A Genetic Based Approach to Management and Stocking of Muskellunge
No full textFish stocking has long been used as a management tool among fisheries biologists and continues to be met with popular public opinion. Despite perceived simplicity, the full effects of stocking remain cryptic for many fish populations. Stocking has frequently been used to maintain or establish successful muskellunge (Esox masquinongy) populations. Coupled with other management practices the Minnesota Department of Natural Resources (MNDNR) has established Minnesota as a premier muskellunge fishery. From 1958 to 2012 the MNDNR stocked three strains of muskellunge in Big Mantrap Lake, MN. The first from Shoepack Lake, MN (hereafter Shoepack-strain) was used until the realization that fish were not attaining sizes sought after by anglers. The MNDNR then made a statewide switch to a source from Wisconsin before developing a source from Leech Lake, MN (hereafter Leech-strain). Using 13 microsatellite markers, genetic contributions of each source population were estimated from samples taken between 1984 and 2013 in Big Mantrap Lake. Analysis of current and past genetic makeup of Big Mantrap Lake demonstrated a successful dilution of the Shoepack-strain from 96% in 1984 to 11% in 2013 as the Leech-strain made up 85% of the genetic makeup in the most recent sample. This study reinforces the use of genetic information as a management tool in evaluating ancestry of stocked fish. These findings will help the MNDNR make management decisions related to size structure and genetic makeup of muskellunge populations

Assessing the Contributions of Two Stocked Strains on a Minnesota-Wisconsin Border Water
No full textStocking has long been used as a management tool in the United States even though many of its effects remain cryptic. Past comparisons between stocked strains were generally based on the survival and growth rates of physically marked individuals. More recently the use of genetic markers to assess contributions of stocked individuals has been employed by fisheries managers. Using 13 microsatellite markers we assessed the contributions of two muskellunge (Esox masquinongy) strains (Wisconsin and Leech) stocked into the St. Louis River Estuary. Ancestry in the adult samples remained relatively constant with differences only observed between the 2008 and 2013 samples. Samples for young of year individuals told a different story with no significant differences observed between any sample years. Due to these differences more information from additional sample years will be needed to determine if we are really witnessing a change in the genetics of fish in the system. Regardless, both strains appear to be contributing to a healthy muskellunge population; the St. Louis River Estuary shows us one of the benefits of interstate management
