Catch statistics and life history of shrimp, Pandalus borealis, in the Jan Mayen area
(ICES CM Documents;1996/K:11, Working paper, 1996)The Norwegian shrimp (Pandalus borealis) fisheries in the Jan Mayen area in the North East Atlantic started in 1974. The catches reached 2000 tons in 1985. Since 1986 the catches decreased, but lately they have increased ... -

Causes of variation in carcass traits of Atlantic salmon (Salmo salar)
(ICES CM Documents;1984/F:25, Working paper, 1984)The aim of the present study was to reveal causes of variation in carcass traits of farmed Atlantic salmon (Salmo salar). During slaughtering of one year class Atlantic salmon, composed of half sib and full sib groups, ... -

Change in Fish Community Structure in the Barents Sea
(Journal article; Peer reviewed, 2013-04-29)Change in oceanographic conditions causes structural alterations in marine fish communities, but this effect may go undetected as most monitoring programs until recently mainly have focused on oceanography and commercial ... -
Changes in acoustic abundance - a signal indicatior for stock dynamics for cod (Gadus morhua)
(ICES CM documents, Working paper, 1999)To be able to take the proper and timely management actions, it is crucial to reliably defect major changes in trends of fish stock abundance. For the assessment of Northeast Arctic cod, the Norwegian bottom trawl survey ... -
Changes in growth of Northeast Arctic cod in relation to food consumption in 1984-1988
(ICES Marine Science Symposia, Journal article; Peer reviewed, 1991)From 1984 to 1988 the average weight of cod (Gadus morhun) by age group in the Northeast Arctic stock was reduced by about 60% in most age groups. During the same period, the estimated individual food consumption by age ... -
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 ... -
Changes in the dynamics of the Norwegian mackerel purse seine fishery – does it influence the representativeness of the reference fleet data?
(ICES CM documents;2008 / I:13, Working paper, 2008)The last three years, the peak period and the fishing area of the Norwegian mackerel purse seine fishery has changed considerably due to market situations. The Norwegian reference fleet was established to get better and ... -
Changes in the relationship between sea temperature and recruitment of cod, haddock and herring in the Barents Sea
(Journal article; Peer reviewed, 2013-06-14)Cod, haddock and herring in the Barents Sea have strongly variable recruitment. For these three stocks, earlier studies have suggested a high correlation between their recruitment and a positive relationship between high ... -
Characterization and expression levels of protease enzymes at different developmental stages of Siamese fighting fish (Betta splendens Regan, 1910)
(Journal article; Peer reviewed, 2010-05)Characterization of total proteases, trypsin and chymotrypsin were performed at pH 2 12 and temperatures 20-80°C in three life stages of Siamese fighting fish (Betta splendens Regan, 1910). At least fourteen protease ... -
Cleaning symbiosis between wrasses (Labridae) and lice infested salmon (Salmo salar) in mariculture
(ICES CM Documents;1988/F:17, Working paper, 1988)Epidemic infestation by the crustacean ectoparasitic salmon lice (Lepeophteirus salmonis) is a major problem in marine salmon farming. Cleaning symbiosis between different labrid species and lice infested salmon is ... -
Climate-induced synchronous regime shifts along environmental and diversity gradients in Baltic Sea sub-systems

Climatic effects filtered through the food web affect the dynamics of Arcto-Norwegian cod
(ICES CM documents, Working paper, 2005)The world's largest cod stock, the Arcto-Norwegian cod (a.k.a. North-East Arctic cod), is heavily influenced by temperature in two ways: First, cod recruitment tends to be high when Barents Sea temperature in the spawning ... -

A closed life-cycle model for Northeast Arctic cod
(ICES CM documents, Working paper, 2004)For Northeast Arctic cod (Gadus morhua), there is much knowledge available concerning the main population dynamics processes (growth, maturation, fecundity, recruitment, natural mortality, fishing mortality). This knowledge ... -
Coastal releases of Atlantic salmon, a new model for salmon ranching in Norway
(ICES CM Documents;1991/M:38, Working paper, 1991)The present project is launched within the frame of a 7 year government funded programme to establish an additional livelihood for the coastal regions. The aim of the study is, through controlled experiments, to find ... -
