The effects of nutritional state, sex and body size on the marine migration behaviour of sea trout
Eldøy, Sindre Håvarstein; Bordeleau, Xavier; Lawrence, M. J.; Thorstad, Eva B.; Finstad, Anders Gravbrøt; Whoriskey, Frederick G.; Crossin, Glenn T; Cooke, Steven J.; Aarestrup, Kim; Rønning, Lars; Sjursen, Aslak Darre; Davidsen, Jan Grimsrud (Peer reviewed; Journal article, 2021)The sea trout (anadromous brown trout Salmo trutta) displays extensive among-individual variation in marine migration behaviour. We studied the migration behaviour of 286 sea trout (27-89 cm) tagged with acoustic transmitters ... -
Effects of sound exposure from a seismic airgun on heart rate, acceleration and depth use in free-swimming Atlantic cod and saithe
Davidsen, Jan Grimsrud; Dong, Hefeng; Linne, Markus; Andersson, Mathias H.; Piper, Adam; Prystay, Tanya S.; Hvam, Eivind B.; Thorstad, Eva Bonsak; Whoriskey, Frederick G.; Cooke, Steven J.; Sjursen, Aslak Darre; Rønning, Lars; Netland, Tim Cato; Hawkins, Anthony D. (Journal article; Peer reviewed, 2019)Recent vegetation changes in arctic-alpine tundra ecosystems may affect several ecosystem processes that regulate microbe and soil functions. Such changes can alter ecosystem carbon (C) cycling with positive feedback to ... -
Marine depth use of sea trout Salmo trutta in fjord areas of Central Norway
Eldøy, Sindre Håvarstein; Davidsen, Jan Grimsrud; Thorstad, Eva Bonsak; Whoriskey, Frederick G.; Aarestrup, Kim; Næsje, Tor; Rønning, Lars; Sjursen, Aslak Darre; Rikardsen, Audun H.; Arnekleiv, Jo Vegar (Journal article; Peer reviewed, 2017)The vertical behaviour of 44 veteran sea trout Salmo trutta (275–580 mm) in different marine fjord habitats (estuary, pelagic, near shore with and without steep cliffs) was documented during May–February by acoustic ... -
Marine habitat use and feeding ecology of introduced anadromous brown trout at the colonization front of the sub-Antarctic Kerguelen archipelago
Davidsen, Jan Grimsrud; Bordeleau, Xavier; Eldøy, Sindre Håvarstein; Whoriskey, Frederick G.; Power, Michael John; Crossin, Glenn T; Buhariwalla, Colin; Gaudin, Philippe (Journal article; Peer reviewed, 2021)In 1954, brown trout were introduced to the Kerguelen archipelago (49°S, 70°E), a pristine, sub-Antarctic environment previously devoid of native freshwater fishes. Trout began spreading rapidly via coastal waters to ... -
