An oil containing EPA and DHA from transgenic Camelina sativa to replace marine fish oil in feeds for Atlantic salmon (Salmo salar L.): Effects on intestinal transcriptome, histology, tissue fatty acid profiles and plasma biochemistry
Betancor, Monica B; Li, Keshuai; Sprague, Matthew; Bardal, Tora; Sayanova, Olga; Usher, Sarah; Han, Lihua; Måsøval, Kjell; Torrissen, Ole; Napier, Johnathan; Tocher, Douglas R.; Olsen, Rolf Erik (Peer reviewed; Journal article, 2017) -
Can mesopelagic mixed layers be used as feed source for salmon aquaculture ?
Olsen, Rolf Erik; Strand, Espen; Melle, Webjørn Raunsgård; Nørstebø, Jo Trelvik; Lall, Santosh P.; Tocher, Douglas R.; Sprague, Matthew (Journal article; Peer reviewed, 2019)Salmon aquaculture is in great need of good quality balanced protein and lipid sources, particularly marine omega-3 (n-3) long-chain polyunsaturated fatty acids (LC-PUFA), to sustain a further development of the industry. ... -
Dietary micronutrient composition affects fillet texture and muscle cell size in Atlantic salmon (Salmo salar)
Hamre, Kristin; Bjørnevik, Marit; Espe, Marit; Conceição, Luis E. C.; Johansen, Johan; Silva, Joana; Hillestad, Marie; Prabhu, P. Antony Jesu; Taylor, John F.; Tocher, Douglas R.; Lock, Erik-Jan; Hemre, Gro Ingunn (Peer reviewed; Journal article, 2020)During the past 20 years, plant ingredients have taken over as the main constituents in feed for Atlantic salmon. This has changed the nutrient composition of the feeds, the bioavailability of nutrients and perhaps nutrient ... -
Endogenous production of n-3 long-chain PUFA from first feeding and the influence of dietary linoleic acid and the α-linolenic:linoleic ratio in Atlantic salmon (Salmo salar)
Sprague, Matthew; Xu, Gong; Betancor, Monica B; Olsen, Rolf Erik; Torrissen, Ole; Glencross, Brett D.; Tocher, Douglas R. (Journal article; Peer reviewed, 2019)Atlantic salmon (Salmo salar) possess enzymes required for the endogenous biosynthesis of n-3 long-chain PUFA (LC-PUFA), EPA and DHA, from α-linolenic acid (ALA). Linoleic acid (LA) competes with ALA for LC-PUFA biosynthesis ... -
Impact of dietary carbohydrate/protein ratio on hepatic metabolism in land-locked Atlantic salmon (Salmo salar L.)
Betancor, Mónica B.; Olsen, Rolf Erik; Marandel, Lucie; Skulstad, Ole Fredrik; Madaro, Angelico; Tocher, Douglas R.; Panserat, Stephane (Journal article; Peer reviewed, 2018)A common-garden experiment was carried out to compare two genetically distinct strains of Atlantic salmon (Salmo salar) fed diets with either high (CHO) or low (NoCHO) digestible carbohydrate (starch). Twenty salmon from ... -
Micronutrient supplementation affects DNA methylation in male gonads with potential intergenerational epigenetic inheritance involving the embryonic development through glutamate receptor-associated genes
Saito, Takaya; Whatmore, Paul; Taylor, John F.; Fernandes, Jorge Manuel de Oliveira; Adam, Anne-Catrin; Tocher, Douglas R.; Espe, Marit; Skjærven, Kaja Helvik (Peer reviewed; Journal article, 2022)DNA methylation has an important role in intergenerational inheritance. An increasing number of studies have reported evidence of germline inheritance of DNA methylation induced by nutritional signals in mammals. Vitamins ... -
Micronutrient supplementation affects transcriptional and epigenetic regulation of lipid metabolism in a dose-dependent manner
Saito, Takaya; Whatmore, Paul; Taylor, John F.; Fernandes, Jorge Manuel de Oliveira; Adam, Anne-Catrin; Tocher, Douglas R.; Espe, Marit; Skjærven, Kaja Helvik (Peer reviewed; Journal article, 2020) -
Oil from transgenic Camelina sativa containing over 25 % n-3 long-chain PUFA as the major lipid source in feed for Atlantic salmon (Salmo salar)
Betancor, Mónica B.; Li, Keshuai; Bucerzan, Valentin S.; Sprague, Matthew; Sayanova, Olga; Usher, Sarah; Han, Lihua; Norambuena, Fernando; Torrissen, Ole; Napier, Johnathan A.; Tocher, Douglas R.; Olsen, Rolf Erik (Journal article; Peer reviewed, 2018)Facing a bottleneck in the growth of aquaculture, and a gap in the supply and demand of the highly beneficial n-3 long-chain PUFA (LC-PUFA), sustainable alternatives to traditional marine-based feeds are required. Therefore, ... -
Risk assessment of the use of alternative animal and plant raw material resources in aquaculture feeds
Glencross, Brett D.; Baily, Johanna; Berntssen, Marc; Hardy, Ronald; MacKenzie, Simon; Tocher, Douglas R. (Journal article; Peer reviewed, 2019)A wide range of raw materials are now used routinely in aquaculture feeds throughout the world, primarily to supply protein and energy in the form of lipid from edible oils. Protein meals and oils used can generally be ... -
