What Do Round Gobies Mean for Great Lake Streams?

The round goby has dramatically altered Great Lake food webs since it was first discovered in Lake St. Clair in 1990. But the aggressive invasive has spread beyond the blue borders of our Great Lakes. What might gobies mean for the tributaries and streams they are now colonizing? The UW Sea Grant Institute put together this video of the CFL’s Jake Vander Zanden and his (then) grad student, Matt Kornis, as they set out to answer that question.

  1. As a professional bass fishing guide, invasive species are always a concern for me. In my geographical area the invasions are more along the lines of invasive weeds, but we still have to cope with some waters where people have released exotic species of fish and they end up becoming a problem to deal with.
    The Great Lakes seem to be a hot bed of this and show the effects on a larger scale, simply because of the sheer size of the body of water and the number of foreign vessels that operate in them. Thanks for the info you posted here on the Goby.
    I do hope invasive species are brought under control somehow.
