    • Effects of salmon lice infection on the behaviour of sea trout in the marine phase 

      Gjelland, Karl Øystein; Serra-Llinares, Rosa Maria; Hedger, Richard David; Arechavala-Lopez, Pablo; Nilsen, Rune; Finstad, Bengt; Uglem, Ingebrigt; Skilbrei, Ove Tommy; Bjørn, Pål Arne (Peer reviewed, 2014)
      Salmon lice Lepeophtheirus salmonis Krøyer may affect survival and growth of anadromous salmonids through physiological stress and/or behavioural changes. Using acoustic telemetry tracking, we investigated the behaviour ...

    • Optimal size at seaward migration in an anadromous salmonid 

      Jonsson, Bror; Jonsson, Marius; Jonsson, Nina (Journal article; Peer reviewed, 2016)
      In this study, the probabilistic reaction norm was calculated for length at different ages of smolting before seaward migration of Atlantic salmon Salmo salar spawning in the Norwegian River Imsa. The reaction norm was ...

    • Salmon louse infestation in wild brown trout populations generates multi-modal mixture distributions 

      Diserud, Ola Håvard; Hedger, Richard David; Finstad, Bengt; Hendrichsen, Ditte Katrine; Jensen, Arne Johan; Ugedal, Ola (Peer reviewed; Journal article, 2020)
      For successful evaluation of the overall effects of salmon louse infestation on brown trout population dynamics, it is crucial to have a realistic understanding of how lice infestation distributions are generated and how ...
