Impact of stocked Atlantic salmon (Salmo salar L.) on habitat use by the wild population
We investigated the summer habitat occupied by populations of young-of-the-year wild and stocked (farmed populations released into the native range) Atlantic salmon under allopatric and sympatric conditions. Under allopatric conditions, farmed and wild salmon occupied habitats with the same characte...
