Growth of the Barents Sea capelin compared to stock size and geographical distribution
(ICES CM Documents;1986/H:38, Working paper, 1986)The growth of individual capelin in the Barents Sea stock was analysed in relation to the geographical distribution and size of the stock in the feeding season, and the density of fish in the feeding area. The growth ... -
Growth patterns in the North Sea and western mackerel in Norwegian catches 1960- 85
(ICES CM Documents;1989/H:21, Working paper, 1989)Length, weight and age in random samples from Norwegian catches of' mackerel from 1960 to 1985 have been reviewed. A standard growth curve was constructed by applying a modified von Bertalanffy equation to all data. The ... -

How to correct fish density estimates for extinction
(ICES CM Documents;1990/B:24, Working paper, 1990)There have been many experimental studies on acoustic shadowing, but once the effect is quantified, how is the compensation to be effected? This work shows how, through postprocessing of stored time series, containing ... -
ICES coordinated acoustic survey of ICES divisions IIIa, IVa, IVb and VIa (North) 2003 Results
(ICES CM Documents;2004/R:32, Working paper, 2004)Six surveys were carried out during late June and July covering most of the continental shelf north of 52°N in the North Sea and to the west of Scotland to a northern limit of 62°N. The eastern edge of the survey area was ... -
Identification of fish communities in the Barents Sea: Is there a faunal discontinuity across the Polar Front?
(ICES CM Documents;2002/L:17, Working paper, 2002)Fish species inhabiting the Barents Sea display great seasonal and between-year variation in abundance and distribution. This study describes the assemblages and distributions of fish species in the south-western part of ... -
In situ target strength observations on haddock
(ICES CM Documents;1986/B:39, Working paper, 1986)In situ target strength measurements of ideally resolved haddock have been made using the ES-400 split-beam echo sounder. The measurements are compared with the mean target strength obtained simultaneously by counting ... -
Incorporating experimentally derived estimates of survey trawl catchability into the stock assessment process
(ICES CM Documents;1997/W:5, Working paper, 1997)During the course of the April, 1996, meeting of the Fishing Technology and Fish Behavior Working Group it became clear to many that the methodology for experimentally estimating the catchability of survey trawls might ... -

Influence of climate on recruitment and migration of fish stocks in the North Sea
(ICES CM Documents;1991/H:12, Working paper, 1991)For several decades one of the prime targets within fishery science has been to be able to understand and explain the great variability in the success of survival from egg to mature fish. One of the reasons why such effort ... -
