    • An effective method for the recapture of escaped farmed salmon 

      Chittenden, Cedar; Rikardsen, Audun H.; Skilbrei, Ove Tommy; Davidsen, Jan Grimsrud; Halttunen, Elina; Skardhamar, Jofrid; McKinley, R. Scott (Journal article; Peer reviewed, 2011)
      The search for effective strategies to prevent and mitigate accidental releases of aquaculture fishes is on-going. To test a new recapture strategy and evaluate the individual dispersal behaviour of escaped farmed Atlantic ...

    • Efectos del piojo del salmón Lepeophtheirus salmonis(Copepoda: Caligidae) en las poblaciones de truchas (Salmo trutta) de la costa NE Atlántica 

      Lopez, Pablo Arachavala; Thorstad, Eva Bonsak; Todd, Christopher D.; Uglem, Ingebrigt; Bjørn, Pål Arne; Gargan, Patrick G.; Vollset, Knut Wiik; Halttunen, Elina; Kålås, Steinar; Berg, Marius; Finstad, Bengt (Peer reviewed; Journal article, 2015)
      Salmon lice are external parasites on salmonids in the marine environment. During recent years, sea lice abundance has been increased due to the presence of salmon farming using on-growing floating seas-cages. Amongst ...

    • Effects of salmon lice Lepeophtheirus salmonis onwild sea trout Salmo trutta—a literature review 

      Thorstad, Eva Bonsak; Todd, Christopher D.; Uglem, Ingebrigt; Bjørn, Pål Arne; Gargan, Patrick G.; Vollset, Knut Wiik; Halttunen, Elina; Kålås, Steinar; Berg, Marius; Finstad, Bengt (Journal article; Peer reviewed, 2015-08-20)
      Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, ...

    • Migration of Atlantic salmon post-smolts in a fjord with high infestation pressure of salmon lice 

      Halttunen, Elina; Gjelland, Karl Øystein; Glover, Kevin; Johnsen, Ingrid Askeland; Serra-Llinares, Rosa-Maria; Skaala, Øystein; Nilsen, Rune; Bjørn, Pål Arne; Karlsen, Ørjan; Finstad, Bengt; Skilbrei, Ove Tommy (Peer reviewed; Journal article, 2018)
      Understanding Atlantic salmon Salmo salar post-smolt coastal migration behaviour is crucial for predicting their exposure to ecological challenges such as the parasite salmon louse Lepeophtheirus salmonis. We compared the ...

    • Modelled salmon lice dispersion and infestation patterns in a sub-arctic fjord 

      Skardhamar, Jofrid; Albretsen, Jon; Sandvik, Anne Dagrun; Lien, Vidar Surén; Myksvoll, Mari Skuggedal; Johnsen, Ingrid Askeland; Asplin, Lars; Ådlandsvik, Bjørn; Halttunen, Elina; Bjørn, Pål Arne (Journal article; Peer reviewed, 2018)
      Salmon lice infestation is a major challenge for the aquaculture industry in Norway, threatening wild salmonid populations and causing welfare problems for farmed salmon. Lice dispersion and infestation patterns are simulated ...

    • 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; Johnsen, Ingrid Askeland; Asplin, Lars; Karlsen, Ørjan; Bjørn, Pål Arne; Finstad, Bengt (Peer reviewed; Journal article, 2017)
      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 ...
