A comparative study of diploid versus triploid Atlantic salmon (Salmo salar L.). The effects of rearing temperatures (5, 10 and 15 °C) on raw material characteristics and storage quality
Lerfall, Jørgen; Hasli, Pål Rune; Skare, Even Flønes; Olsen, Rolf Erik; Rotabakk, Bjørn Tore; Roth, Bjørn; Slinde, Erik; Egelandsdal, Bjørg Tordis (Journal article; Peer reviewed, 2017)Several major market operators argue that the current level of knowledge about quality is too scant to justify a switch to a large-scale production of triploid salmon. The aim of the present study was, therefore, to elucidate ... -
Comparative transcriptomics reveals domestication‐associated features of Atlantic salmon lipid metabolism
Jin, Yang; Olsen, Rolf Erik; Harvey, Thomas Nelson; Østensen, Mari-Ann; Li, Keshuai; Santi, Nina; Vadstein, Olav; Bones, Atle M.; Vik, Jon Olav; Sandve, Simen Rød; Olsen, Yngvar (Peer reviewed; Journal article, 2020)Domestication of animals imposes strong targeted selection for desired traits but can also result in unintended selection due to new domestic environments. Atlantic salmon was domesticated in the 1970s and has subsequently ... -
Physiological changes observed in farmed Atlantic salmon (Salmo salar L.) with nephrocalcinosis
Klykken, Christine; Reed, A.K.; Dalum, Alf Seljenes; Olsen, Rolf Erik; Moe, Morten Kaare; Attramadal, Kari; Boissonnot, Lauris Jeannine Ernestine (Peer reviewed; Journal article, 2022)There is a growing concern for fish health and welfare in the salmon industry in Norway. Nephrocalcinosis, described as mineral deposits within the kidney, is increasingly observed. However, little is known about its ... -

The Effect of Osmotic Pressure on Rigor Mortis in Salmonids
Chan, Sherry Stephanie (Master thesis, 2016)Rigor mortis is a natural phenomenon caused by a series of complicated chemical changes in the muscles after the death of an animal. This concept is important especially in meat technology since it affects texture, yield ... -
Transcriptional regulation of lipid metabolism when salmon fry switches from endogenous to exogenous feeding
Jin, Yang; Olsen, Rolf Erik; Østensen, Mari-Ann; Gillard, Gareth Benjamin; Li, Keshuai; Harvey, Thomas Nelson; Santi, Nina; Vadstein, Olav; Vik, Jon Olav; Sandve, Simen Rød; Olsen, Yngvar (Journal article; Peer reviewed, 2018)The onset of first feeding is a critical period for Atlantic salmon (Salmo salar). The fish goes through a dramatic transition, from using the yolk sac as an energy and nutrient resource to rely on exogenous food. However, ...
