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, ... -
Fish communities on the slop of the eastern Norwegian Sea
(ICES CM Documents;1998/O:30, Working paper, 1998)Bortom trawl data from the depth interval 300-2050 m on the slope off Norway were analysed to study distribution of fish biomass and the associated species assemblages. It is hypothesised that the pronounced hydrographic ... -

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 ... -

Haneskjellet, Chlamys islandica (O. F. Müller) og dets utbredelse i noen nordnorske fjorder
(Fisken og havet;1962 - Nr. 3, Journal article, 1962)The distribution in northern Norway of the Iceland scallop, Chlamys islandica (O. F. Müller) has been mapped (Fig.s 3-7). The species is mostly found in the inner of fjords having one or two sills, 3-15 m deep ... -

Herring larvae (Clupea harengus) investigations in the Skagerrak area, December 1987 to March 1988. A preliminary report
(ICES CM Documents;1988/H:20, Working paper, 1988)From December 1987 to March 1988 two transects, Torungen - Hirtshals and Oksøy - Hanstholm, were performed once a month for sampling of herring larvae. The gear used was a 9 feet Isaac-Kid Midwater trawl sampling in the ... -
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 ... -
Impact of grazin from capelin (Mallotus villosus) on zooplankton: a case study in the northern Barents Sea in August 1985
(ICES CM Documents;1991/L:62, Working paper, 1991)The distribution of capelin was mapped in the area east of Hopen. Zooplankton was sampled with Juday net and 1m^2 MOCNESS sampler, and analyzed with respect to hydrography and capelin abundance. The capelin "front" ... -
Incongruence between the distribution of a common coral reef sponge and photosynthesis
(Journal article; Peer reviewed, 2011-02-10)Symbiosis between coral reef fauna and microorganisms drives the growth, maintenance and diversity of coral reef habitats. Sponges, a key faunal component of coral reefs, form complex symbiotic relationships with ... -
Individual based spatial models with evolved fish behaviour
(ICES CM Documents;1998/J:16, Working paper, 1998)Due to spatial heterogeneity, the survival and growth of fishes depend upon their habitat. For mobile pelagic fishes, it hence becomes important to analyse the factors responsible for spatial dynamics in order to understand ... -
Influence of sea temperature on herring distribution and migration in the Norwegian Sea in April 1997
(ICES CM Documents;1999/M:3, Working paper, 1999)After spawning at the west coast of Norway, the Norwegian spring spawning herring migrates northwestwards into the Norwegian Sea to feed in early April. The herring enters areas with distinct oceanographic features both ... -
Initial collateral measurements of some properties of Calanus finmarchicus
(ICES CM Documents;1996/L:21, Working paper, 1996)In general, acoustic quantification of zooplankton such as Calanus finmarchicus requires the use of models, among other reasons, to aid in the interpretations of data collected on animals whose scattering properties change ... -
