Nope. Needs to be on hook and line. Otherwise, I would be grabbing walleye all year long (easily done by grabbing just in front of the caudal using a good pair of gloves). Grabbing (and keeping) a musky is more challenging - I've never been able to keep one - due to their slimy/smooth exterior.
But here's the 'loophole'... The DNR states that the fish must be taken by hook and line, but says nothing about where the fisherman must be. Up north at Sand Lake, we continually tried to catch the big crappie and bass that live underneath the fish cribs. But the stupid little rock bass (which live above the cribs) would continually strike our bait before it could reach the big fish. So I shedded my duds, tied a 3-foot piece of 20 lb test to a nylon lanyard, baited my hook, and dove to the bottom of the cribs. I threw the bait under the cribs and waited for a strike. Pulled out many nice fish that day, while my buddy landed only runts. The activity started to draw the attention of local fisherman, until finally, someone ratted me out to the fuzz. When the warden pulled up [his boat] to see what I was doing, he had to bust out the thick book of laws and make a few calls on his radio..... but in the end, no problems.
