pelagic Fish Laboratory of PllrRO (Polar Research Institute)
continued invcstigations on thc biology of herring in thc Norwegian, Darents
and White Seas as weIl ns on the biology of blue whiting in the Norwceian

Tbe North-East At1antie Laboratory of the At1antie Resea~eh lnotitutc of

The eollection of materials was carried out in ihc'eourse of cruises from

biology, distribution and abundance dynamics of horsemackerel, mackerel
and Norway pout were continued. The method of ~orecasting the atmospheric
pressure fields ovar the North Sea was worked out.
Complex of investigations accompanied by oceanologieal observations on
peeuliarities of distribution, biology and relative abundanee of horsemackerel and mackerel year classes was earried out from December to May
to the west ef the Eritish Isles and in the Eay of Eiseay.
Conditions and efficiency of reproduetion, larval and YOt~ distribution
and eeology were studied in the eastern and northern Ealtic Sea, the
Gulf of Riga and the Gulf ef Finland.
State,distribution.and structure of Spring and Autumnherring and sprat
stocks; and stock state of populations were investigated. Materials
for estimation of the effect of fishery, and of predators Ceod) on the
state of sprat and herring stocks were eollected.
.
The Institute of Animal Morphology of theAcademy of Seiences eondueted
investigations on the intercorrelation between the 'ihite Sea and Murman
speeies of herring. Meristic features of larvae and fingerlings of different
stocks of the White Sea herring were investigated and differences between
them were clarified•
