Round gobies entered the St. Clair River in 1990 likely through ballast water from ocean-going ships. Some people have tried to get rid of this species and have failed in the past leaving the invasive species still living at the Great Lakes. "The Round Goby", 2011. The Round Goby is recognized as one of the top 100 invasive species globally (Johansson and others, 2018).
