Genetic Similarity among Endemic Arctic Char ( Salvelinus alpinus ) and Implications for Their Management
Five isolated populations of landlocked Arctic char (Salvelinus alpinus) from eastern United States and Canada were compared electrophoretically with anadromous Arctic char from the Northwest Territories. Mean heterozygosity was relatively low (0.03) with allelic variation observed at 7 of the 26 is...
