A few fishermen have inquired recently about the legality of taking fish in both Ohio and Michigan on the same day, and keeping in line with the rules on both sides of the border. The simplest answer is: pick one state, fish it all day, then start fresh someplace else the next day. But some anglers expect to bounce back and forth, and they want to stay clear of trouble. A couple of basic rules for border-hopping fishermen: 1. if you reside in Ohio, you may leave from the Ohio shore, take a limit in Ohio, and return to Ohio's shore. You may not then leave from the Ohio shore, travel to Michigan waters, take a limit, and return again to Ohio waters in the same day. That would put you over the possession limit for the day in Ohio. 2. you may leave from Ohio shore, fish Michigan waters and return to Ohio water with walleye caught in Michigan, but you may not be in possession of more than the allowed daily limit of walleye in Ohio. Obviously, make sure you are licensed in both places, and fishermen need to be very aware of the daily possession limits in both states -- that's where you can get yourself into trouble.
