Nat, diff opinion. What size cats do you plan on stocking channels or blues? If larger blue cats they will hammer the bluegill and grow like crazy. Also larger 3 lb channel cats will also eat the bluegill.
If you put in bass they will indeed eat the bluegill and reduce. Dave if it becomes bass crowded, what is the problem? They will help control channel catfish reproduction to help Nat with catfish growth. Or sell the bluegill or use them to fed bass in other pond as suggested. Sorry I see the "pond as half full" not half empty. I would love to have a pond full of bluegill. I could grow the heck out of cats anm a few monster bass that way. Good Luck
