Assessing Movements between Freshwater and Saltwater by Brown Trout (Salmo trutta L.) Based on Otolith Microchemistry
Andersson, Magdalena; Jonsson, Bror; Calles, Olle; Greenberg, Larry (Peer reviewed; Journal article, 2024)By analyzing otolith microchemistry, we examined the use of freshwater and marine environments by brown trout Salmo trutta L. that spawn in the Swedish River Emån and migrate to the Baltic Sea. We estimated the time juveniles ... -

Upstream fishway performance by Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) spawners at complex hydropower dams – is prior experience a success criterion?
Hagelin, Anna; Museth, Jon; Greenberg, Larry; Kraabøl, Morten; Calles, Olle; Bergman, Eva (Peer reviewed; Journal article, 2020)Passage of hydropower plants by upstream-migrating salmonid spawners is associated with reduced migration success, and the need for knowledge of fish behavior downstream of dams is widely recognized. In this study, we ...
