Evidence of temporal genetic change in wild Atlantic salmon, Salmo salar L., populations affected by farm escapees
Abstract A large number of farmed Atlantic salmon escape from sea cages and hatcheries annually. Selection programmes and domestication have changed the genetic composition of farmed salmon to improve their performance in the culture environment, which apparently occurs at the cost of their fitness...
