    • Caught in the trap: over half of the farmed Atlantic salmon removed from a wild spawning population in the period 2014−2018 were mature 

      Madhun, Abdullah Sami; Harvey, Alison C.; Skaala, Øystein; Wennevik, Vidar; Knutar, Sofie; Solberg, Monica Favnebøe; Quintela, Maria; Andersen-Fjeldheim, Per Tommy; Meier, Sonnich; Glover, Kevin Alan (Peer reviewed; Journal article, 2023)
      Whilst aquaculture continues its global expansion, containment of fish in sea cages remains a persistent environmental challenge. Within Atlantic salmon Salmo salar farming, widespread escapes over several decades have ...

    • DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity 

      Kaland, Håvard; Harvey, Alison C.; Skaala, Øystein; Wennevik, Vidar; Besnier, Francois; Andersen-Fjeldheim, Per Tommy; Knutar, Sofie; Andersen-Fjeldheim, Kaja Christine; Glover, Kevin Alan (Peer reviewed; Journal article, 2023)
      Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult ...

    • Inferring Atlantic salmon post-smolt migration patterns using genetic assignment 

      Harvey, Alison C.; Sanchez, Maria Quintela; Glover, Kevin; Karlsen, Ørjan; Nilsen, Rune; Skaala, Øystein; Sægrov, Harald; Kolås, Steinar; Knutar, Sofie; Wennevik, Vidar (Journal article; Peer reviewed, 2019)
      Understanding migratory patterns is important for predicting and mitigating unwanted consequences of environmental change or anthropogenic challenges on vulnerable species. Wild Atlantic salmon undergo challenging migrations ...

    • Introgression of domesticated salmon changes life history and phenology of a wild salmon population 

      Besnier, Francois; Ayllon, Fernando; Skaala, Øystein; Solberg, Monica Favnebøe; Fjeldheim, Per Tommy; Andersen, Kaja Christine; Knutar, Sofie; Glover, Kevin Alan (Peer reviewed; Journal article, 2022)
      The release of domesticated conspecifics into the natural environment, whether deliberate or accidental, has the potential to alter the genetic integrity and evolutionary trajectory of wild populations. This widespread ...

    • Time series covering up to four decades reveals major changes and drivers of marine growth and proportion of repeat spawners in an Atlantic salmon population 

      Harvey, Alison C.; Skaala, Øystein; Borgstrøm, Reidar; Andersen-Fjeldheim, Per Tommy; Andersen-Fjeldheim, Kaja Christine; Utne, Kjell Rong; Johnsen, Ingrid Askeland; Fiske, Peder; Winterthun, Synnøve; Knutar, Sofie; Sægrov, Harald; Urdal, Kurt; Glover, Kevin Alan (Peer reviewed; Journal article, 2022)
      Wild Atlantic salmon populations have declined in many regions and are affected by diverse natural and anthropogenic factors. To facilitate management guidelines, precise knowledge of mechanisms driving population changes ...

    • Wild Atlantic salmon enter aquaculture sea-cages: A case study 

      Fjelldal, Per Gunnar; Bui, Samantha; Hansen, Tom Johnny; Oppedal, Frode; Bakke, Gunnar O; Hellenbrecht, Lea Marie; Knutar, Sofie; Madhun, Abdullah Sami (Peer reviewed; Journal article, 2021)
      There are more than 3,000 Atlantic salmon aquaculture sea-cages distributed along the coastline of Norway. Many of these sea-cages are located along the migration routes of wild Atlantic salmon (Salmo salar) postsmolts. ...
