Abundance and mortality of Northeast Arctic cod and haddock during their first years of life
(ICES CM Documents;2010/C:04, Working paper, 2010)For Northeast Arctic cod and haddock in the Barents Sea, long time series of year-class abundance are available at several stages before they recruit to the fishery, i. e. before they reach age 3. Several studies have ... -
Barents Sea Ecosystem Resilience under global environmental change 2010-2013
(ICES CM Documents;2010/Q:27, Working paper, 2010) -
Behavioural rhythm of cod during migration in the Barents Sea
(ICES CM Documents;2000/K:34, Working paper, 2000)To assess fish abundance by direct methods and to understand and model species interaction, it is important to have proper knowledge about behavioural patterns. Patterns in vertical distribution might strongly affect ... -
Changes in the Barents Sea fish community induced by environmental change and fishery
(ICES CM documents;2009/ F:05, Working paper, 2009)A spatio-temporal analysis of Barents Sea survey data from the deeper parts of the Barents Sea shows a sudden change in fish community structure and abundance taking place in the mid 1980s and 1990s. The change in fish ... -
Climatic variations in the Barents Sea during the 1970`s

Contaminants in the Barents Sea ecosystem
(ICES CM Documents;1995/Mini:9, Working paper, 1995)A baseline study of contaminants in fish and sediments from the Barents Sea was carried out by Institute of Marine Research (IMR) as a part of the Arctic Monitoring and Assessment Programme, AMAP. Sediment samples from ... -
Eastern Scotian Shelf and Barents Sea intercomparison: climate fluctuations, human impact, and system resilience

Estimates of stock size of cod, haddock, redfish and greenland halibut in the Barents Sea and the Svalbard area, autumn 1987
(ICES CM Documents;1988/G:44, Working paper, 1988)Combined acoustic and bottom trawl survey for cod and haddock were carried out in the Svalbard area together with an acoustic survey in the Barents Sea in autumn 1987. The abundance index in numbers of cod continued ... -
Fisheries management in the Barents Sea
(ICES CM Documents;1999/Q:1, Working paper, 1999)The fisheries in the Barents Sea are of very high importance to the region. Most of the fish stocks are shared by Norway and Russia and joint management decisions are taken by The Joint Norwegian-Russian Fisheries ... -
Fisheries-induced evolution in Northeast Arctic cod
(ICES CM documents;2005/AA:16, Working paper, 2005)We explore the evolutionary effects of fisheries on North-East Arctic (NEA) cod. It has earlier been shown that fisheries can change the cod’s age and size at maturation in two ways: first, by reducing the biomass, which ... -
Growth of 0-group fish in relation to temperature conditions in the Barents Sea during the period 1965- 1989
(ICES CM Documents;1990/G:49, Working paper, 1990)Since 1965 the International 0-group fish survey has been carried out in the Barents Sea during late August and early September. The main purpose is to determine the year-class strength of some commercial fish species ... -
Growth of Polar cod (Boreogadus saida) in the Barents Sea
(ICES CM Documents;1990/G:47, Working paper, 1990)Observed length-at-age, and backcalculated lengths based on otolith measurements, from samples of polar cod collected in the Barents Sea in autumn of 1987 to 1989, were analysed. An increase in individual length growth ... -
Growth of the Barents Sea capelin of the year-classes 1967-70
(ICES CM Documents;1977/H:39, Working paper, 1977)Otoliths of the 1967-70 year-classes of the Barents Sea capelin have been analyzed. For otoliths with radius < 0,74 mm there was a close, linear relation between fish length and otolith radia. For larger otoliths the ... -
Identifying particularly valuable and vulnerable areas: a key tool for the integrated management plans for the Barents Sea and Norwegian Sea.
(ICES CM documents;2008/E:14, Working paper, 2008)In 2006 Norway implemented an integrated and ecosystem-based management plan for the Barents Sea, and is currently developing a similar plan for the Norwegian sea. Norway aims to have such plans for all sea areas under ... -
Interannual variations in the liver condition index of cod as an indicator of temperature and feeding conditions in the Barents Sea
(ICES CM Documents;2001/V:31, Working paper, 2001)Background: Northeast Arctic cod, inhabiting the edge of the species area, experience variable environmental conditions and feeding resources, one of the main of them is capelin. Lipids are an important biochemical link ... -
