Abstract

To persist in the face of climate change and human activities, organisms may need to adapt. We showed that Atlantic salmon from River Teno (between Finland & Norway) evolved over the last 40 years to mature earlier. Our data suggest it was due to indirect and direct effects of fishing: harvesting of capelin to feed farmed animals, and size selective net fishing in the river.
