Sambraus, Florian; Remen, Mette; Olsen, Rolf Erik; Hansen, Tom Johnny; Waagbø, Rune; Torgersen, Thomas; Lock, Erik-Jan; Imsland, Albert; Fraser, Thomas W.K.; Fjelldal, Per Gunnar (Peer reviewed; Journal article, 2018) -
Cleaner Fish Do Not Impact the Pigmentation of Salmon Lice (Lepeophtheirus salmonis) in Commercial Aquaculture Cages
Imsland, Albert; Berg, Jon Petter; Nola, Velimir; Geitung, Lena; Oldham, Tina Marie Wier (Peer reviewed; Journal article, 2023)Salmon lice are one of the biggest challenges to sustainable salmonid aquaculture. The species display high evolutionary potential, which is evident by its development of resistance to numerous chemical compounds used for ... -
Flesh quality of Atlantic salmon smolts reared at different temperatures and photoperiods
Imsland, Albert; Roth, Bjørn; Døskeland, Inge; Fjelldal, Per Gunnar; Stefansson, Sigurd Olav; Handeland, Sigurd O; Mikalsen, Bjørn (Journal article; Peer reviewed, 2019)Possible interactive effects of temperature and photoperiod on flesh quality in Atlantic salmon post‐smolts were studied. Juvenile (initial mean weight 96.0 g ± 3.1 SEM) Atlantic salmon were reared at six different ... -
Interaction of temperature and feed ration on male postsmolt maturation of Atlantic salmon (Salmo salar L.)
Pino Martinez, Enrique; Balseiro Vigo, Pablo; Stefansson, Sigurd Olav; Kaneko, Nobuto; Norberg, Birgitta; Fleming, Mitchell Stewart; Imsland, Albert; Handeland, Sigurd Olav (Peer reviewed; Journal article, 2023)Early maturation of Atlantic salmon male postsmolts is undesirable in aquaculture due to its negative impact on growth, welfare and seawater adaptation, however it is an increasing problem under intensive rearing conditions. ... -
Interaction of temperature and photoperiod on male postsmolt maturation of Atlantic salmon (Salmo salar L.)
Pino Martinez, Enrique; Balseiro Vigo, Pablo; Fleming, Mitchell Stewart; Stefansson, Sigurd Olav; Norberg, Birgitta; Imsland, Albert; Handeland, Sigurd Olav (Peer reviewed; Journal article, 2023)Maturation of Atlantic salmon male postsmolts is a concern in aquaculture due to its increasing occurrence under intensive rearing conditions and its negative impact on growth, welfare and seawater readiness.

Lumpfish Cyclopterus lumpus reproduction: Pituitary gene expression, physiological and morphological changes accompanying gonadal maturation
Andersson, Eva; Denker, Elsa; Norberg, Birgitta; Schulz, Rüdiger W.; Olausson, Sara; Thorsen, Anders; Stefansson, Sigurd Olav; Imsland, Albert (Peer reviewed; Journal article, 2022)Lumpfish is the most important cleanerfish species in Atlantic salmon farming. Detailed information on the gonadal maturation process is a prerequisite for year-round production of juvenile lumpfish. In the present study ... -
