Recruitment of wild and artificially reared cod (Gadus morhua L.) to the local spawning stock
(ICES CM Documents;1987/F:27, Working paper, 1987)A stock enhancement study of coastal cod was initiated in 1983, when 19,002 artificially reared cod fry were tagged and released in the Austevoll region in western Norway. As a part of this program, 3,946 cod fry were ... -

Recruitment variability in Norwegian spring-spawning herring (Clupea harengus L.): the effect of temperature in larval drift trajectories
(ICES CM documents, Working paper, 2000)During late winter, the Norwegian spring-pawning (NSS) herring migrate southward along the Norwegian coast to spawn in March-April. The larvae drift northwards in the Norwegian coastal current during their first months and ... -
Red king crab (Paralithodes camtschaticus) in the Barents Sea
(IMR/PINRO Joint Report Series, Conference object, 2004)The distribution range of the red king crab in the Barents Sea continues to expand in eastern, northern and western directions. In autumn 2002 the recruitment to the legal size stock was good in the eastern part of the ... -

Reduced bycatch of red king crab (Paralithodes camtschatica) in the cod gillnet fisheries in northern Norway: Fishing trials with norsel mounted gillnets
(ICES CM documents, Working paper, 2000)Bycatch of red king crab (Paralithodes camtschatica) in stationary fishing gears, q&ally gillnets, is an increasing problem to the inshore fishermen in the northern part of Norway (Finnmark county). The results are large ... -
Reduced oxygen concentrations in herring wintering areas
(ICES CM Documents;1992/H:16, Working paper, 1992)Since 1987 the major part of the adult Norwegian spring spawning herring stock has been wintering in the Ofotfjord and the Tysfjord, two tributaries to the Vestfjord in northern Norway. The herring enter the fjords in ... -
Reduction of fish bycatch in shrimp trawl using a solid separator grid in the aft belly
(ICES CM documents;1990/B:47, Working paper, 1990)During 1989-90 a new concept to avoid bycatch of fish in shrimp trawl has been developed in Norway. The system consists of an aluminium grid, 0.6 - 1.0 m wide and 1.3 - l.5 m long, with bars spaced 19 mm. The grid is ... -
Regional dynamics of Calanus in the Norwegian Sea in response to ocean climate in 1997
(ICES CM Documents;2000/M:20, Working paper, 2000)A coupled 3D hydrodynamic and ecological model has been set up for the Norwegian Sea (i.e. SINMOD). The hydrodynamic model uses the z-coordinates in the vertical direction. The horizontal grid point distance is 6.67 km ... -
