Assessing swimming capacity and schooling behaviour in farmed Atlantic salmon Salmo salar with experimental push-cages
Hvas, Malthe; Folkedal, Ole; Solstorm, David; Vågseth, Tone; Fosse, Jan Olav; Gansel, Lars Christian; Oppedal, Frode (Journal article; Peer reviewed, 2017)The Atlantic salmon aquaculture industry is expanding to more exposed locations that often are characterized by occasional very strong currents. This necessitates new guidelines concerning acceptable animal welfare and a ... -
Effect of temperature on the metabolism, behaviourand oxygen requirements of Sparus aurata
Remen, Mette; Olsen, Rolf Erik; Oppedal, Frode; Thorsheim, Grethe Beate; Folkedal, Ole; Sitjà-Bobadilla, Ariadna; Pérez-Sánchez, Jaume; Nederlof, Marit A. J. (Journal article; Peer reviewed, 2015)We investigated the effect of temperature on the limiting oxygen saturation (LOS) of gilthead sea bream Sparus aurata. This threshold was defined as the % O2 saturation where fish no longer upheld their routine metabolic ... -
Habituation and conditioning in gilthead sea bream (Sparus aurata): Effects of aversive stimuli, reward and social hierarchies
Folkedal, Ole; Fernö, Anders; Nederlof, Marit A. J.; Fosseidengen, Jan Erik; Cerqueira, Marco; Olsen, Rolf Erik; Jonatan, Nilsson (Journal article; Peer reviewed, 2017)To tailor the farming environment to a fish species, we should understand the species-specific responses to stimuli, including the degree of adaption and learning. Groups of gilthead sea bream were given a delay Pavlovian ... -
Novel tag-based method for measuring tailbeat frequency and variations in amplitude in fish
Warren-Myers, F.; Svendsen, Eirik; Føre, Martin; Folkedal, Ole; Oppedal, Frode; Hvas, Malthe (Peer reviewed; Journal article, 2023)The tailbeat frequency (TBF) together with tailbeat amplitude (TBA) of fish are tightly correlated with swimming speed. In addition, these parameters can be used as indicators of metabolic rate and general activity level, ... -
Skin mucus of gilthead sea bream (sparus aurata l.). protein mapping and regulation in chronically stressed fish
Pérez-Sánchez, Jaume; Terova, Genciana; Simó-Mirabet, Paula; Rimoldi, Simona; Folkedal, Ole; Calduch-Giner, Josep Alvar; Olsen, Rolf Erik; Sitjà-Bobadilla, Ariadna (Journal article; Peer reviewed, 2017)The skin mucus of gilthead sea bream was mapped by one-dimensional gel electrophoresis followed by liquid chromatography coupled to high resolution mass spectrometry using a quadrupole time-of-flight mass analyzer.
