What role to invasive round goby have in the contaminant cycle?


June 2018 - August 2019


Round goby were first introduced into the Great Lakes from the Ponto-Caspian region in the mid 1990s. In the decades that have followed, this invasive species has spread throughout all 5 Great Lakes and is now moving inland through connected waterways. Round goby prey upon invasive Dreissenid mussels, and themselves are prey items taken by most game fish in temperate North America. In this project, we are investigating whether round goby invasions change the mercury fish contaminant cycle. Results from this work will inform fisheries managers about whether fish consumption advisories may need to be updated upon round goby invasions.
