Algal oil gives control of long-chain omega-3 levels in full-cycle production of Atlantic salmon, without detriment to zootechnical performance and sensory characteristics
Santigosa, Ester; Olsen, Rolf-Erik; Madaro, Angelico; Verlhac Trichet, Viviane; Carr, Ian (Peer reviewed; Journal article, 2023)The levels of eicosapentaenoic (EPA) and docosahexaenoic (DHA) in salmon fillets have decreased because of the progressive replacement of fish oil (FO). This study contributes to enabling the sustainable growth of aquaculture ... -
Comparing physiological responses of acute and chronically stressed diploid and triploid Atlantic salmon (Salmo salar)
Madaro, Angelico; Lai, Floriana; Fjelldal, Per Gunnar; Hansen, Tom Johnny; Gelebart, Virginie; Muren, Brynjar; Rønnestad, Ivar; Olsen, Rolf-Erik; Stien, Lars Helge (Peer reviewed; Journal article, 2024)We compared the performance and physiological response of diploid and triploid Atlantic salmon (Salmo salar) following 21 days of either unpredictable chronic stress (UCS) or no disturbance (control). Thereafter, all four ... -

Environmentally driven changes in Atlantic salmon oxidative status interact with physiological performance
Yin, Peng; Saito, Takaya; Fjelldal, Per Gunnar; Björnsson, Björn Thrandur; Remø, Sofie C.; Sharma, Sandeep; Olsen, Rolf-Erik; Hamre, Kristin (Peer reviewed; Journal article, 2024)Farmed Atlantic salmon in sea cages experience natural seasonal changes in seawater temperature and photoperiod. Atlantic salmon have more oxidized tissues in spring and early summer, and this corresponds to the period of ... -
Seasonal Changes in Photoperiod: Effects on Growth and Redox Signaling Patterns in Atlantic Salmon Postsmolts
Yin, Peng; Saito, Takaya; Fjelldal, Per Gunnar; Björnsson, Björn Thrandur; Remø, Sofie C.; Hansen, Tom Johnny; Sharma, Sandeep; Olsen, Rolf-Erik; Hamre, Kristin (Peer reviewed; Journal article, 2023)Farmed Atlantic salmon reared under natural seasonal changes in sea-cages had an elevated consumption of antioxidants during spring. It is, however, unclear if this response was caused by the increase in day length, ... -
