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 ... -
Environmental influences on life history strategies in partially anadromous brown trout (Salmo trutta, Salmonidae)
Nevoux, Marie; Finstad, Bengt; Davidsen, Jan Grimsrud; Finlay, Ross; Josset, Quentin; Poole, Rusell; Höjesjö, Johan; Aarestrup, Kim; Persson, Lo; Tolvanen, Oula; Jonsson, Bror (Journal article; Peer reviewed, 2019)This paper reviews the life history of brown trout and factors influencing decisions to migrate. Decisions that maximize fitness appear dependent on size at age. In partly anadromous populations, individuals that attain ... -
Life-history strategies in salmonids: the role of physiology and its consequences
Birnie-Gauvin, Kim; Bordeleau, Xavier; Cooke, Steven J.; Davidsen, Jan Grimsrud; Eldøy, Sindre Håvarstein; Eliason, Erika; Moore, Andy; Aarestrup, Kim (Peer reviewed; Journal article, 2021)Salmonids are some of the most widely studied species of fish worldwide. They span freshwater rivers and lakes to fjords and oceans; they include short- and long-distance anadromous migrants, as well as partially migratory ... -
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 ... -
One Hundred Pressing Questions on the Future of Global Fish Migration Science, Conservation, and Policy
Lennox, Robert J.; Paukert, Craig P.; Aarestrup, Kim; Auger-Méthé, Marie; Baumgartner, Lee; Birnie-Gauvin, Kim; Bøe, Kristin; Brink, Kerry; Brownscombe, Jacob W.; Chen, Yushun; Davidsen, Jan Grimsrud; Eliason, Erika J.; Filous, Alexander; Gillanders, Bronwyn M.; Helland, Ingeborg Palm; Horodysky, Andrij Z.; Januchowski-Hartley, Stephanie R.; Lowerre-Barbieri, Susan K.; Lucas, Martyn C.; Martins, Eduardo G.; Murchie, Karen J.; Pompeu, Paulo S.; Power, Michael; Raghavan, Rajeev; Rahel, Frank J.; Secor, David; Thiem, Jason D.; Thorstad, Eva Bonsak; Ueda, Hiroshi; Whoriskey, Frederick G.; Cooke, Steven J. (Journal article; Peer reviewed, 2019)Migration is a widespread but highly diverse component of many animal life histories. Fish migrate throughout the world’s oceans, within lakes and rivers, and between the two realms, transporting matter, energy, and other ... -
Redefining the oceanic distribution of Atlantic salmon
Rikardsen, Audun H.; Righton, David; Strøm, John Fredrik; Thorstad, Eva Bonsak; Gargan, Patrick G.; Sheehan, Timothy F.; Økland, Finn; Chittenden, Cedar; Hedger, Richard David; Næsje, Tor; Renkawitz, Mark; Sturlaugsson, Johannes; Caballero, Pablo; Baktoft, Henrik; Davidsen, Jan Grimsrud; Halttunen, Elina; Wright, Serena; Finstad, Bengt; Aarestrup, Kim (Peer reviewed; Journal article, 2021)Determining the mechanisms driving range-wide reductions in Atlantic salmon marine survival is hindered by an insufcient understanding of their oceanic ecology and distribution. We attached 204 pop-up satellite archival ...
