Like zebra mussels, it spread across Europe, reaching the Baltic Sea in 1992 and the United Kingdom in 2004. It was first reported in the Great Lakes by NOAA in samples Read more about Bloody-Red Shrimp[…]
Where did the golden mussel come from? The golden mussel is native to China and Southeast Asia. It probably made its way into South America via ballast water. Although it has not been detected in North America, it is predicted to be a future threat. Why is the golden mussel a problem? When the Read more about Golden mussel[…]

Coastal shore protection structures Explore Great Lakes processes on shorelines through this fact sheet from Sea Grant’s coastal engineering specialist. He then offers thoughts on structures that interact in the best possible ways with those natural processes. Construction setbacks Selection of a setback distance from a coastal bluff or bank is one of the most important decisions Read more about Coastal solutions[…]
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 Read more about Aquatic invasive species (AIS)[…]

An environmental food web is an intricate, organic and delicate thing. Eliminate a strand here or introduce a new one there, and the entire structure can collapse. That’s why researchers have paid such close attention to the food webs in Lake Michigan, where the appearance of several aquatic invasive species has threatened to upset the Read more about How Many Sport Fish Can Lake Michigan Support?[…]
Summer is a perfect time for Wisconsin boaters to think about responsible boating practices. Simple actions help prevent the spread of aquatic invasive species. The Clean Boats, Clean Waters program educates boaters about those steps.
A collaborative research project about the impacts of quagga mussels in Lake Michigan has led to more than $1 million in funding for the issue from the National Science Foundation (NSF).
Wisconsin Sea Grant’s Titus Seilheimer spent last summer testing the effectiveness of hot water to kill invasive species in recreational boats.
