Just banging around the DNR site I see you can bait shrimp or not bait. I’ve never heard of baiting shrimp.
The non-resident license to bait in Sept.is $500! I can buy a lot of shrimp for $500 bucks.
On the other hand ‘without bait would only cost me $35. And the season looks like it starts in May.
I'm not clear on limit May-Dec on a boat though.
