The muskellunge (Esox masquinongy) is an important recreational fish species native to the northern and eastern United States. The species has a long history of stocking and hatchery propagation. In order for the best management practices to be implemented, the genetic variation and structure within and among stocks must be understood. Currently, muskellunge are classified into three subspecies corresponding to major drainages, but these designations are disputed. In this study, the genetic stock structure of muskellunge was investigated at two scales: at the species level and at the local population level for Ohio’s muskellunge stock. Using mitochondrial DNA (mtDNA) sequence variation, I examined the range-wide intraspecific phylogeographic patterns of muskellunge. Using three nuclear microsatellite loci, I assessed local stock structure of hatchery and natural populations in Ohio. Very little mtDNA sequence variation and a lack of genetic structure among populations from throughout the range do not support the subspecies designations. Further, the widespread distribution of two similar haplotypes suggests recent dispersal from a single glacial refugium. High levels of microsatellite variation within and between Ohio populations identified significant stock structuring among populations. Recent bottleneck events do not appear to have reduced genetic diversity in the sampled populations. Based on my data, Ohio contains at least five genetic stocks that should be maintained as separate management units.
