Spatial distribution of migratory Salmo trutta in the northern Baltic Sea
Spatial distribution of brown trout (Salmo trutta) was studied on the Finnish coast of the northern Baltic Sea in 1998–2010 based on smolt tagging. The studied trout stocks were hatchery reared, and smolts were tagged with Carlin tags before release into the rivers. The distance between the release...
