Growth, feed utilization, health and biometric parameters in Atlantic salmon (Salmo salar L.) - Influence of dietary protein-to-lipid ratio and body fat status
Dessen, Jens-Erik (PhD Thesis;2018:103, Doctoral thesis, 2018)Today, commercial diets for large farmed Atlantic salmon (Salmo salar L.) commonly contain 30-35 % protein and 35-39 % lipids, i.e. a ratio of protein-to-lipids below 1. Such energy dense diets have generally been shown ... -

Increased protein-to-lipid ratio in energy dense diets improves slaughter yields and muscle thickness of different weight classes of farmed Atlantic salmon (Salmo salar L.)
Weihe, Runi; Dessen, Jens-Erik; Arge, Regin; Thomassen, Magny Sissel S.; Hatlen, Bjarne; Rørvik, Kjell-Arne (Journal article; Peer reviewed, 2019) -
Influence of dietary tetradecylthioacetic acid (TTA) on lipid content and fatty acid composition in liver of 1+ Atlantic salmon (Salmo salar L.) and sex-specific differences in muscle fat provoked by TTA.
Dessen, Jens-Erik (Master thesis, 2011-11-03)Tetradesyltioeddiksyre (TTA) er en modifisert fettsyre som har vist seg å ha en rekke biologiske og fysiologiske effekter hos pattedyr og fisk. I forsøk med Atlantisk laks (Salmo salar L.) har tilsetting av TTA i fôret ... -
Influence of feed ration size on somatic and muscle growth in landlocked dwarf and farmed Atlantic salmon Salmo salar
Andersen, Øivind; Vieira, Vera; Dessen, Jens-Erik; Johnston, Ian A. (Journal article; Peer reviewed, 2019) -
Low body fat content prior to declining day length in the autumn significantly increased growth and reduced weight dispersion in farmed Atlantic salmon Salmo salar L.

I dag har hver femte filet slike flekker som i hovedsak er opp til 3 cm i diameter og lokalisert til filetens bukområde. Store ryggflekker har ... -
Phospholipid and LC-PUFA metabolism in Atlantic salmon (Salmo salar) testes during sexual maturation
Bogevik, André Sture; Hayman, Edward S.; Bjerke, Målfrid Tofteberg; Dessen, Jens-Erik; Rørvik, Kjell-Arne; Luckenbach, J. Adam (Peer reviewed; Journal article, 2020)The importance of dietary lipids in male reproduction are not as well understood as in females, in which dietary lipids, such as phospholipids (PL) and associated fatty acids (FA), are important structural components of ... -
Rib abnormalities and their association with focal dark spots in Atlantic salmon fillets
Jiménez-Guerrero, Raúl; Bæverfjord, Grete; Evensen, Øystein; Hamre, Kristin; Larsson, Thomas; Dessen, Jens-Erik; Gannestad, Kjellrun Hoås; Mørkøre, Turid (Peer reviewed; Journal article, 2022) -
Smoltification, seawater performance, and maturation in Atlantic salmon (Salmo salar) fed different fat levels
Mota, Vasco C.; Verstege, Gerhardus C.; Striberny, Anja; Lutfi Royo, Esmail; Dessen, Jens-Erik; Sveen, Lene; Burgerhout, Erik; Bou, Marta (Peer reviewed; Journal article, 2024)The use of recirculating aquaculture systems (RAS) to produce Atlantic salmon smolts has resulted in exceptionally high fish growth rates.

In this study, an event of sudden mortality ...
