Aquatic invasive species (AIS)

Sea lamprey

The Great Lakes have experienced ecological changes brought about by aquatic invasive species such as sea lampreys, alewives, zebra mussels, round gobies, ruffe and white perch. Wisconsin Sea Grant is a leader in research and outreach related to these aquatic nuisance species. Current efforts focus on educating the public about quagga mussels and other invasive species, developing ways to control their spread, reducing their adverse effects, and combining conceptual and analytical tools required to evaluate fishery restoration efforts.
