Zebra Mussel - Note Adult Size and Strips on Shell  Zebra Mussel

There have been reports of people cleaning up zebra mussels on their beach and then taking them to other areas (other people’s property) and dumping them.

We contacted Mark Ranweiler, Regional AIS Specialist for our region of the state.  His response:  “It is illegal to transport without a proper permit and they should be disposed of properly and not on someone else’s private property.” Below is a web link to the permit to be used in the transport of invasive species as supplied by Mark Ranweiler.
