Growth rates and age distributions of capelin (Mallotus villosus) larvae in the Barents Sea investigated by otolith increment analysis
(ICES CM documents, Working paper, 2004)In order to investigate age distributions and growth rates, otoliths from capelin larvae collected from the Barents Sea during the summers 2001-2003 were analysed using otolith microstructure analysis. Stations were ... -
Growth rates in cultured common wolffish (Anarhicahas lupus) and spotted wolffish (A. minor)
(ICES CM Documents;1990/F:2, Working paper, 1990)Field caught common wolffish (Anarhichas lupus) and spotted wolffish (A. minor) have been raised from fry on dry pellets. The two species have experienced annual fluctuations in temperature between 6 and 12 °C and the ... -
Growth, recruitment and mortality of Pandalus borealis (Krøyer), in Balsefjord, Northern Norway
(ICES CM Documents;1976/K:31, Working paper, 1976)A population study of the deep sea prawn started in autumn 1975. Eight months were sampled until July 1976. The von Bertalanffy growth parameters were estimated from mean carapace length of certain year classes, excluding ... -

Habitat selection and competition amongst 0-group gadidae off Mid-Norway
(Working paper, 1988)Juvenile gadids and other co-occurring fishes were collected during August in the years 1981 to 1983 at the Møre coast (Mid-Norway). The gears used were pelagic trawl, bottom trawl, Danish seine and beach seine. All species ... -
Haddock avoidance reactions during trawling
(ICES CM Documents;1986/B:36, Working paper, 1986)Fish reaction to the whole trawling operation was studied using a stationary echo sounder-system observing the fish in front of the vessel and during trawl passage. Strong avoidance reactions were observed on haddock, ... -

Harp seal (Phoca Groenlandica) invasions in north Norwegian coastal waters: A preliminary report on age composition and feeding habits
(ICES CM Documents;1990/N:6, Working paper, 1990)Since 1978 large numbers of harp seals (Phoca groenlandica) have invaded areas of North Norway in winter and spring. In 1987 and 1988 dramatic increases occurred both in magnitude and geographic extent of these seal ... -
Harvest control rules and changing productivity: the working example of North Sea herring
(ICES CM documents, Working paper, 2006)North Sea herring is managed by the EU and Norway through a harvest control rule where target fishing mortalities are changed if the estimated SSB falls below a trigger biomass million tonnes). This management agreement ... -
