Farmed escapees, a reoccurring challenge of all cage-based marine aquaculture, pose a threat ... -
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 Tommy; Tang, Y.; Wennevik, Vidar (Peer reviewed; Journal article, 2016-05)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 ... -
Swimming with the fishes: validating drift diving to identify farmed Atlantic salmon escapees in the wild
Mahlum, Shad Kenneth; Skoglund, Helge; Wiers, Tore; Norman, Eirik; Barlaup, Bjørn Torgeir; Wennevik, Vidar; Glover, Kevin; Urdal, Kurt; Bakke, Gunnar O; Vollset, Knut (Peer reviewed; Journal article, 2019)Escaped farmed Atlantic salmon Salmo salar interbreeding with wild conspecifics represents a threat to the genetic integrity and viability of wild populations. Therefore, it is necessary to accurately quantify escapees in ...
