Aquatic invasive species thrives in winter
From Michigan State University Extension-
When winter freezes Michigan inland lakes, the threat of the spread of aquatic invasive species (AIS) does not go away. Boats were drawn out of the water, cleaned and stored for winter. Docks that could be pulled ashore were, but then out comes the ice fishing gear. Shanties are slid onto the ice, holes are augured and a new season of sport begins and with it the spread of AIS.
