(Journal article; Peer reviewed, 2014-10-26)Background The salmon louse, Lepeophtheirus salmonis, is an ectoparasite of salmonids that causes huge economic losses in salmon farming, and has also been causatively linked with declines of wild salmonid populations. ... -
Identification of quantitative genetic components of fitness variation in farmed, hybrid and native salmon in the wild
Besnier, Francois; Glover, Kevin; Lien, Sigbjørn; Kent, Matthew Peter; Hansen, Michael Möller; Shen, Xia; Skaala, Øystein (Journal article; Peer reviewed, 2015-03-18)Feral animals represent an important problem in many ecosystems due to interbreeding with wild conspecifics. Hybrid offspring from wild and domestic parents are often less adapted to local environment and ultimately, can ... -

However, the underlying mechanisms remain unresolved in ... -
