    • Effects of salmon lice (Lepeophtheirus salmonis) on wild caught sea trout (Salmo trutta) under experimental conditions 

      Ambjørndalen, Vegard Masteholtet (Master thesis, 2017)
      An increasing net cage farming of salmonids in Norway are leading to increased production of infective salmon louse (Lepeophtheirus salmonis) larvae in coastal areas. One of the most vulnerable salmonids for salmon lice ...
    • Environmental influences on life history strategies in partially anadromous brown trout (Salmo trutta, Salmonidae) 

      Nevoux, Marie; Finstad, Bengt; Davidsen, Jan Grimsrud; Finlay, Ross; Josset, Quentin; Poole, Rusell; Höjesjö, Johan; Aarestrup, Kim; Persson, Lo; Tolvanen, Oula; Jonsson, Bror (Journal article; Peer reviewed, 2019)
      This paper reviews the life history of brown trout and factors influencing decisions to migrate. Decisions that maximize fitness appear dependent on size at age. In partly anadromous populations, individuals that attain ...
    • Fiskebiologiske undersøkelser i Auravassdraget. Årsrapport 2005 

      Jensen, Arne Johan; Finstad, Bengt; Hvidsten, Nils Arne; Jensås, Jan Gunnar; Johnsen, Bjørn Ove; Lund, Egil; Kjøsnes, Arne; Solem, Øyvind (NINA rapport;115, Research report, 2006)
      Formålet med denne undersøkelsen er å overvåke utviklingen av bestandene av laks og sjøør-ret i Auravassdraget. Resultatene skal danne grunnlag for å evaluere de tiltakene som er gjen-nomført som kompensasjon for negative ...
    • Heart rate and swimming activity as stress indicators for Atlantic salmon (Salmo salar) 

      Svendsen, Eirik; Føre, Martin; Økland, Finn; Gräns, Albin; Hedger, Richard David; Alfredsen, Jo Arve; Uglem, Ingebrigt; Rosten, Carolyn; Frank, Kevin; Erikson, Ulf Gøran; Finstad, Bengt (Peer reviewed; Journal article, 2020)
      We investigated the relationship between telemetry measurements of heart rate and swimming activity and the physiological status in farmed Atlantic salmon (Salmo salar) to assess the potential to use telemetry measurements ...
    • Impacts of parasites on marine survival of Atlantic salmon: a meta-analysis 

      Vollset, Knut Wiik; Krontveit, Randi Ingebjørg; Jansen, Peder A; Finstad, Bengt; Barlaup, Bjørn Torgeir; Skilbrei, Ove Tommy; Krkošek, Martin; Romundstad, Pål Richard; Aunsmo, Arnfinn; Jensen, Arne Johan; Dohoo, Ian (Journal article; Peer reviewed, 2016)
      Parasites can, in theory, have large impacts on the survival of fish populations. One method to evaluate such impacts on anadromous species is to apply manipulative field experiments in which parallel groups of antiparasitically ...
    • Innsamling og sammenstilling av relevant kunnskap om Sognefjorden

    • Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance 

      Fjørtoft, Helene Børretzen; Nilsen, Frank; Besnier, Francois; Stene, Anne; Bjørn, Pål Arne; Tveten, Ann-Kristin; Aspehaug, Vidar Teis; Finstad, Bengt; Glover, Kevin (Journal article; Peer reviewed, 2019)
      Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ...
    • The operationalisation of sustainability: Sustainable aquaculture production as defined by certification schemes 

      Osmundsen, Tonje Cecilie; Amundsen, Vilde Steiro; Alexander, Karen A.; Asche, Frank; Bailey, Jennifer Leigh; Finstad, Bengt; Olsen, Marit Schei; Hernandez, Klaudia; Salgado, Hugo (Journal article; Peer reviewed, 2020)
      Sustainability certification has become an increasingly important feature in aquaculture production, leading to a multitude of schemes with various criteria. However, the large number of schemes and the complexity of the ...
    • The Phe362Tyr mutation conveying resistance to organophosphates occurs in high frequencies in salmon lice collected from wild salmon and trout 

      Fjørtoft, Helene Børretzen; Besnier, Francois; Stene, Anne; Nilsen, Frank; Bjørn, Pål Arne; Tveten, Ann-Kristin; Finstad, Bengt; Aspehaug, Vidar; Glover, Kevin (Journal article; Peer reviewed, 2017)
      The parasitic salmon louse, and its resistance to chemical delousing agents, represents one of the largest challenges to the salmon aquaculture industry. We genotyped lice sampled from wild salmon and sea trout throughout ...
    • Timing is everything: Survival of Atlantic salmon Salmo salar postsmolts during events of high salmon lice densities 

      Bøhn, Thomas; Gjelland, Karl Øystein; Serra Llinares, Rosa Maria; Finstad, Bengt; Primicerio, Raul; Nilsen, Rune; Karlsen, Ørjan; Sandvik, Anne Dagrun; Skilbrei, Ove Tommy; Elvik, Kristine Marit Schrøder; Skaala, Øystein; Bjørn, Pål Arne (Peer reviewed; Journal article, 2020)
      Atlantic salmon in aquaculture act as reservoir hosts and vectors of parasites like salmon lice and this parasite is shown to harm wild salmonid populations. In this study, n = 29,817 tagged Atlantic salmon were studied ...
