(ICES CM Documents;1997/CC:15, Working paper, 1997)The Norwegian Sea is an important feeding area for blue whiting in the Northeast Atlantic. The adult blue whiting migrates into the Norwegian Sea after spawning along the continental slope west of The British Isles. A ... -
Changes in abundance and distribution of the Barents Sea long rough dab, hippoglossoides platessoides (Fabricius) during the period 1980- 1992
(ICES CM Documents;1993/G:36, Working paper, 1993)Abundance and biomass of long rough dab in tha Barents Sea and adjacent waters were assessed from bottom trawl survey data from research surveys by Norway and Russia, during the period 1980- 1992. Although there was no ... -
Changes on horse mackerel (Trachurus trachurus) catch distribution in the Northeast Atlantic
(ICES CM Documents;1996/S:26, Working paper, 1996)The distributions of international commercial catch data were mapped by ICES rectangle and quarter from 1983-1994. These indicate a northward expansion of horse mackerel distribution in the Northeast Atlantic since 1987. ... -
Data on the 1983 year class of Norwegian spring spawning herring from the period June 1985 -August 1986
(ICES CM Documents;1986/H:19, Working paper, 1986)This paper considers the distribution, growth and migration of the 1983 year class of Norwegian spring spawning herring. There are, at present, two geographical components of this year class, one component with a nursery ... -
Diet of polar cod, Boreogadus saida, in the Barents Sea related to fish size and geographical distribution
(ICES CM Documents;1990/G:48, Working paper, 1990)Polar cod stomachs collected during autumn of 1986-1988 in the Barents Sea were analysed. The results indicated that polar cod is an opportunistic feeder, and that the observed changes in feeding pattern from one region ... -
Discrimnation of herring populations in a northern Norwegian fjord: genetic and biological aspects
(ICES CM Documents;1986/H:63, Working paper, 1986)From a trawl survey in a fjord system in northern Norway, it has been possible to separate catches of herring into two distinct groups characterized by different number of vertebrae (VS). Low- vertebral herring (VS = ... -
Distribution and growth of blue whiting in the north-east Atlantic
(ICES CM Documents;1990/H:14, Working paper, 1990)The distribution pattern of the blue whiting spawning stock has gradually changed in recent years, and concentrations are recorded more offshore and more to the south than before. The activity of the fleet with its ... -
Distribution and growth of capelin in the Barents Sea in relation to water temperature in the period 1974 to 1983
(ICES CM Documents;1984/GEN:16, Working paper, 1984)The variation in the distribution of the different age-groups of capelin in the Barents Sea were studied in relation to temperature variation in the period 1974 to 1983. In addition, growth of the capelin were compared ... -
Distribution and sedimentation of radionuclides in the Barents Sea
(ICES CM Documents;1995/Mini:11, Working paper, 1995)Analysis of sediment samples for cesium-137 from a wide range of positions have demonstrated an uneven distribution. The causes, pathways and the possible origin of the radionuclide are discussed. The importance of ... -
Distribution of bioluminescence and plankton in a deep Norwegian fjord measured using an ISIT camera and the Digital Underwater Video Profiler
(ICES CM documents;2007/F:02, Working paper, 2007)Bioluminescence and plankton profiles were obtained using a downward-looking ISIT low-light camera and the Underwater Video Profiler system in Sognefjord, Norway. The profiling systems were lowered by CTD wire and recorded ... -
Distribution of Norwegian spring-spawning herring and mackerel in the Norwegian Sea in late summer, 1991
(ICES CM Documents;1992/H:13, Working paper, 1992)A pairtrawl survey was carried out in the Norwegian Sea during July - August 1991 to map the distribution of pelagic fish. Herring were caught throughout most of the surveyed area, with the largest concentrations observed ... -
Distribution, drift and condition of herring larvae off western Norway in 1985
(ICES CM Documents;1986/H:39, Working paper, 1986)The recruitment to the Norwegian spring-spawning herring have during the last twenty years been on a very low level. However, the size of the spawning stock has increased in recent years and in 1983 a rich year class ... -
Factors affecting the distribution of wrasses in a fjord system: analysis by generalised linear models
(ICES CM Documents;2000/N:31, Working paper, 2000)Background: Generalised linear models (GLMs, see McCullagh & Nelder 1989) form a modern, flexible and unified approach to statistical modelling. GLMs are of particular value to the analysis of data from ecological surveys, ... -
Field studies of harp seal (Phoca Groenlandica) distribution and feeding ecology in the Barents Sea in september 1990
(ICES CM Documents;1991/N:3, Working paper, 1991)The harp seal Phoca groenlandica is the most abundant seal species in the Barents Sea, and it may be a significant predator on other marine resources in this area. In order to evaluate the ecological role of harp seals, ... -
