A comparative study of the physiological responses of chronically stressed diploid and triploid Atlantic salmon (Salmo salar)
Muren, Brynjar (Master thesis, 2022)Rømt oppdrettslaks (Salmo salar) regnes for å være en av de største truslene som påføres ville populasjoner av Atlantisk laks grunnet introgressiv hybridisering. Dette kan unngås ved å indusere sterilitet i oppdrettslaksen, ... -
Acute stress response on Atlantic salmon: a time-course study of the effects on plasma metabolites, mucus cortisol levels, and head kidney transcriptome profile
Madaro, Angelico; Nilsson, Jonatan; Whatmore, Paul; Roh, HyeongJin; Grove, Søren; Stien, Lars Helge; Olsen, Rolf Erik (Peer reviewed; Journal article, 2022)Farmed Atlantic salmon (Salmo salar) welfare and performance can be strongly influenced by stress episodes caused by handling during farming practices. To better understand the changes occurring after an acute stress ... -
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 ... -
Coping with a changing environment: The effects of early life stress
Vindas, Marco Antonio; Madaro, Angelico; Fraser, Thomas; Höglund, Erik; Olsen, Rolf Erik; Øverli, Øyvind; Kristiansen, Tore S (Peer reviewed; Journal article, 2016)Ongoing rapid domestication of Atlantic salmon implies that individuals are subjected to evolutionarily novel stressors encountered under conditions of artificial rearing, requiring new levels and directions of flexibility ... -
CRISPR/Cas9-mediated editing of Δ5 and Δ6 desaturases impairs Δ8-desaturation and docosahexaenoic acid synthesis in Atlantic salmon (Salmo salar L.)
Datsomor, Alex Kojo; Olsen, Rolf Erik; Madaro, Angelico; Bones, Atle M.; Edvardsen, Rolf Brudvik; Wargelius, Anna; Winge, Per (Journal article; Peer reviewed, 2019)The in vivo functions of Atlantic salmon fatty acyl desaturases (fads2), Δ6fads2-a, Δ6fads2-b, Δ6fads2-c and Δ5fads2 in long chain polyunsaturated fatty acid (LC-PUFA) synthesis in salmon and fish in general remains to be ... -
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 ... -
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 ... -
Mid and hindgut transcriptome profiling analysis of Atlantic salmon (Salmon salar) under unpredictable chronic stress
Løvmo, Signe Dille; Madaro, Angelico; Whatmore, Paul; Bardal, Tora; Østensen, Mari-Ann; Sandve, Simen Rød; Olsen, Rolf Erik (Peer reviewed; Journal article, 2020)The intestinal epithelium is a selectively permeable barrier for nutrients, electrolytes and water, while maintaining effective protection against pathogens. Combinations of stressors throughout an animal's life, especially ... -
Molecular Mechanism Involved in Carotenoid Metabolism in Post-Smolt Atlantic Salmon: Astaxanthin Metabolism During Flesh Pigmentation and Its Antioxidant Properties
Schmeisser, Jerome; Verlac-Trichet, Viviane; Madaro, Angelico; Lall, Santosh P.; Torrissen, Ole; Olsen, Rolf Erik (Peer reviewed; Journal article, 2021)A better understanding of carotenoid dynamics (transport, absorption, metabolism, and deposition) is essential to develop a better strategy to improve astaxanthin (Ax) retention in muscle of Atlantic salmon. To achieve ... -
Red and white chinook salmon (Oncorhynchus tshawytscha): Differences in the transcriptome profile of muscle, liver, and pylorus
Madaro, Angelico; Torrissen, Ole; Whatmore, Paul; Lall, Santosh P.; Schmeisser, Jerome; Verlhac Trichet, Viviane; Olsen, Rolf Erik (Journal article; Peer reviewed, 2020)Astaxanthin (Ax), the main carotenoid responsible for the distinct red flesh color in salmonids (Oncorhynchus, Salvelinus, Salmo, and Parahucho), is added to the diet of farmed fish at a substantial cost. Despite the great ...
