Probably didn't have a fishing license either. This little lake (5 acres) that I fish has some nice size Bluegill in it but because of the size of it the limit is 10 fish total with only 1 LMB of 18". This guy had a whole stringer of bluegill. I mentioned to him that the limit was 10, he says yea but I have never seen a Conservation Agent up here, have you? I replied yeas he was here yesterday, really nice guy. The guy fished about another 10 minutes and left. I think the had 12 BG but I believe if I hadn't said something he would have kept fishing. I haven't seen him fishing there since.
I have the contact information for the conservation agents in my area in my phone, just for cases like that. I also have the number for the Missouri's Operation Game Thief 1-800-392-1111 you can call them from any place in the state and they will find someone to respond. The number is answered 24/7
