      Determining the mechanisms driving range-wide reductions in Atlantic salmon marine survival is hindered by an insufcient understanding of their oceanic ecology and distribution. We attached 204 pop-up satellite archival ...
    • Repeatable individual variation in migration timing in two anadromous salmonids and ecological consequences 

      Jensen, Arne Johan; Finstad, Bengt; Fiske, Peder; Diserud, Ola Håvard; Thorstad, Eva Bonsak (Journal article; Peer reviewed, 2020)
      Consistent individual differences in behavior have been demonstrated for many animals, but there are few studies of consequences of such repeated behavior in the wild. We tested consistency in migration timing to and from ...
    • Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
