Aquatic invasive species can move between basins through the places where our waterways connect.
The sale of fish, plants and other organisms can cause the spread of non-native species into the Great Lakes.
Ballast water is one way invasive species hitch a ride to new habitats.
Recreational boaters may unintentionally transport invasive species on power boats, jet skis, and other watercraft.
