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 ... -
Higher mortality of the less suitable brown trout host compared to the principal Atlantic salmon host when infested with freshwater pearl mussel (Margaritifera margaritifera) glochidia
Marwaha, Janhavi; Jakobsen, Per; Karlsson, Sten; Larsen, Bjørn Mejdell; Wacker, Sebastian (Journal article; Peer reviewed, 2021)The freshwater pearl mussel (Margaritifera margaritifera) is a highly host-specific parasite, with an obligate parasitic stage on salmonid fish. Atlantic salmon (Salmo salar) and brown trout (Salmo trutta f. trutta and ... -
Multiple paternity promotes genetic diversity in captive breeding of a freshwater mussel
Wacker, Sebastian; Larsen, Bjørn Mejdell; Jakobsen, Per Johan; Karlsson, Sten (Peer reviewed; Journal article, 2019)Captive breeding can be an important supplement to habitat restoration in the conservation of threatened species. Careful choice of breeding regimes and genetic monitoring are essential to maintain genetic integrity and ...
