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 ... -
Exogenous growth hormone (GH) increases dimension and reduces strength of vertebrae in Atlantic salmon (Salmo salar)
Fjelldal, Per Gunnar; Saito, Takaya; Björnsson, Björn Thrandur; Yin, Peng; Hansen, Tom Johnny; Pedersen, Audun Østby; Hamre, Kristin (Peer reviewed; Journal article, 2024)Growth hormone (GH) administration increases bone strength in rats, mainly through alterations of the dimensional proportions of vertebrae. However, similar knowledge is lacking in other clades. In order to pursue this, ... -
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, ... -
The initiation of puberty in Atlantic salmon brings about large changes in testicular gene expression that are modulated by the energy status
Crespo, Diego; Bogerd, Jan; Sambroni, Elisabeth; LeGac, Florence; Andersson, Eva; Edvardsen, Rolf; Bergman, Elisabeth Jonsson; Björnsson, Björn Thrandur; Taranger, Geir Lasse; Schulz, Rüdiger W. (Journal article; Peer reviewed, 2019)Background When puberty starts before males reach harvest size, animal welfare and sustainability issues occur in Atlantic salmon (Salmo salar) aquaculture. Hallmarks of male puberty are an increased proliferation activity ...
