I recently bought a house on the lake and have been fishing it only for the past year or so. It seems like an odd fishery to me. From what I've seen on the electronics and from what I've caught, Redstone seems to have a healthy forage base, and a ton of Crappies that move around. There are some carp, bass, walleye, northern, perch, bluegil, muskie, and catfish, but I haven't found any consistent patterns to them. It looks almost random where I've caught them. Also looks like the lake gets a lot of fishing pressure, and a lot of fish are taken out. I'd love to see the results of the latest survey they are doing to see what kind of numbers and sizes they get.
I agree, introducing a new predator is probably a bad idea.
