When discussing the introduction of aquatic invasive species many people are aware of species that are introduced by the movement of ballast or bilge water from barges to recreational kayaks.

There have been several regional campaigns to discuss this issue and the changes in the legislation to prevent the introduction, transportation and sale of these potentially harmful species. Below is a chart that we think would be useful to anglers and provide some awareness to which species are harmful to use in Michigan or Wisconsin.
