Twelve microsatellite loci for lake trout (Salvelinus namaycush)

We describe 12 microsatellite loci isolated from lake trout (Salvelinus namaycush). The number of alleles at these loci ranged from two to 11 with an average of 5.3 alleles per locus. The expected heterozygosity ranged from 0.29 to 0.76, with an average of 0.68. Accidental (or illegal) introductions of lake trout into watersheds are decimating native trout populations in the northern Rocky Mountains, and these loci will be useful for identifying the source of these introductions and for estimating the number of founding individuals.
