Prabhu, P. Antony Jesu; Fjelldal, Per Gunnar; Remø, Sofie C.; Selvam, Chandrasekar; Hamre, Kristin; Espe, Marit; Holen, Elisabeth; Skjærven, Kaja Helvik; Vikså, Vibeke; Subramanian, Saravanan; Schrama, Johan W.; Sissener, Nini (Peer reviewed; Journal article, 2022)Dietary electrolyte balance is the equilibrium of monovalent cations and anions that influence the acid-base balance of the feed (dEB = Na + K − Cl, mEq kg−1). Dietary electrolytes/minerals can influence the physiological ... -

Increasing dietary n-6 FA while keeping n-3 FA stable decreases EPA in polar lipids of farmed Atlantic salmon (Salmo salar)
Hundal, Bjørg Kristine; Liland, Nina Sylvia; Rosenlund, Grethe; Bou, Marta; Stubhaug, Ingunn; Sissener, Nini (Peer reviewed; Journal article, 2020)There is an increased use of vegetable oils containing n-6 fatty acids (FA) in aquafeeds, and several trials indicate that there might be an increased requirement of EPA and DHA for Atlantic salmon when they are fed higher ... -
Increasing the dietary n-6/n-3 ratio alters the hepatic eicosanoid production after acute stress in Atlantic salmon (Salmo salar)
Hundal, Bjørg Kristine; Liland, Nina Sylvia; Rosenlund, Grethe; Höglund, Erik; Araujo, Pedro; Stubhaug, Ingunn; Sissener, Nini (Peer reviewed; Journal article, 2021)Earlier studies have indicated that a high inclusion of n-6 fatty acids (FA) in feeds for Atlantic salmon can affect the stress response. To test this hypothesis, Atlantic salmon (Salmo salar) were fed diets containing ... -
Intracellular trafficking of fatty acids in the fish intestinal epithelial cell line RTgutGC
Selvam, Chandrasekar; Saito, Takaya; Sissener, Nini; Prabhu, P. Antony Jesu; Sæle, Øystein (Peer reviewed; Journal article, 2022)The shift towards higher inclusion of vegetable oils (VOs) in aquafeeds has resulted in major changes in dietary fatty acid composition, especially increased amounts of monounsaturated fatty acids (MUFAs) and decreased ... -
Long-term feeding of Atlantic salmon with varying levels of dietary EPA+DHA alters the mineral status, but does not affect the stress responses after mechanical delousing stress
Selvam, Chandrasekar; Prabhu, P. Antony Jesu; Lutfi Royo, Esmail; Sigholt, Trygve; Norberg, Birgitta; Bæverfjord, Grete; Rosenlund, Grethe; Ruyter, Bente Synnøve; Sissener, Nini (Peer reviewed; Journal article, 2022)Atlantic salmon were fed diets containing graded levels of EPA + DHA (1·0, 1·3, 1·6 and 3·5 % in the diet) and one diet with 1·3 % of EPA + DHA with reduced total fat content. Fish were reared in sea cages from about 275 ... -
