Domestication can have adverse genetic consequences, which may reduce the fitness of individuals once released back into the wild. Many wild Atlantic salmon (Salmo salar L.) populations are threatened by anthropogenic influences and they are supplemented with captively bred fish. The Atlantic salmon is also widely used in selective breeding programs to increase the mean trait values for desired phenotypic traits. We analyzed a genome-wide set of SNPs in three domesticated Atlantic salmon strains and their wild conspecifics to identify loci underlying domestication. The genetic differentiation between domesticated strains and wild populations was low (FST < 0.03), and domesticated strains harbored similar levels of genetic diversity compared to their wild conspecifics. Only a few loci showed footprints of selection, and these loci were located in different linkage groups among the different wild population/hatchery strain comparisons. Simulated scenarios indicated that differentiation in quantitative trait ... : Saint_John_Genotype_dataFile contains SNP genotypes for the River Saint John Atlantic salmon strain and their wild conspecifics.River Burrishoole Genotype_dataFile contains SNP genotype data for River Burrishoole Atlantic salmon strain and their wild conspecifics.Vindel Genotype_dataFile contains SNP genotype data for River Vindel/Ume Atlantic salmon strain and and their wild conspecifics. ...
