    • Behaviour and habitat use of first-time migrant Arctic charr: novel insights from a subarctic marine area 

      Nordli, Eivind; Strøm, John Fredrik; Bøhn, Thomas; Thorstad, Eva Bonsak; Serra Llinares, Rosa Maria; Nilsen, Rune; Bjørn, Pål Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-13)
      Anadromous Arctic charr Salvelinus alpinus is a cold-adapted salmonid that is vulnerable to climate warming and anthropogenic activities including salmon farming, hydropower regulation, and pollution, which poses a multiple-stressor scenario that influences or threatens populations. We studied the horizontal and vertical behaviour of Arctic charr tagged with acoustic transmitters (n = 45, mean ...

    • The behaviour of anadromous Arctic charr during their first marine migration 

      Nordli, Eivind (Master thesis; Mastergradsoppgave, 2021-05-17)
      Climate change-induced alterations of aquatic ecosystems, increased water temperature and human activity are substantial stressors to anadromous Arctic charr, and these are all expected to increase in the future. The knowledge of the marine behaviour of anadromous Arctic charr, especially post-smolts, is limited and few studies has described their residency at sea in detail. Therefore, more ...

    • Sea trout Salmo trutta in the subarctic: home-bound but large variation in migratory behaviour between and within populations 

      Strøm, John Fredrik; Jensen, Jenny L. A.; Nikolopoulos, Anna; Nordli, Eivind; Bjørn, Pål Arne; Bøhn, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-28)
      Anadromous brown trout (sea trout), Salmo trutta, is currently in decline throughout its range, largely due to anthropogenic stressors in freshwater and marine habitats. Acoustic telmetry was utilized to study the marine migration of sea trout post-smolts from three populations in a relatively pristine subarctic fjord system. While at sea, the sea trout spent a substantial part of their time close ...
