I have had this happen to me quite often with silvers. Once a game warden watch it happen, I asked him if I could keep it? he said "I wont fault you for that you hooked it legit." Alot of these silvers roll and when your using a barbless jig the hook comes out alot when the fish rolls. Of course if your dragging a fish up on the bank by the arse as the warden appears youll have one heck of a time explaining yourself! Kinda like when a fish hook legit in open waters runs to closed waters.
