Reduced Genetic Variability in First-Generation Hatchery Populations of Atlantic Salmon ( Salmo salar)
Levels of genetic variation were measured in first-generation Atlantic salmon (Salmo salar) cultured for stock enhancement programs in eastern Canada and compared with variation in wild stocks. One regulatory and 19 structural protein loci were screened of which 10 were polymorphic. Mean heterozygos...
