    • Optimal estimation of lice release from aquaculture based on ambient temperatures 

      Johnsen, Ingrid A.; Stien, Lars Helge; Sandvik, Anne Dagrun; Asplin, Lars; Oppedal, Frode (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-30)
      Models for mapping and forecasting infective pressure from salmon louse <i>Lepeophtheirus salmonis</i> larvae are of major importance in the Norwegian government’s management of salmonid aquaculture. These models use site-reported temperature and number of egg-producing female adult lice present within cages to calculate how many lice eggs and larvae are released from individual farms. The reported ...

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

      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 ...
