    • Aquaculture-driven evolution of the salmon louse mtDNA genome 

      Rutle, Karoline Hasti; Skern-Mauritzen, Rasmus; Nilsen, Frank; Mateos-Rivera, Alejandro; Sørvik, Anne Grete Eide; Jansson, Eeva; Quintela, Maria; Besnier, Francois; Ayllon, Fernando; Fjørtoft, Helene Børretzen; Glover, Kevin Alan (Journal article; Peer reviewed, 2023)
      Resistance toward the antiparasitic pyrethroid, deltamethrin, is reported in the Atlantic salmon louse (Lepeophtheirus salmonis salmonis), a persistent ectoparasite of farmed and wild salmonids. The resistance mechanism ...

    • Cloned and outbred Atlantic salmon display equal parasite dispersion when infected with the salmon louse 

      Glover, Kevin; Hansen, Tom Johnny; Besnier, Francois; Solberg, Monica Favnebøe; Fjelldal, Per Gunnar; Sørvik, Anne Grete Eide; Dalvin, Sussie; Nilsen, Frank (Peer reviewed; Journal article, 2017-11)
      The salmon louse is an ectoparasitic copepod that infects salmonids in the marine environment. This parasite causes a major economic and biological challenge to the Atlantic salmon farming industry, and efforts to increase ...

    • An extensive common‐garden study with domesticated and wild Atlantic salmon in the wild reveals impact on smolt production and shifts in fitness traits 

      Skaala, Øystein; Besnier, Francois; Borgstrøm, Reidar; Barlaup, Bjørn Torgeir; Sørvik, Anne Grete Eide; Normann, Eirik; Østebø, Britt Iren; Hansen, Michael Møller; Glover, Kevin (Peer reviewed; Journal article, 2019-02-19)
      Interactions between domesticated escapees and wild conspecifics represent a threat to the genetic integrity and fitness of native populations. For Atlantic salmon, the recurrent presence of large numbers of domesticated ...

    • Genetic analysis redraws the management boundaries for the European sprat 

      Kvamme, Cecilie; Bekkevold, Dorte; Nash, Richard David Marriott; Jansson, Eeva; Sørvik, Anne Grete Eide; Taggart, John B.; Skaala, Øystein; Dahle, Geir; Glover, Kevin; Quintela, Maria (Journal article; Peer reviewed, 2020)
      Sustainable fisheries management requires detailed knowledge of population genetic structure. The European sprat is an important commercial fish distributed from Morocco to the Arctic circle, Baltic, Mediterranean, and ...

    • 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 ...

    • Hybrids between common and Antarctic minke whales are fertile and can back-cross 

      Glover, Kevin; Kanda, Naohisa; Haug, Tore; Pastene, Luis A.; Øien, Nils Inge; Seliussen, Bjørghild Breistein; Sørvik, Anne Grete Eide; Skaug, Hans J. (Peer reviewed; Journal article, 2013-04-15)
      Background: Minke whales are separated into two genetically distinct species: the Antarctic minke whale found in the southern hemisphere, and the common minke whale which is cosmopolitan. The common minke whale is further ...

    • Implications for introgression: Has selection for fast growth altered the size threshold for precocious male maturation in domesticated Atlantic salmon? 

      Harvey, Alison C.; Skilbrei, Ove Tommy; Besnier, Francois; Solberg, Monica Favnebøe; Sørvik, Anne Grete Eide; Glover, Kevin (Peer reviewed; Journal article, 2018-12-18)
      Background: Mature male parr (MMP) represent an important alternative life-history strategy in Atlantic salmon populations. Previous studies indicate that the maturation size threshold for male parr varies among wild ...

    • Investigating the frequency of triploid Atlantic salmon in wild Norwegian and Russian populations 

      Jørgensen, Katarina Mariann; Wennevik, Vidar; Sørvik, Anne Grete Eide; Unneland, Laila; Prusov, Sergey; Ayllon, Fernando; Glover, Kevin (Peer reviewed; Journal article, 2018-10-03)
      Background Fish may display variations in ploidy, including three sets of chromosomes, known as triploidy. A recent study revealed a frequency of ~ 2% spontaneous (i.e., non-intentional) triploidy in domesticated Atlantic ...

    • Production and verification of the first Atlantic salmon (Salmo salar L.) clonal lines 

      Hansen, Tom Johnny; Penman, David J.; Glover, Kevin; Fraser, Thomas; Vågseth, Tone; Thorsen, Anders; Sørvik, Anne Grete Eide; Fjelldal, Per Gunnar (Journal article; Peer reviewed, 2020)
      Background In several fish species homozygous and heterozygous clonal lines have been produced using gynogenetic and androgenetic techniques. These lines are standardized and can be reproduced over generations. In rainbow ...
