Growth of capelin in relation to zooplankton biomass in the Barents Sea
Gjøsæter, Harald; Skjoldal, Hein Rune; Hassel, Arne (ICES CM Documents;1995/P:5, Working paper, 1995)Growth of capelin in the Barents Sea stock has been found to vary considerably both between years and between different parts of the distribution area. The aim of this paper is to compare such growth variations with ... -
Impact of grazin from capelin (Mallotus villosus) on zooplankton: a case study in the northern Barents Sea in August 1985
Hassel, Arne; Skjoldal, Hein Rune; Gjøsæter, Harald; Loeng, Harald; Omli, Lena (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" ... -

Seasonal development of plankton in the Barents Sea: A conceptual model
Rey, Francisco; Skjoldal, Hein Rune; Hassel, Arne (Working paper, 1987)Capelin (Mallotus villosus) is a small salmonid fish that forms the basis of one of the most important fisheries in the Barents Sea. Relatively large variations in growth of capelin prompted ecological investigations ...
