Genetic screening of farmed Atlantic salmon escapees demonstrates that triploid fish display reduced migration to freshwater
Glover, Kevin; Bos, J. B.; Urdal, Kurt; Madhun, Abdullah Sami; Sørvik, Anne Grete Eide; Unneland, Laila; Seliussen, Bjørghild Breistein; Skaala, Øystein; Skilbrei, Ove; Tang, Y.; Wennevik, Vidar (Journal article; Peer reviewed, 2016-02-09)Each year, hundreds of thousands of farmed Atlantic salmon escape from fish farms into the wild. Some of these escapees enter freshwater, and manage to interbreed with native populations. To hinder further genetic introgression ... -
Growth of wild and domesticated Atlantic cod Gadus morhua reared under semi-commercial conditions
Otterå, Håkon Magne; Heino, Mikko; Sørvik, Anne Grete Eide; Svåsand, Terje; Karlsen, Ørjan; Thorsen, Anders; Glover, Kevin (Journal article; Peer reviewed, 2018)Genetic interactions between farmed escapees and wild fish represent a challenge to environmentally sustainable aquaculture. Breeding programs for Atlantic cod Gadus morhua have been initiated; however, the genetic response ... -
Hybrids between common and Antarctic minke whales are fertile and can back-cross
