Considering sampling bias in close-kin mark–recapture abundance estimates of Atlantic salmon
Wacker, Sebastian; Skaug, Hans Julius; Forseth, Torbjørn; Solem, Øyvind; Ulvan, Eva Marita; Fiske, Peder; Karlsson, Sten (Journal article; Peer reviewed, 2021)Genetic methods for the estimation of population size can be powerful alternatives to conventional methods. Close-kin mark–recapture (CKMR) is based on the principles of conventional mark–recapture, but instead of being ... -
Domesticated escapees on the run: The second-generation monitoring programme reports the numbers and proportions of farmed Atlantic salmon in >200 Norwegian rivers annually
Glover, Kevin; Urdal, Kurt; Næsje, Tor; Skoglund, Helge; Florø-Larsen, Bjørn; Otterå, Håkon Magne; Fiske, Peder; Heino, Mikko Petteri; Aronsen, Tonje; Sægrov, Harald; Diserud, Ola Håvard; Barlaup, Bjørn Torgeir; Hindar, Kjetil; Bakke, Gunnar O; Solberg, Ingrid; Lo, Håvard; Solberg, Monica Favnebøe; Karlsson, Sten; Skaala, Øystein; Lamberg, Anders; Kanstad-Hanssen, Øyvind; Muladal, Rune; Skilbrei, Ove Tommy; Wennevik, Vidar (Peer reviewed; Journal article, 2019)Norway is the world’s largest producer of farmed Atlantic salmon and is home to ∼400 rivers containing wild salmon populations. Farmed escapees, a reoccurring challenge of all cage-based marine aquaculture, pose a threat ... -
The future looks like the past: Introgression of domesticated Atlantic salmon escapees in a risk assessment framework
Glover, Kevin; Wennevik, Vidar; Hindar, Kjetil; Skaala, Øystein; Fiske, Peder; Solberg, Monica Favnebøe; Diserud, Ola Håvard; Svåsand, Terje; Karlsson, Sten; Berg Andersen, Lasse; Grefsrud, Ellen Sofie (Journal article; Peer reviewed, 2020)Escapes of domesticated fish from aquaculture, followed by interbreeding with wild conspecifics, represent a threat to the genetic integrity and evolutionary trajectory of natural populations. Approximately fifty years of ... -
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 (Journal article; Peer reviewed, 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 ...
