I think that it would probably be better to use it as a trophy bluegill pond instead of Catfish and Bluegill. From what I figured you would only have about 36 lbs. of fish based on 1000 lbs./acre( I am not sure what the actual numbers are but let's just use this as an example). If you had catfish it wouldn't take long for only a dozen cats to overload the system. You would then have to deal with water quality issues.
