Zebra mussels are an invasive species that represent a significant threat to rivers and lakes because they multiply rapidly and attach themselves to native mussels, killing them and altering ecology and food chains. Their hard shells also cut swimmers’ feet and fishing lines and inundate docks. Found now throughout the Great Lakes and Mississippi River regions, they have rapidly spread to several state lakes in recent years, their microscopic larvae transported in bait buckets and bilges.

Although there are chemical treatments to control zebra mussel infestations, these require very careful application and often involve permits. Boaters, anglers, and waterfowl hunters can help prevent further spread of zebra mussels by inspecting, cleaning and drying boats, equipment, and tackle. Be sure to drain water from live wells, bilges, and bait buckets. Do not transport water from one body of water to another.
