Here in Wisconsin the DNR appreciates phone tips we have had some major busts from other fishermen taking pictures and contacting the DNR while still on the water. Here the DNR tries to get there as soon as they can to take advantage of a tip take a pic of there boat number for more follow up, a few times DNR has contacted the local police to help out. Here we take over limit very seriously if possible. Ice fishing is the hardest as usually they are in a shack so no one can see what is going on.
