Round gobies
     are native to the Black
  and Caspian Sea regions in
    Europe/Asia. They were
introduced into the Great Lakes
   through ballast water from
trans-continental ships. In 1990,
round gobies were discovered
 in the St. Clair River and have
    quickly spread into all of

          the Great Lakes.

              Round gobies                 What is being done to stop the
        are found in all of the          spread of round gobies and other
  Great Lakes, attached tributaries
   up to the first impassable dam,         aquatic invasive species (AIS)?
and some inland waters in the United
  States. The U.S. Geological survey      While the DNR is working to prevent the spread
keeps an updated interactive map of       of invasive species on several fronts, their efforts
 verified round goby findings that        often fly under the public’s radar. Here are just a
  can be accessed online. Round           few examples of what the DNR is doing to combat
    gobies are currently in only one       round gobies:
    inland lake in Wisconsin; Little
         Lake Butte des Morts.         NR40 regulations and laws make it illegal to
                                           possess, transport, transfer, or introduce any
                                           invasive species in the state of Wisconsin

                                       Signage has been posted throughout the system.

                                       Round goby watch cards are distributed to anglers,
                                           boaters, and at outreach events.

                                       There is also a DNR online reporting tool and phone
                                           number (920-424-3050) that the public can use to
                                           report a suspected round goby if one is caught.

                                       As round gobies can be introduced through disposal
                                           of unused bait, the DNR has been working on a
                                           statewide bait shop outreach initiative to bring
                                           educational materials to those selling and
                                           purchasing live bait.

                                       Working directly with anglers and boaters through
                                           the Clean Boats, Clean Waters program to further
                                           round goby (as well as other AIS) awareness and
                                           assisting with monitoring efforts for gobies.
