    • Present status of an intensive cod-rearing experiment at Austevoll, Norway 

      Huse, Ingvar; Lohne Gokstad, Svanhild; Grav, Torfinn; Jensen, Per Anders; Kristiansen, Arve; Opstad, Ingegjerd (ICES CM Documents;1982/F:16, Working paper, 1982)

    • Production experiment of halibut fry (Hippoglossus hippoglossus) in silos 

      Rabben, Håvard; Jelmert, Anders; Huse, Ingvar (ICES CM Documents;1987/F:42, Working paper, 1987)
      Silos with conical bottoms and a volume of approx 3.5 m3 are tested as storing units for halibut yolk-sac larvae. The silos were run in three different ways: A: Stagnant water with a saltplug till day 10 and later slow ...

    • Production experiment of halibut fry in large enclosed water columns 

      Rabben, Håvard; Nilsen, T.O.; Huse, Ingvar; Jelmert, Anders (ICES CM Documents;1986/F:19, Working paper, 1986)
      Halibut eggs were hatched in 21 floating enclosures and the larvae stored through the yolk sac period under 5 different environmental conditions, each with 4 parallels. The effect of the different environments was ...

    • Qualitative and quantitative behaviour studies in starving and feeding turbot (Scopthalmus maximus L.) larvae 

      Huse, Ingvar; Skiftesvik, Anne Berit (ICES CM Documents;1985/F:38, Working paper, 1985)
      A computer aided video system was used to register three dimensional movement and behaviour patterns in starving and feeding turbot larvae. The feeding larvae were kept and were monitored beyond metamorphosis in the ...

    • Qualitative contrast comparisons of differently coloured gillnets. 

      Angelsen, Karl Kr.; Huse, Ingvar (ICES CM Documents;1979/B:20, Working paper, 1979)
      A regularly returning problem for Norwegian gill net manufacturers has been that fishermen often change their fancy for gill net colours, and also that fishermen from different districts have separate colour preferences. ...

    • Status of an intensive cod rearing project in Norway. 

      Huse, Ingvar; Jensen, Per Anders (ICES CM Documents;1980/F:23, Working paper, 1980)
      Cod yolk sac larvae were start fed with natural plancton in plastic pens. Eggs were obtained from a plastic spawning pen where cod spawned naturally. An attempt to incubate eggs directly in the start feed pens failed. ...

    • 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 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.

    • Variation in acoustically measured abundance from repeated surveys of herring 

      Huse, Ingvar; Ostrowski, Marek (ICES CM documents, Working paper, 1998)
      A large concentration of wintering herring was surveys continuously with acoustics over 37 hours in a fjord in Northern Norway. 16 surveys of the same area were conducted. Total abundance and statistics were computed for ...

    • Vertical distribution of cod, haddock and redfish; Impact on bottom trawl and acoustic surveys in the Barents Sea 

      Aglen, Asgeir; Engås, Arill; Huse, Ingvar; Michalsen, Kathrine; Stensholt, Boonchai K. (ICES CM Documents;1997/Y:16, Working paper, 1997)
      At a selected location in the Barents Sea acoustic observations, bottom- and pelagic trawl catch data were collected over a 10 day period. A large proportion of the fish were in the acoustic dead zone during the sampling ...
