Do background levels of the pesticide pirimiphosmethyl in plant-based aquafeeds affect food safety of farmed Atlantic salmon?
Berntssen, Marc HG; Hoogenveen, Rudolf; Rosenlund, Grethe; Garlito, Borja; Zeilmaker, Marco J. (Peer reviewed; Journal article, 2020)The substitution of fish oil and fishmeal with plant-based ingredients in commercial aquafeeds for Atlantic salmon, may introduce novel contaminants that have not previously been associated with farmed fish. The organophosphate ... -

Impact of dietary level and ratio of n-6 and n-3 fatty acids on disease progression and mRNA expression of immune and inflammatory markers in Atlantic salmon (Salmo salar) challenged with Paramoeba perurans
Selvam, Chandrasekar; Powell, Mark Darryn; Liland, Nina Sylvia; Rosenlund, Grethe; Sissener, Nini (Peer reviewed; Journal article, 2021)The aim of the study was to investigate the influence of dietary level and ratio of n-6/n-3 fatty acids (FA) on growth, disease progression and expression of immune and inflammatory markers in Atlantic salmon (Salmo salar) ... -
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, ... -
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 ... -
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 ... -
