    • New York State Department of Environmental Conservation.

    • The New York State Department of Environmental Conservation (DEC) and the New York State Canal Corporation continue to implement a comprehensive effort, including a rapid response plan [PDF, 1.73 MB], to combat the potential spread of the round goby, an aquatic invasive species (AIS), to the Lake Champlain Basin following the discovery of the fish in the Hudson River near the city of Troy in July 2021. Aquatic invasive species can out-compete native fish species, disrupting ecosystems and damaging local economies dependent on recreation.

  • MDC Asks Anglers to Help Stop Invasive Round Gobies

    • Missouri Department of Conservation.

    • Missouri Department of Conservation (MDC) fisheries biologists say that the Show-Me-State has another aquatic invader to be on the watch for. It's already been detected in the Mississippi River near St. Louis—and anglers might be the first line of defense. The round goby (Neogobius melanostomus) is native to the Black and Caspian Seas between Europe and Asia and was brought to the U.S. by way of the Great Lakes in cargo ship ballast. Since then, the invasive fish has made its way down the Illinois River and has been confirmed just across the Mississippi at Alton, Illinois. MDC encourages anglers to take photos and email MDC with details if they encounter any round gobies. Anglers should report the sighting and email photos to
