    • Incidence and impacts of escaped farmed Atlantic salmon Salmo salar in nature 

      Thorstad, Eva B.; Fleming, Ian A.; McGinnity, Philip; Soto, Doris; Wennevik, Vidar; Whoriskey, Fred (NINA Special Report;36, Book, 2008)
      Since the mid-1960s, Atlantic salmon Salmo salar farming has grown into a large industry within and beyond the native range of the species. Norway, Chile, Scotland and Canada are the largest producers (46, 31, 10 and 7% ...

      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. ...

    • Novel large-scale mapping highlights poor state of sea trout populations 

      Fiske, Peder; Forseth, Torbjørn; Thorstad, Eva Bonsak; Bakkestuen, Vegar; Einum, Sigurd; Falkegård, Morten; Garmo, Øyvind A.; Garseth, Åse Helen; Skoglund, Helge; Solberg, Monica Favnebøe; Utne, Kjell Rong; Vollset, Knut; Vøllestad, Leif Asbjørn; Wennevik, Vidar (Peer reviewed; Journal article, 2024)
      1. The state of sea trout in 1251 Norwegian watercourses was assessed based on a scoring system for human pressures, abundance data, and local knowledge. 2. Over 16,000 km of rivers and lakes were available to sea trout ...

      Falkegård, Morten; Lennox, Robert; Thorstad, Eva Bonsak; Einum, Sigurd; Fiske, Peder; Garmo, Øyvind Aaberg; Garseth, Åse Helen; Skoglund, Helge; Solberg, Monica Favnebøe; Utne, Kjell Rong; Vollset, Knut; Vøllestad, Leif Asbjørn; Wennevik, Vidar; Forseth, Torbjørn (Peer reviewed; Journal article, 2023)
      Managers and stakeholders increasingly ask whether predation is a driving force behind the poor status of many species, and whether predator control is likely to be a successful management action to intervene. We review ...

    • Status for norske laksebestander i 2023
