    • Keeping close to the river, shore and surface: the first marine migration of brown trout (Salmo trutta) and Arctic charr (Salvelinus alpinus) post-smolts 

      Atencio, Benjamin J.; Thorstad, Eva Bonsak; Rikardsen, Audun H.; Jensen, Jenny Lovisa Alexandra (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-23)
      Acoustic telemetry was utilized to track 49 brown trout (<i>Salmo trutta</i>) and 37 Arctic charr (<i>Salvelinus alpinus</i>) first-time migrants of wild origin [post-smolts; mean LF (fork length): 169 and 172 mm] in a large fjord in northern Norway. The <i>S. trutta</i> were registered at sea for more than twice the time of the <i>S. alpinus</i> (medians of 54 and 22 days, respectively). Both species ...

    • Micro- and macro-habitat selection of Atlantic salmon, (Salmo salar), post-smolts in relation to marine environmental cues 

      Jensen, Jenny Lovisa Alexandra; Strøm, John Fredrik; Nikolopoulos, Anna; Primicerio, Raul; Skardhamar, Jofrid; Atencio, Benjamin J.; Strand, Jo Espen Tau; Bjørn, Pål Arne; Bøhn, Thomas (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-20)
      Atlantic salmon is an economically and culturally important species. The species encounters several natural and man-made threats during its migration between fresh water and the ocean, which in combination may explain its ongoing decline. With the aim to better understand whether post-smolt behaviour is influenced by physical oceanographic conditions, the migratory behaviour of 173 post-smolts in a ...

    • Recent Salmon Declines : A Result of Lost Feeding Opportunities Due to Bad Timing? 

      Ewart, David; Chittenden, Cedar Marget; Jensen, Jenny Lovisa Alexandra; Anderson, Shannon; Balfry, Shannon; Downey, Elan; Eaves, Alexandra; Saksida, Sonja; Smith, Brian; Vincent, Stephen; Welch, David; McKinley, Scott (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)

    • The seasonal migratory behavior of sympatric anadromous Arctic charr and brown trout 

      Jensen, Jenny Lovisa Alexandra (Doctoral thesis; Doktorgradsavhandling, 2013-09-20)
      This thesis used acoustic and archival telemetry to study fish migrations within and between freshwater and marine habitats. The main novel finding from this thesis work is that both Arctic charr and brown trout originating from rivers without access to lakes can be found in marine waters also during winter. The physical properties of the freshwater habitat may be the main factor controlling in which ...

    • Winter behaviour of riverine anadromous Arctic charr and sea trout in northern Norway 

      Jensen, Jenny Lovisa Alexandra (Master thesis; Mastergradsoppgave, 2008-05)
      Based on earlier migration studies of lake-dwelling anadromous Arctic charr Salvelinus alpinus (L.) and sea trout Salmo trutta L. in northern Norway, both species are believed to solely overwinter in fresh water and spend only one to three months in the sea during summer. This is an assumption upon which all current management of the species in the area is based, although no studies have focused on ...
