    • Group Behavioural Responses of Atlantic Salmon (Salmo salar L.) to Light, Infrasound and Sound Stimuli 

      Bui, Samantha; Oppedal, Frode; Korsøen, Øyvind Johan; Sonny, Damien; Dempster, Tim (Journal article; Peer reviewed, 2013-05-17)
      Understanding species-specific flight behaviours is essential in developing methods of guiding fish spatially, and requires knowledge on how groups of fish respond to aversive stimuli. By harnessing their natural behaviours, ...

    • Growth and welfare of submerged Atlantic salmon under continuous lightning 

      Sievers, Michael; Korsøen, Øyvind Johan; Dempster, Timothy David; Fjelldal, Per Gunnar; Kristiansen, Tore S; Folkedal, Ole; Oppedal, Frode (Peer reviewed; Journal article, 2018)
      ABSTRACT: Although surface-based cages dominate the marine finfish aquaculture industry, production issues that arise at the surface such as poor environmental conditions and the presence of parasites has spurred interest ...

    • Hvordan unngå flytere ved heving av torskemerder 

      Korsøen, Øyvind Johan; Fosseidengen, Jan Erik; Dempster, Tim; Stien, Lars Helge; Kristiansen, Tore S. (Havforskningsnytt;Nr. 2 - 2011, Working paper, 2011)
      Oppdrettstorsk tåler en trykkreduksjon på maks 40 % dersom en skal være sikker på at svømmeblæren ikke løfter fisken til overflaten med buken i været. Etter en slik reduksjon av trykket bør det gå minst åtte timer før ...

    • Submerged cage aquaculture of marine fish: a review of the biological challenges and opportunities 

      Sievers, Michael; Korsøen, Øyvind Johan; Warren-Myers, Fletcher; Oppedal, Frode; Macauley, Georgia; Folkedal, Ole; Dempster, Tim (Peer reviewed; Journal article, 2021)
      Surface-based cages are the dominant production technology for the marine finfish aquaculture industry. However, issues such as extreme weather events, poor environmental conditions, interactions with parasites, and conflicts ...

    • Torskeoppdrett i nedsenkede merder? 

      Korsøen, Øyvind Johan; Fosseidengen, Jan Erik; Dempster, Tim; Kristiansen, Tore S. (Journal article, 2011-05)
      På grunn av torskens forkjærlighet for lavere sommertemperaturer og høyere vintertemperaturer enn det man ofte finner i de øverste lagene i vannsøylen, har både kommersielle aktører og forskere forsøkt med oppdrett av ...

    • Towards cod without spawning: artificial continuous light in submerged sea-cages maintains growth and delays sexual maturation for farmed Atlantic cod Gadus morhua 

      Korsøen, Øyvind Johan; Dempster, Tim; Fosseidengen, Jan Erik; Karlsen, Ørjan; Oppedal, Frode; Stien, Lars Helge; Kristiansen, Tore S. (Journal article; Peer reviewed, 2013-06-04)
      Sexual maturation and spawning in sea-cages is a major production and environmental challenge for the Atlantic cod farming industry. Altered photoperiod has arrested sexual maturation in cod kept in indoor or covered ...
