I'm thinking about maybe stocking hybrid species, to avoid over population, while providing the best fishing experience for the grand-kids. Not really critical. The pond will end up being just under 1 acre of surface area, with a maximum depth of about 14', several areas of 2' to 4' for spawning bed and some man-made coverage. So, I'm not "locked" into any plan right now, and am certainly open to suggestions. Your enviornment and mine are probably pretty close to being alike.
