Diel migration pattern of Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) smolts : an assessment of environmental cues
Haraldstad, Tormod; Kroglund, Frode; Kristensen, Torstein; Jonsson, Bror; Haugen, Thrond O. (Journal article; Peer reviewed, 2016)The timing of smolt migration is a key phenological trait with profound implications for individual survival during both river descent and the subsequent sea sojourn of anadromous fish. We studied relationships between the ... -
