    • Acoustic accelerometer transmitters and their growing relevance to aquatic science 

      Lennox, Robert; Eldøy, Sindre Håvarstein; Dahlmo, Lotte Svengård; Matley, Jordan K.; Vollset, Knut (Peer reviewed; Journal article, 2023)
      There has recently been great interest in the use of accelerometers onboard electronic transmitters to characterise various aspects of the ecology of wild animals. We review use cases and outline how these tools can provide ...

    • Development of a risk assessment for sea trout in coastal areas exploited for aquaculture 

      Finstad, Bengt; Sandvik, Anne Dagrun; Ugedal, Ola; Vollset, Knut; Karlsen, Ørjan; Davidsen, Jan Grimsrud; Sægrov, Harald; Lennox, Robert J. (Peer reviewed; Journal article, 2021)
      ABSTRACT: The regulation of aquaculture production in Norway considers the potential impact of salmon lice on wild fish. However, most attention has been focused on impacts on wild Atlantic salmon, despite the fact that ...

    • How pathogens affect the marine habitat use and migration of sea trout (Salmo trutta) in two Norwegian fjord systems 

      Lennox, Robert J.; Eldøy, Sindre Håvarstein; Vollset, Knut; Miller, Kristi M.; Li, Shaorong; Kaukinen, Karia H.; Isaksen, Trond Einar; Davidsen, Jan Grimsrud (Peer reviewed; Journal article, 2020)
      Wild fish are confronting changing pathogen dynamics arising from anthropogenic disturbance and climate change. Pathogens can influence animal behaviour and life histories, yet there are little such data from fish in the ...

    • 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 ...

    • Predation of Atlantic salmon across ontogenetic stages and impacts on populations 

      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 ...

    • 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 ...
