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 ... -
Fish welfare based classification method of ocean current speeds at aquaculture sites
Jónsdóttir, Kristbjörg Edda; Hvas, Malthe; Alfredsen, Jo Arve; Føre, Martin; Alver, Morten; Bjelland, Hans Vanhauwaert; Oppedal, Frode (Journal article; Peer reviewed, 2019)ABSTRACT: A major trend in marine aquaculture is to move production to more exposed sites with occasionally rough ocean current events. However, it is unclear whether fish will thrive in these extreme environments, since ... -
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, ...
