Even though release strategies have been improved, recapture rates of hatchery-reared Atlantic salmon as adults have been low in the River Eira, Norway. To evaluate whether loss of fish occurs in the river immediately after release, in the early marine phase in the fjord, or during the subsequent feeding migration at sea, 20 smolts were equipped with acoustic transmitters. The survival and movement pattern of the smolts were monitored along the 9-km-long river and during the first 37 km of the… CONTINUE READING
