Population genomic analyses of early‐phase Atlantic Salmon ( Salmo salar) domestication/captive breeding
Abstract Domestication can have adverse genetic consequences, which may reduce the fitness of individuals once released back into the wild. Many wild A tlantic salmon ( S almo salar L .) populations are threatened by anthropogenic influences, and they are supplemented with captively bred fish. The A...
