The difference with Erie is that there is a commercial catch on Erie and there is no such thing on the Inland Lakes. Erie is managed so all of the States that border her and Canada can take fish in the amounts that is deemed safe to maintain a viable population by leaving enough brood stock to replace the fish that are taken either commercially or by sportfishing. It would or could be quite possible there would be no limit on perch in Erie if there was no commercial fishing, but that is only my opinion and I am not advocating commercial fishing should be or should not be allowed.
