Evaluation of genetic effects on wild salmon populations from stock enhancement
Hagen, Ingerid Julie; Ugedal, Ola; Jensen, Arne Johan; Lo, Håvard; Holthe, Espen; Bjøru, Bjørn; Florø-Larsen, Bjørn; Sægrov, Harald; Skoglund, Helge; Karlsson, Sten (Peer reviewed; Journal article, 2020)Many salmonid populations are of conservation concern, and the release of hatchery-produced juveniles is a frequently used measure to alleviate declines and increase harvest opportunities. While such releases may be of ... -
Introgression from farmed escapees affects the full life cycle of wild Atlantic salmon
Bolstad, Geir Hysing; Karlsson, Sten; Hagen, Ingerid Julie; Fiske, Peder; Urdal, Kurt; Sægrov, Harald; Florø-Larsen, Bjørn; Sollien, Vegard Pedersen; Østborg, Gunnel Marie; Diserud, Ola Håvard; Jensen, Arne Johan; Hindar, Kjetil (Peer reviewed; Journal article, 2021)After a half a century of salmon farming, we have yet to understand how the influx of genes from farmed escapees affects the full life history of Atlantic salmon (Salmo salar L.) in the wild. Using scale samples of over ... -
Spatial variation in the evolutionary potential and constraints of basal metabolic rate and body mass in a wild bird
Nafstad, Ådne Messel; Rønning, Bernt; Aase, Kenneth; Ringsby, Thor Harald; Hagen, Ingerid Julie; Ranke, Peter Sjolte; Kvalnes, Thomas; Stawski, Clare; Räsänen, Katja; Sæther, Bernt-Erik; Muff, Stefanie; Jensen, Henrik (Peer reviewed; Journal article, 2023)An organism's energy budget is strongly related to resource consumption, performance, and fitness. Hence, understanding the evolution of key energetic traits, such as basal metabolic rate (BMR), in natural populations is ... -
Supplementary stocking selects for domesticated genotypes
Hagen, Ingerid Julie; Jensen, Arne Johan; Bolstad, Geir Hysing; Diserud, Ola Håvard; Hindar, Kjetil; Lo, Håvard; Karlsson, Sten (Journal article; Peer reviewed, 2019)Stocking of hatchery produced fish is common practise to mitigate declines in natural populations and may have unwanted genetic consequences. Here we describe a novel phenomenon arising where broodstock used for stocking ...
