摘要

Historically, fisheries have been managed as single panmictic units; however, itis more likely that fish species are composed of multiple genetically distinct groups. As a result, management programs should be designed to incorporate this concept of multiple stocks. Although muskellunge (Esox masquinongy) possess morphological and genetic variation among populations, their stock structure remain unknown. Our goal was to investigate the relationship between population genetic structure of muskellunge and geographic distance using a sampling design based on watershed hierarchies. Protein electrophoresis and RFLP analysis of mitochondrial DNA were used to examine populations genetic variation within and among watershed of Minnesota and Wisconsin. Up to 30 individuals from 21 populations (18 populations from Minnesota and Wisconsin and 3 outgroup populations) populations were assessed for variation for four protein loci.
