Some of Wisconsin’s worst aquatic invasive species (AIS), such as zebra mussel larvae or spiny water fleas, can be spread from lake to lake through transported water. That’s why the Department of Natural Resources (DNR) recommends draining boats and livewells before moving from lake to lake.
For proper boat care, make sure that all algae and plants are off your boat and that all of your boat’s plugs have been drained. The DNR recommends allowing your boat to dry for five days or to spray a simple disinfectant mixture (2.5 tablespoons of bleach mixed with 1 gallon of water) to clean your boat.
In addition to proper boat care, the DNR urges boaters and anglers to leave all plant and live animal life at the lake that it was found and to dispose of unwanted bait in the trash. When bringing fish home, the DNR recommends keeping the fish on ice instead of in a bucket of water.
