    • Ocean migration of pop-up satellite archival tagged Atlantic salmon from the Miramichi River in Canada 

      Strøm, John Fredrik; Thorstad, Eva Bonsak; Chafe, Graham; Sørbye, Sigrunn Holbek; Righton, David; Rikardsen, Audun H.; Carr, Jonathan (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-13)
      The ocean migration of 16 post-spawned adult Atlantic salmon [Salmo salar L.] from the Miramichi River, Canada, tagged concurrently with pop-up satellite archival tags and acoustic transmitters was reconstructed using a Hidden Markov Model. Individuals exclusively utilized areas within the Gulf of St Lawrence and the Labrador Sea, and showed little overlap with known distributions of European stocks. ...

    • Ocean predation and mortality of adult Atlantic salmon 

      Strøm, John Fredrik; Rikardsen, Audun H.; Campana, Steven E.; Righton, David; Carr, Jonathan; Aarestrup, Kim; Stokesbury, Michael J.W.; Gargan, Patrick G.; Caballero Javierre, Pablo; Thorstad, Eva Bonsak (Journal article; Peer reviewed, 2019-05-27)
      Predation and mortality are often difficult to estimate in the ocean, which hampers the management and conservation of marine fishes. <br>We used data from pop-up satellite archival tags to investigate the ocean predation and mortality of adult Atlantic salmon (Salmo salar) released from 12 rivers flowing into the North Atlantic Ocean. Data from 156 tagged fish revealed 22 definite predation ...

We used data from pop-up satellite archival tags to investigate the ocean predation and mortality of adult Atlantic salmon (Salmo salar) released from 12 rivers flowing into the North Atlantic Ocean.

    • Redefining the oceanic distribution of Atlantic salmon 

      Rikardsen, Audun H.; Righton, David; Strøm, John Fredrik; Thorstad, Eva Bonsak; Gargan, Patrick G.; Sheehan, Timothy F.; Økland, Finn; Chittenden, Cedar; Hedger, Richard David; Næsje, Tor; Renkawitz, Mark; Sturlaugsson, Johannes; Caballero, Pablo; Baktoft, Henrik; Davidsen, Jan Grimsrud; Halttunen, Elina; Wright, Serena; Finstad, Bengt; Aarestrup, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-10)
      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 tags to post-spawned salmon when they migrated to the ocean from seven European areas and maiden North American salmon captured at sea at West Greenland. Individuals migrated ...
