Spatial and temporal overlap and trophic interactions between Atlantic Saithe (Pollachius virens) and Norwegian spring spawning herring (Clupea harengus) on herring spawning grounds
Slotte, Aril; Runde, Arne; Skaret, Georg; Axelsen, Bjørn Erik; Fernö, Anders; Johannessen, Arne; Nøttestad, Leif; Øvredal, Jan Tore (ICES CM documents, Working paper, 2005)Atlantic saithe (Pollachius virens) and Norwegian spring-spawning herring (Clupea harengus) represent two of the most abundant and ecologically important fish species in the Northeast Atlantic. The two species co-occur ... -

Surface activity of Atlantic salmon (Salmo salar) in net pens
Furevik, Dag M.; Huse, Ingvar; Bjordal, Åsmund; Fernö, Anders (ICES CM Documents;1988/F:19, Working paper, 1988)An important feature of the behaviour of salmon is the leaping and rolling activity. These surface activities were studied in fish in net pens in relation to environmental factors and operational procedures. Data were ... -
The challenge of the herring in the Norwegian Sea: making optimal collective spatial decision
Fernö, Anders; Melle, Webjørn; Misund, Ole Arve; Pitcher, Tony; Nøttestad, Leif; Mackinson, Steven; Hollingworth, Charles (ICES CM Documents;1996/H:15, Working paper, 1996)Herring are long-lived multiple spawners exhibiting strong variation in reproductive and recruitment success between years. They tend to adopt low-risk, preferred-conservative strategies; for example, shifts to alternative ... -
The effect of shading in pen rearing of Atlantic salmon (Salmo salar)
Huse, Ingvar; Bjordal, Åsmund; Fernö, Anders; Furevik, Dag M. (ICES CM Documents;1988/F:18, Working paper, 1988)A full scale pen rearing experiment with covers to reduce illumination was carried out. No significant effects were observed on growth, mortality, ectoparasite infection, maturation or net pen fouling.
