ABSTRACT. The round goby (Neogobius melanostomus) is an invasive fish species originating from the Black and Caspian Seas that has significantly impacted the ecology and economics of the Great Lakes region. Improving monitoring methods of the round goby will help in creating more efficient, cost-effective strategies for managing this invasive species. Recently, high-throughput sequencing of environmental DNA (eDNA) has been used to increase detection capabilities of fish species in aquatic systems. Metabarcoding approaches such as these allow for effective relative assessments of the abundances of individual species within a community, and thus are well suited for monitoring invasives. Here we use metabarcoding of eDNA to monitor invasive round goby populations in Lake Michigan. Our study focuses on a newly installed artificial reef at Jeorse Park (East Chicago, IN), examining the influence of these structures in supporting native fish populations over those of the round goby. Water samples for our study were collected at five onshore and offshore locations near the reef at Jeorse Park over the course of the 2018 summer season. In order to validate our methods in freshwater, we also took samples during traditional field monitoring expeditions as well as from indoor freshwater tanks with known communities of fish that are native to the Great Lakes. All samples will be sequenced this fall for analysis using the previously described MiFish/MitoFish bioinformatic pipeline.
