    • Area use and movement patterns of wild and escaped farmed Atlantic salmon before and during spawning in a large Norwegian river 

      Moe, Karina; Næsje, Tor; Haugen, Thrond Oddvar; Ulvan, Eva Marita; Aronsen, Tonje; Sandnes, Tomas; Thorstad, Eva Bonsak (Journal article, 2016)
      We compared the within-river movements and distribution of wild and escaped farmed Atlantic salmon Salmo salar before and during spawning in the Namsen river system of Central Norway. A total of 74 wild and 43 escaped ...

    • Escape history and proportion of farmed Atlantic salmon Salmo salar on the coast and in an adjacent salmon fjord in Norway 

      Aronsen, Tonje; Ulvan, Eva Marita; Næsje, Tor; Fiske, Peder (Peer reviewed; Journal article, 2020)
      To gain more knowledge about escaped farmed salmon Salmo salar in the wild, we investigated the proportion of escapees, body length at escape, proportion escaped as smolts/post-smolts (≤300 mm) and number of winters in the ...

    • Escaped farmed Atlantic salmon in Norwegian rivers during 1989–2013 

      Diserud, Ola Håvard; Fiske, Peder; Sægrov, Harald; Urdal, K.; Aronsen, Tonje; Lo, Håvard; Barlaup, Bjørn Torgeir; Niemela, Eero; Orell, P.; Erkinaro, J.; Lund, Roar A.; Økland, Finn; Østborg, Gunnel Marie; Hansen, Lars Petter; Hindar, Kjetil (Journal article; Peer reviewed, 2019)
      We report on the data from an extensive monitoring programme for the occurrence of escaped farmed Atlantic salmon (Salmo salar) in Norwegian rivers for 25 years. This monitoring started as a 3-year research programme in ...

    • Natural and anthropogenic drivers of escaped farmed salmon occurrence and introgression into wild Norwegian Atlantic salmon populations 

      Diserud, Ola Håvard; Fiske, Peder; Karlsson, Sten; Glover, Kevin Alan; Næsje, Tor; Aronsen, Tonje; Bakke, Gunnar O; Barlaup, Bjørn Torgeir; Erkinaro, J.; Florø-Larsen, Bjørn; Foldvik, Anders; Heino, Mikko Petteri; Kanstad-Hanssen, Øyvind; Lo, Håvard; Lund, Roar Asbjørn; Muladal, R.; Niemela, E.; Økland, Finn; Østborg, Gunnel Marie; Otterå, Håkon Magne; Skaala, Øystein; Skoglund, Helge; Solberg, Ingrid; Solberg, Monica Favnebøe; Sollien, Vegard Pedersen; Sægrov, Harald; Urdal, Kurt; Wennevik, Vidar; Hindar, Kjetil (Peer reviewed; Journal article, 2022)
      Marine aquaculture of Atlantic salmon (Salmo salar) is a relatively new industry where breeding programs have led to rapid genetic change in the captive populations that were built up alongside conspecific wild individuals. ...

    • Selection against individuals from genetic introgression of escaped farmed salmon in a natural population of Atlantic salmon 

      Wacker, Sebastian; Aronsen, Tonje; Karlsson, Sten; Ugedal, Ola; Diserud, Ola Håvard; Ulvan, Eva Marita; Hindar, Kjetil; Næsje, Tor (Peer reviewed; Journal article, 2021)
      The viability of wild Atlantic salmon populations is threatened by genetic introgression from escaped farmed salmon. Farmed Atlantic salmon are genetically improved for important commercial traits and a life in captivity ...

    • Sex in murky waters: algal-induced turbidity increases sexual selection in pipefish 

      Sundin, Josefin; Aronsen, Tonje; Rosenqvist, Gunilla; Berglund, Anders (Journal article; Peer reviewed, 2017)
      Algal-induced turbidity has been shown to alter several important aspects of reproduction and sexual selection. However, while turbidity has been shown to negatively affect reproduction and sexually selected traits in ...
