Kartlegging av gytefeltene for norsk-arktisk torsk i Nord-Norge og beregning av eggproduksjonen i årene 1983-1985
(Fisken og havet, Research report, 1987)The population fecundity of Northeast-arctic cod were computed for the years 1983, 1984 and 1985. Repeated and detailed egg surveys were conducted at the spawning sites in Lofoten and along the coast of Troms and ... -
Kartlegging av gyteplasser og sonderende oksygenmålinger i utvalgte fjorder i Risør, Tvedestrand og Lillesand kommune
(Fisken og havet, Research report, 2000)This pilot project was initiated to compile and map old fishermen's local information on spawning areas of cod and other commercial fishes along the Norwegian Skagerrak Coast. Interviews revealed that fishermen had good ... -

Kysttorskmerkinger 1964
(Fisken og havet;1964 - Nr. 6, Journal article, 1964)Cod tagged in February 1964 outside Bergen, and at Møre was during February-March in the tagging year recaptured north and south of the tagging localities (Fig. 1 and 3). The returns from the tagging experiments in Solund ... -
Landscape dynamics and predator-prey interactions in marine environments
(ICES CM documents, Working paper, 2004)In several sub-arctic marine ecosystems of the North Atlantic capelin are the primary prey item for cod, and the trophic interaction between capelin and cod is a central energetic pathway. However, in the North Pacific ... -
Large-scale rearing of cod fry on the natural food production in enclosed pond
(Flødevigen rapportserie, Research report, 1983-06) -
Larval and small juvenile cod Gadus morhua concentrated in the highly productive areas of a shelf break front
(Journal article; Peer reviewed, 1995-09-14)The early life of cod was studied during a survey programme covering the northeastern North Sea, the Skagerrak and the Kattegat in May 1992. Our aim was to asses the interrelated effects of physical and biological factors ... -
Limiting inter-annual variation in total allowable catch strategies. An application to ICES roundfish stocks
(ICES CM Documents;2003/X:7, Working paper, 2003)This study evaluated through simulation management strategy that stabilise catch levels by setting bounds on the inter-annual variability in Total Allowable Catches (TACs). An integrated modelling approach was used, which ... -
Linking tagging technology and molecular genetics to gain insight in the spatial dynamics of two stocks of cod in Northeast Atlantic waters
(ICES CM documents, Working paper, 2006)The Northeast Arctic cod (Gadus morhua L.: NEAC) is thought to be the most abundant cod stock in the North Atlantic, while the catches of the partially co-occurring Norwegian coastal cod (NCC) stocks have dramatically ... -
Liver energy, atresia and oocyte stage influence fecundity regulation in Northeast Arctic cod
(Journal article; Peer reviewed, 2010-04-08)Marine ecosystems are changing; global warming-induced increases in water temperatures and fishing have caused truncated age structures and small sizes at maturity in many stocks. This may affect both populations’ total ... -
Lofotteina: Uttesting for bruk i kystfiske
(Rapport fra Havforskningen;Nr. 5-2013, Working paper, 2013-01)I mai 2012 startet et prosjekt for å undersøke fangstegenskapene til Lofotteina i områder upåvirket av oppdrettsanlegg. Rapporten her beskriver adferdsforsøk i Varanger og fiskeforsøk på Myre og i Mortsund. Lofotteina ble ... -
Long-term fluctuations in cod and pollack along the Norwegian Skagerrak coast
(Journal article; Peer reviewed, 1998-02-12)We tested whether the long-term fluctuations in abundance of 0-group cod Gadus morhua and pollack Pollachius pollachius sampled from 1919 to 1994 at 38 stations along the Norwegian Skagerrak coast might be related to the ... -
Long-term movement patterns of coastal cod (Gadus morhua)
(ICES CM Documents;2001/L:18, Working paper, 2001)Movement patterns were studied by means of hydroacustic telemetry along the Norwegian Skagerrak coast. Ultrasonic transmitters was surgically implanted in 10 coastal cod, and released in the same area as they where caught. ...
