Increasing dietary levels of the omega-3 long-chain polyunsaturated fatty acids, EPA and DHA, improves the growth, welfare, robustness, and fillet quality of Atlantic salmon in sea cages
Lutfi Royo, Esmail; Berge, Gerd Marit; Bæverfjord, Grete; Sigholt, Trygve; Bou, Marta; Larsson, Thomas; Mørkøre, Turid; Evensen, Øystein; Sissener, Nini; Rosenlund, Grethe; Sveen, Lene; Østbye, Tone-Kari K; Ruyter, Bente Synnøve (Peer reviewed; Journal article, 2022)The present study evaluated the effects of increasing the dietary levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in Atlantic salmon (Salmo salar) reared in sea cages, in terms of growth performance, ... -
Intestinal health in Atlantic salmon post-smolt (Salmo salar) when fed low- and high HUFA diets
Løvmo, Signe Dille; Sundh, Henrik; Whatmore, Paul; Nordvi, Malene Fosse; Sigholt, Trygve; Madaro, Angelico; Bardal, Tora; Olsen, Rolf Erik (Peer reviewed; Journal article, 2022)It is well established that farmed Atlantic salmon (Salmo salar) need n3-highly unsaturated fatty acids (HUFA) in their diet to thrive and grow. However, the biological functions to the individual HUFAs may differ, implying ... -
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 ... -
Low intestinal inflammation model (HP48) in Atlantic salmon (Salmo salar) and inflammatory mitigation by Bactocell
Nordvi, Malene Fosse; Løvmo, Signe Dille; Whatmore, Paul; Sundh, Henrik; Sigholt, Trygve; Olsen, Rolf Erik (Peer reviewed; Journal article, 2022)Moderate levels of intestinal damage and inflammation are often seen in intensive fish aquaculture. The causes may be due to antinutrients from plant meals, stress or other causes. There is currently a lack of good models ... -
A Piece of the Puzzle—Possible Mechanisms for Why Low Dietary EPA and DHA Cause Hepatic Lipid Accumulation in Atlantic Salmon (Salmo salar)
Hundal, Bjørg Kristine; Lutfi Royo, Esmail; Sigholt, Trygve; Rosenlund, Grethe; Liland, Nina Sylvia; Glencross, Brett; Sissener, Nini (Peer reviewed; Journal article, 2022)The present study aimed at elucidating the effects of graded levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on the hepatic metabolic health of Atlantic salmon reared in sea cages. Diets containing 10, ...
