Evidence of freshwater feeding by adult salmon in the Tana River, northern Norway

In the River Laksjohka, a tributary of the Tana River (northern Norway), stomachs from 45 out of 133 adult Atlantic salmon Salmo salar contained food items of terrestrial and freshwater origin. In the neighbouring River Maskejohka, none of 18 sampled stomachs contained any food items. (C) 2001 The Fisheries Society of the British Isles.
