AB - We used allozymes and mitochondrial DNA (mtDNA) restriction fragment length polymorphisms to determine if spawning populations of walleyes Stizostedion vitreum from the Lake Erie–Lake Huron corridor are genetically differentiated and to estimate their contributions to a commercial fishery in southern Lake Huron (operated by Purdy Fisheries) in 1994 and 1995. Both types of genetic markers detected significant differentiation among walleyes collected from different sites, suggesting that fish from Lake Erie, Lake St. Clair, and Lake Huron are not a single, genetically homogeneous population. The combined use of both marker systems detected the greatest differentiation in pairwise comparisons of samples. Although some exceptions were detected, both marker types suggest a relationship between geographic proximity and genetic differentiation. The fish from Purdy Fisheries caught throughout 1994 had highly significantly different haplotype frequencies (mtDNA) but not allele frequencies (allozymes) from those caught throughout 1995. The estimated contributions of walleyes from different spawning sites to the catch from Purdy Fisheries varied little between years. Most estimates were significantly greater than zero, indicating that all sites contributed at some level and none should be ignored in management considerations. The mixed‐stock analysis was robust when factors affecting bias and precision were evaluated.
