The guides up on the bay of green bay do it all the time, just as long as you are counting those fish eaten as part of your daily bag limit and you keep the skins you should be all right.
It is illegal : (in part)
• to deposit fish carcasses or parts, including entrails or other waste, into Wisconsin waters
or on the bank or shore of any water
• to transport fish subject to a length limit, unless you leave the skin and scales intact (on
the fish); the heads and tails can’t be removed unless the dressed fish or fillets meet the
minimum length limit.
