River Eira once harbored some of the largest salmon in the world, but has now evolved into an ordinary salmon population. New study shows clear evidence of an unintentional human-induced evolution.

While it is known that the oceans around the Faroe Islands support an Atlantic salmon feeding ground, the relative use of this resource by different age classes and populations has, until now, been largely unexplored.

New study of adult Atlantic salmon in near-coastal areas shows that they migrate through surface waters and perform aperiodic dives - both on outward migration and return.
