    • Can variation in standard metabolic rate explain context- dependent performance of farmed Atlantic salmon offspring? 

      Robertsen, Grethe; Reid, Donald; Einum, Sigurd; Aronsen, Tonje; Fleming, Ian A.; Sundt-Hansen, Line Elisabeth Breivik; Karlsson, Sten; Kvingedal, Eli; Ugedal, Ola; Hindar, Kjetil (Journal article; Peer reviewed, 2018)
      Escaped farmed Atlantic salmon interbreed with wild Atlantic salmon, leaving off- spring that often have lower success in nature than pure wild salmon. On top of this, presence of farmed salmon descendants can impair ...

    • Dynamics of genetic polymorphisms 

      Karlsson, Sten (Doktoravhandlinger ved NTNU, 1503-8181; 2005:17, Doctoral thesis, 2005)

    • Estimering av effektivt antall gytefisk fra stikkprøver av ungfisk av laks - Betydning av antall genetiske markører, antall prøver og romlig fordeling 

      Wacker, Sebastian; Aronsen, Tonje; Hagen, Ingerid Julie; Karlsson, Sten; Berntsen, Henrik Hårdensson; Skoglund, Helge; Solem, Øyvind; Sægrov, Harald; Ugedal, Ola (HydroCen Rapport;28, Research report, 2022)
      Utviklingen innenfor genetiske verktøy gir nye muligheter innen miljøovervåkning. Formålet med undersøkelsene i denne rapporten er å vurdere hvordan ulike faktorer kan påvirke estimater av effektiv be-standsstørrelse. ...

    • Large-effect loci mediate rapid adaptation of salmon body size after river regulation 

      Jensen, Arne Johan; Hagen, Ingerid Julie; Czorlich, Yann; Bolstad, Geir Hysing; Bremset, Gunnbjørn; Finstad, Bengt; Hindar, Kjetil; Skaala, Øystein; Karlsson, Sten (Peer reviewed; Journal article, 2022)
      Understanding the potential of natural populations to adapt to altered environments is becoming increasingly relevant in evolutionary research. Currently, our understanding of adaptation to human alteration of the environment ...

    • Migration and habitat use of the landlocked riverine Atlantic salmon Salmo salar småblank 

      Davidsen, Jan Grimsrud; Eikås, Linda; Hedger, Richard David; Thorstad, Eva Bonsak; Rønning, Lars; Sjursen, Aslak Darre; Berg, Ole Kristian; Bremset, Gunnbjørn; Karlsson, Sten; Sundt-Hansen, Line Elisabeth Breivik (Peer reviewed; Journal article, 2020)
      “Småblank” is the only population of Atlantic salmon in Europe living its entire life in the river habitat without performing migrations to the sea or lakes. Home range size and habitat use were compared between an unregulated ...

    • Spatial and temporal genetic structure of a river-resident Atlantic salmon (Salmo salar) after millennia of isolation 

      Sandlund, Odd Terje; Karlsson, Sten; Thorstad, Eva Bonsak; Berg, Ole Kristian; Kent, Matthew Peter; Norum, Ine Cecilie Jordalen; Hindar, Kjetil (Journal article; Peer reviewed, 2014)
      The river-resident Salmo salar (“småblank”) has been isolated from other Atlantic salmon populations for 9,500 years in upper River Namsen, Norway. This is the only European Atlantic salmon population accomplishing its ...

    • Survival and growth of farmed, hybrid, and wild salmon during migration in the North Atlantic Ocean 

      Chatterjee, Gunjari (Master thesis, 2023)
      Aquaculture has become a significant source of food, surpassing wild fisheries, and contributes to global food security, economic growth, and poverty alleviation. Among various teleost species, Atlantic salmon (Salmo salar ...

    • Vandringer og habitatbruk til småblank 

      Davidsen, Jan Grimsrud; Eikås, Linda; Hedger, Richard David; Rønning, Lars; Sjursen, Aslak Darre; Thorstad, Eva Bonsak; Berg, Ole Kristian; Bremset, Gunnbjørn; Karlsson, Sten; Sundt-Hansen, Line Elisabeth Breivik (NTNU Vitenskapsmuseet naturhistorisk rapport;, Research report, 2018)
      Småblank er den eneste rent elvelevende laksen i Europa, og finnes kun i øvre deler av Nam-senvassdraget. Størrelsen på bestanden er ukjent, men det er grunn til at tro at bestandstettheten har gått ned siden 1950- tallet, ...

    • Wild salmonids are running the gauntlet of pathogens and climate as fish farms expand northwards 

      Vollset, Knut; Lennox, Robert J.; Davidsen, Jan Grimsrud; Eldøy, Sindre Håvarstein; Isaksen, Trond Einar; Madhun, Abdullah Sami; Karlsson, Sten; Miller, Kristina M (Peer reviewed; Journal article, 2020)
      Salmon farming has multiplied from a side business of coastal farmers to one of the world's major aquaculture species. This has dramatically altered the disease dynamics between farmed and wild salmonids. As salmon fish ...
