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 ... -
Genetic introgression of farmed salmon in native populations: quantifying the relative influence of population size and frequency of escapees
Heino, Mikko Petteri; Svåsand, Terje; Wennevik, Vidar; Glover, Kevin (Peer reviewed; Journal article, 2015-02-11)Farmed escapees may threaten the genetic integrity of native salmon populations through interbreeding. However, introgression requires survival until maturation, successful reproduction and successful early development. ... -
Half a century of genetic interaction between farmed and wild Atlantic salmon: Status of knowledge and unanswered questions
Glover, Kevin; Solberg, Monica Favnebøe; McGinnity, Phil; Hindar, Kjetil; Verspoor, Eric; Coulson, Mark W.; Hansen, Michael Möller; Araki, Hitoshi; Skaala, Øystein; Svåsand, Terje (Peer reviewed; Journal article, 2017)Atlantic salmon (Salmo salar) is one of the best researched fishes, and its aquaculture plays a global role in the blue revolution. However, since the 1970s, tens of millions of farmed salmon have escaped into the wild. ... -
Modeling fitness changes in wild Atlantic salmon populations faced by spawning intrusion of domesticated escapees
Castellani, Marco; Heino, Mikko Petteri; Gilbey, John; Araki, Hitoshi; Svåsand, Terje; Glover, Kevin (Peer reviewed; Journal article, 2018-07)Genetic interaction between domesticated escapees and wild conspecifics represents a persistent challenge to an environmentally sustainable Atlantic salmon aquaculture industry. We used a recently developed eco‐genetic ... -
Prevalence of piscine orthoreovirus and salmonid alphavirus in sea-caught returning adult Atlantic salmon (Salmo salar L.) in northern Norway
Madhun, Abdullah Sami; Isachsen, Cecilie Helen; Omdal Strandenes, Linn Maren; Einen, Ann Cathrine B.; Mæhle, Stig; Wennevik, Vidar; Niemelä, Eero; Svåsand, Terje; Karlsbakk, Egil (Peer reviewed; Journal article, 2018-05)Heart and skeletal muscle inflammation (HSMI) caused by piscine orthoreovirus (PRV) and pancreas disease (PD) caused by salmonid alphavirus (SAV) are among the most prevalent viral diseases of Atlantic salmon farmed in ...
