    • Atlantic salmon populations reveal adaptive divergence of immune related genes - a duplicated genome under selection 

      Kjærner-Semb, Erik Nordtorp; Ayllon, Fernando; Furmanek, Tomasz; Wennevik, Vidar; Dahle, Geir; Niemelä, Eero; Ozerov, Mikhail; Vähä, Juha-Pekka; Glover, Kevin; Rubin, Carl J.; Wargelius, Anna; Edvardsen, Rolf (BioMed Central, 2016-08-11)
      Background: Populations of Atlantic salmon display highly significant genetic differences with unresolved molecular basis. These differences may result from separate postglacial colonization patterns, diversifying natural ...

    • Biogeography of the fish pathogen Aeromonas salmonicida inferred by vapA genotyping 

      Gulla, Snorre; Bayliss, Sion; Björnsdóttir, Bryndís; Dalsgaard, Inger; Haenen, Olga; Jansson, Eva; McCarthy, Una; Scholz, Felix; Vercauteren, Maaike; Verner-Jeffreys, David; Welch, Tim; Wiklund, Tom; Colquhoun, Duncan John (Oxford University Press, 2019-04-12)
      A recently described typing system based on sequence variation in the virulence array protein (vapA) gene, encoding the A-layer surface protein array, allows unambiguous subtyping of Aeromonas salmonicida. In the present ...

    • 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 (Elsevier, 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 ...

    • Combining biochemical methods to trace organic effluent from fish farms 

      Woodcock, Skye; Troedsson, Christofer; Strohmeier, Tore; Balseiro Vigo, Pablo; Skaar, Katrine Sandnes; Strand, Øivind (Inter-Research, 2017)
      The substitution of fish oils and fish meal with terrestrial components in the diets of farmed fin-fish offers a unique opportunity to trace organic effluents from fin-fish aquaculture into the marine environment. In this ...

    • Fast water currents reduce production performance of post-smolt Atlantic salmon Salmo salar 

      Solstorm, Frida; Solstorm, David; Oppedal, Frode; Fernø, Anders; Fraser, Thomas; Olsen, Rolf Erik (Inter-Research, 2015-09-17)
      In the future, an increasing number of salmon farms may be located in areas with fast water current velocity due to limited availability of more sheltered locations. However, there is little information as to how fast ...

    • 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 (Springer, 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 ...

    • Infection dynamics and tissue tropism of Parvicapsula pseudobranchicola (Myxozoa: Myxosporea) in farmed Atlantic salmon (Salmo salar) 

      Nylund, Are; Hansen, Haakon; Brevik, Øyvind Jakobsen; Hustoft, Håvard; Markussen, Turhan; Plarre, Heidrun; Karlsbakk, Egil (Springer Nature, 2018-01-06)
      Background The myxosporean parasite Parvicapsula pseudobranchicola commonly infects farmed Atlantic salmon in northern Norway. Heavy infections are associated with pseudobranch lesions, runting and mortality in the salmon ...

    • The influence of vgll3 genotypes on sea age at maturity is altered in farmed mowi strain Atlantic salmon 

      Ayllon, Fernando; Solberg, Monica Favnebøe; Glover, Kevin; Mohammadi, Faezeh; Kjærner-Semb, Erik Nordtorp; Fjelldal, Per Gunnar; Andersson, Eva; Hansen, Tom Johnny; Edvardsen, Rolf; Wargelius, Anna (BioMed Central (BMC), 2019-05-06)
      Background: In Atlantic salmon in the wild, age at maturity is strongly influenced by the vgll3 locus. Under farming conditions, light, temperature and feeding regimes are known significantly advance or delay age at ...

    • Judging a salmon by its spots: Environmental variation is the primary determinant of spot patterns in Salmo salar 

      Jørgensen, Katarina Mariann; Solberg, Monica Favnebøe; Besnier, Francois; Thorsen, Anders; Fjelldal, Per Gunnar; Skaala, Øystein; Malde, Ketil; Glover, Kevin (BioMed Central, 2018-04-12)
      Background. In fish, morphological colour changes occur from variations in pigment concentrations and in the morphology, density, and distribution of chromatophores in the skin. However, the underlying mechanisms remain ...

    • Overvåkingsprogram og kompetansehevingstiltak knyttet til vannkvalitet og fiskehelse i marine yngel- og settefiskanlegg (MarinVest) 

      Hess-Erga, Ole-Kristian; Johannessen, Torill Vik; Åtland, Åse (Norsk institutt for vannforskning, 2015)
      Prosjektet «Overvåkingsprogram og kompetansehevingstiltak knyttet til vannkvalitet og fiskehelse i marine yngel- og settefiskanlegg (MarinVest)».har blitt utført i samarbeid med industrideltagerne Sterling White Halibut ...
