Sudden exposure to warm water causes Instant behavioural responses indicative of nociception or pain in Atlantic salmon
Nilsson, Jonatan; Moltumyr, Lene; Madaro, Angelico; Kristiansen, Tore S; Gåsnes, Siri Kristine; Mejdell, Cecilie Marie; Gismervik, Kristine; Stien, Lars Helge (Journal article; Peer reviewed, 2019)Thermal treatment has become the most used delousing method in salmonid aquaculture. However, concerns have been raised about it being painful for the fish. We studied the behavioural response of Atlantic salmon acclimated ... -
Thermal injuries in Atlantic salmon in a pilot Laboratory trial
Gismervik, Kristine; Gåsnes, Siri Kristine; Gu, Jinni; Stien, Lars Helge; Madaro, Angelico; Nilsson, Jonatan (Peer reviewed; Journal article, 2019)Thermal delousing is a new method for removing sea lice from farmed Atlantic salmon (Salmo salar L). We investigated thermally-related tissue injuries in Atlantic salmon in a pilot laboratory trial to describe the acute ... -
Triploidy leads to a mismatch of smoltification biomarkers in the gill and differences in the optimal salinity for post-smolt growth in Atlantic salmon
de Fonseka, Raneesha; Fjelldal, Per Gunnar; Sambraus, Florian; Nilsen, Tom Ole; Remø, Sofie C.; Stien, Lars Helge; Reinardy, Helena; Madaro, Angelico; Hansen, Tom Johnny; Fraser, Thomas (Peer reviewed; Journal article, 2021)Sterile triploid Atlantic salmon (Salmo salar) show inconsistent seawater grow-out, but the reason why remains unclear. The purpose of this study was to determine the salinity optima of triploid post-smolts. Diploids and ... -
Vgll3 regulates the timing of puberty in farmed Atlantic salmon, but it does not explain family discordance in male maturation following different smolt production regimes
Fraser, Thomas; Tjølsen, Aslak; Madaro, Angelico; Hansen, Tom Johnny; Fjelldal, Per Gunnar (Peer reviewed; Journal article, 2024)Atlantic salmon (Salmo salar) farming is moving towards extended periods of land-based production to minimise the time at sea, but this increases the risk of unwanted male sexual maturation. As the timing of puberty is ... -
Warm water treatment increased mortality risk in salmon
Bui, Samantha; Madaro, Angelico; Nilsson, Jonatan; Fjelldal, Per Gunnar; Iversen, Martin Haugmo; Brinchmann, Monica Fengsrud; Venås, Birger; Schrøder, Merete Bjørgan; Stien, Lars Helge (Peer reviewed; Journal article, 2022)Thermal treatment is a controversial method to control sea lice in the Atlantic salmon farming industry. This study aimed to complement the growing evidence base to document the impact of thermal treatments on salmon ...
