    • A genetic marker for artificially reared cod (Gadus morhua L.) 

      Jørstad, Knut Eirik; Øiestad, Victor; Paulsen, Ole Ingar; Naas, Kjell Emil; Skaala, Øystein (ICES CM Documents;1987/F:22, Working paper, 1987)
      Artificially reared cod at the Aquaculture Station Austevoll on the west coast of Norway, were screened for genetic markers by using biopsies of white muscle, individual tags and enzyme genotype as determined by starch ...

    • A rare observation of Atlantic halibut larvae (Hippoglossus hippoglossus) in Skjerstadfjorden, North Norway. 

      van der Meeren, Terje; Dahle, Geir; Paulsen, Ole Ingar (Journal article; Peer reviewed, 2013-06-28)
      Four larvae of Atlantic halibut (Hippoglossus hippoglossus) were collected during a larval survey for Atlantic cod (Gadus morhua) in true inshore and shallow locations in the Norwegian fjord system Skjerstadfjorden. This ...

      van der Meeren, Terje; Dahle, Geir; Paulsen, Ole Ingar (Journal article; Peer reviewed, 2013-06-28)
      Four larvae of Atlantic halibut (Hippoglossus hippoglossus) were collected during a larval survey for Atlantic cod (Gadus morhua) in true inshore and shallow locations in the Norwegian fjord system Skjerstadfjorden. This ...

    • Comparative growth and survival of two genetic strains of Atlantic cod (Gadus morhua L.) reared through the early life stages in a marine pond in western Norway 

      Blom, Geir; Svåsand, Terje; Jørstad, Knut Eirik; Otterå, Håkon; Paulsen, Ole Ingar; Holm, Jens Christian (ICES CM Documents;1990/F:48, Working paper, 1990)
      The investigation was carried out in a marine pond in western Norway during spring and summer 1990. Two genetic defined strains of Atlantic cod (Gadus morhua L.) were used as broodstocks. A total of 11.1 x 10^6 cod larvae ...

    • Havbeite med torsk i Hordaland : sluttrapport 

      Otterå, Håkon; Kristiansen, Tore S.; Svåsand, Terje; Borge, Asbjørn; Storaker, Arne; Pedersen, Jan Per; Paulsen, Ole Ingar; Nævdal, Gunnar; Thorkildsen, Solveig (Fisken og havet, Research report, 1997)
      Approximately 250,000 reared, juvenile cod have been released in the Øygarden area, western Norway, during the period 1991 to 1996. An additional 10,000 juveniles have been released at Sotra, and 45,000 at Heimarkspollen, ...

    • Screening for genetic markers to assess potential genetic impact from salmon ranching on wild stocks 

      Skaala, Øystein; Dahle, Geir; Taggart, John B.; Jørstad, Knut Eirik; Unneland, Laila; Karlsen, Tove; Bakke, Gunnar; Paulsen, Ole Ingar (ICES CM Documents;1991/M:14, Working paper, 1991)
      Genetic markers are needed to assess the potential genetic impact on wild salmon populations from ocean ranching. In 1990 spawners from four Norwegian rivers: Lone, Vosso, Dale and Onarheim were screened for genetic ...

    • Silde- og brislingundersøkelser i fjordene, 28.oktober - 10.desember 1989 

      Torstensen, Else; Røttingen, Jostein; Jørstad, Knut Eirik; Paulsen, Ole Ingar (Fisken og havet, Research report, 1999)
      Since 1968 selected fjords from Ryfylke to Finnmark have been surveyed acoustically to obtain an indices of abundance of 0-group sprat and Norwegian Spring Spawning Herring. From 1993 the survey also covers the fjords ...

    • The use of genetic tagging to study interaction between farmed and wild atlantic cod stocks 

      Jørstad, Knut Eirik; van der Meeren, Terje; Dahle, Geir; Paulsen, Ole Ingar; Svåsand, Terje; Otterå, Håkon (ICES CM documents;2009/Q:12, Working paper, 2009)
      Escapement of farmed fish from the aquaculture is considered as a risk for negative genetic impacts on native gene pools. In order to investigate potential interbreeding between cultured and wild Atlantic cod, Gadus ...

    • Wrasse (Labridae) as cleaner fish in salmonid aquaculture – The Hardangerfjord as a case study 

      Skiftesvik, Anne Berit; Blom, Geir; Agnalt, Ann-Lisbeth; Durif, Caroline M.F.; Browman, Howard I.; Bjelland, Reidun M.; Harkestad, Lisbeth S.; Farestveit, Eva; Paulsen, Ole Ingar; Fauske, Merete; Havelin, Trond; Johnsen, Knut; Mortensen, Stein (Journal article; Peer reviewed, 2013-10-15)
      Several species of wrasse (Labridae) are used as cleaner fish to remove salmon lice from farmed Atlantic salmon. We estimated the fishery and use of wrasse in Hardangerfjord. The estimated numbers of labrids used on salmon ...
