    • Area protection may reduce salmon louse infection risk to wild salmonids 

      Bjørn, Pål Arne; Sivertsgård, Rolf; Finstad, Bengt; Nilsen, Rune; Serra-Llinares, Rosa Maria; Kristoffersen, Roar (Journal article; Tidsskriftartikkel; Peer reviewed, 2011-05-30)
      ABSTRACT: Salmon louse <i>Lepeophtheirus salmonis</i> Krøyer infection levels in both wild sea trout <i>Salmo trutta</i> L. and sentinel Atlantic salmon <i>Salmo salar</i> L. smolts were investigated inside and outside a temporary protected zone with limits on fish farming in the intensively farmed Romsdalsfjord system. Wild sea trout outside the protected zone had higher prevalence and significantly ...

    • Sea trout adapt their migratory behaviour in response to high salmon lice concentrations 

      Halttunen, Elina; Gjelland, Karl Øystein; Hamel, Sandra; Serra-Llinares, Rosa Maria; Nilsen, Rune; Arechavala-Lopez, Pablo; Skardhamar, Jofrid; Asplin, Lars; Karlsen, Ørjan; Bjørn, Pål Arne; Finstad, Bengt (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-21)
      Sea trout face growth–mortality trade-offs when entering the sea to feed. Salmon lice epizootics resulting from aquaculture have shifted these trade-offs, as salmon lice might both increase mortality and reduce growth of sea trout. We studied mortality and behavioural adaptations of wild sea trout in a large-scale experiment with acoustic telemetry in an aquaculture intensive area that was fallowed ...

    • The spread of salmon lice (Lepeophtheirus salmonis Krøyer) from Norwegian fish farms and their impact on sea trout (Salmo trutta L.) 

      Serra-Llinares, Rosa Maria (Doctoral thesis; Doktorgradsavhandling, 2020-10-09)
      <p>The transmission of salmon lice (<i>Lepeophtheirus salmonis</i> Krøyer) from farm salmon to wild salmonids and the impact on wild populations are sources of intense debate in all salmon producing countries, and it is currently an issue of high political and economic relevance in Norway. Solid science-based evidence is therefore needed by decision makers to apply sound management strategies. Given ...
