Changes in daylength and temperature from April until August for Atlantic salmon (Salmo salar) reared in sea cages, increase growth, and may cause consumption of antioxidants, onset of cataracts and increased oxidation of fillet astaxanthin
Hamre, Kristin; Micallef, Giulia; Hillestad, Marie; Johansen, Johan; Remø, Sofie c; Zhang, Wuxiao; Ødegård, Elisabeth Rasmussen; Araujo, Hernandez Pedro W; Prabhu, P. Antony Jesu; Waagbø, Rune (Peer reviewed; Journal article, 2022)The hypothesis of the present study was that increased growth in spring, stimulated by increasing temperature and daylength, leads to oxidative stress in Atlantic salmon with accumulation of oxidation products in the tissues ... -
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 ... -
Oksidativt stress, vårdropp i pigmentering og produksjonslidelser hos laks
Hamre, Kristin; Remø, Sofie C.; Ørnsrud, Robin; Oveland, Eystein; Merel, Sylvain; Waagbø, Rune; Micallef, Giulia; Hillestad, Marie; Johansen, Johan (Rapport fra havforskningen;2019 - 16, Research report, 2019)I lakseoppdrett opplever man noen ganger en reduksjon i pigmentering av fileten i forbindelse med økt vekst i vårsesongen når temperatur og daglengde øker. I EU-prosjektet ARRAINA fant vi økt oksidativ status i fisk samplet ... -
Safe limits of selenomethionine and selenite supplementation to plant-based Atlantic salmon feeds
Berntssen, Marc; Betancor, Mónica B.; Caballero, María José; Hillestad, Marie; Rasinger, Josef Daniel; Hamre, Kristin; Sele, Veronika; Amlund, Heidi; Ørnsrud, Robin (Journal article; Peer reviewed, 2018)The use of plant-based feeds warrants the supplementation with selenium (Se) to cover the requirement for Atlantic salmon. Depending on its chemical form, Se is a trace element with a narrow range between requirement and ... -
Validering av optimale mikronæringsstoff-nivå i laksefôr - ASSESSFEED
Hamre, Kristin; Taylor, John F.; Silva, Joanna; Lock, Erik-Jan; Johansen, Johan; Hillestad, Marie; Conceição, Luís E.C.; Tocher, Douglas R.; Espe, Marit; Bjørnevik, Marit; Hemre, Gro Ingunn (Rapport fra havforskningen;21-2018, Research report, 2018)ASSESSFEED er et prosjekt utgått fra EU-prosjektet ARRAINA, med målsetning å validere nye anbefalinger for tilsetning av mikronæringsstoffer, særlig vannløselige vitaminer, i laksefôr. Det ble kjørt et fôingsforsøk der ...
