| Abstract: | Feeding activity of migrating wild Atlantic salmon smolts was investigated in different types of tributaries of the River Teno, northernmost Finland. General feeding activity and the amount of surface prey in the stomachs were correlated inversely with proportion of habitats with high water velocity in the tributaries. |
