    • Akustisk mengdemåling av oppdrettslaks 

      Juell, Jon-Erik; Fosseidengen, Jan Erik (Fisken og havet, Research report, 1995)
      Continuous monitoring of the biomass in salmon cages is likely to increase the production efficiency. It would optimize density-dependent farm procedures, e.g food and drug administration, and provide a possibility for ...

    • Biomassekartlegging av Laminaria digitata i Smøla-området 

      Sjøtun, Kjersti; Olsen, Bernt R.; Eggereide, Sarah Fagertun (Fisken og havet, Research report, 2004)
      The biomass density of Laminaria digitata was examined on a total of 28 stations in the Smøla area (the county of Møre og Romsdalen). The highest abundance of L. digitata was found in the outermost and most wave-exposed ...

    • Dyreplankton i Barentshavet biomasse-variasjoner 1979 - 1994 

      Hassel, Arne (Fisken og havet, Research report, 1995)
      The capelin fisheries has until recently been a very important commercial fishery in the Barents Sea. The capelin stock has showed large fluctuations, with a size of about 4-7 mill. tons in 1973-1980 before the collapse ...

    • Sammenheng mellom geometriske dimensjoner og biomasse hos sildestimer under innvandring til overvintringsområdene 

      Nøttestad, Leif (Fisken og havet, Research report, 1996)
      Repeated acoustic measurements of size, density and biomass of herring schools were conducted using sonar and echosounder connected to echointegrator system (Simrad EY-500) in Vestfjorden, Ofotfjorden and Tysfjord in the ...
