With some of the best ice up north, the Wisconsin DNR is asking fishers to help prevent the spread of aquatic invasive species.
Even in harsh winter conditions, anglers can transport aquatic invasive species and fish diseases from one lake or river to another by emptying water from bait buckets and fish containers.
The diseases come from lake and river water bait buckets that are drained.
The DNR says state regulations allow up to two gallons of water to transport minnows if no lake or river water has been added.
Fishers are also reminded to never dispose of unwanted bait in a lake or river.
Lastly, before leaving your fishing spots, the DNR says to remove any mud or plant material clinging to gear, including sleds used to haul supplies.
Some invasive aquatic plants, like curly-leaf pondweed and Eurasian watermilfoil, flourish under the ice.
