Hi MIke well to answer your question about catfish reproduction, I didn't think it was possible but over the weekend I wanted to clean a bunch of my large 3 plus year old catfish out and ran a trotline. Caught 15 cats from 3 to 7 pounds. Also was doing a little bluegill fishing and caught a 8 inch catfish! I don't think there is any way catfish stocked over three years ago only gained at a maximum 4 inches. So I guess last year they did reproduce. I have several hollowed out oak logs courtesy of lovely carpenter ants in my pond and believe these provided the refuge needed. Hope that helps some. Forgot to add my pond is a little over 1/3 acre 8' max depth.
