      Most Atlantic salmon (Salmo salar L.) populations follow an anadromous life cycle, spending early life in freshwater, migrating to the sea for feeding, and returning to rivers to spawn. At the end of the last ice age ~10,000 ...

    • Development of supermale and all-male Atlantic salmon to research the vgll3 allele - puberty link 

      Fjelldal, Per Gunnar; Hansen, Tom Johnny; Wargelius, Anna; Ayllon, Fernando; Glover, Kevin Alan; Schulz, Rüdiger W.; Fraser, Thomas (Peer reviewed; Journal article, 2020)
      Farmed Atlantic salmon are one of the most economically significant global aquaculture products. Early sexual maturation of farmed males represents a significant challenge to this industry and has been linked with the vgll3 ...

    • Epistatic regulation of growth in Atlantic salmon revealed: a QTL study performed on the domesticated-wild interface

      Quantitative traits are typically considered to be under additive genetic control. Although there are indications that non-additive factors have the potential to contribute to trait variation, experimental demonstration ...

    • Evolutionary drivers of kype size in atlantic salmon (salmo salar): domestication, age and genetics 

      Perry, William; Solberg, Monica Favnebøe; Besnier, Francois; Dyrhovden, Lise; Matre, Ivar Helge; Fjelldal, Per Gunnar; Ayllon, Fernando; Creer, Simon; Llewellyn, Martin; Taylor, Martin I.; Carvalho, Gary; Glover, Kevin (Journal article; Peer reviewed, 2019)
      The diversity of reproduction and associated mating patterns in Atlantic salmon (Salmo salar) has long captivated evolutionary biologists. Salmo salar exhibit strategies involving migration, bold mating behaviours and ...

    • Genetic study reveals local differentiation persisting in the face of high connectivity and a genomic inversion likely linked with sexual antagonism in a common marine fish 

      Jansson, Eeva; André, Carl; Quintela, Maria; Halvorsen, Kim Aleksander Tallaksen; Besnier, Francois; Ayllon, Fernando; Faust, Ellika; Knutsen, Halvor; Strand, Åsa; Glover, Kevin Alan (Peer reviewed; Journal article, 2023)
