What I recommend is to rotate lakes for keeping fish on a 4 year cycle where every 4th year you can keep a limit from that specific lake This was tried up by edmonton on hastings lake a number of years ago (20) and after the second or third year the perch were a nice size. Once opened up though one summer/winter cleaned out most of the larger perch but I think my suggestion would work, it seems plausable.
