If your goal is to have catfish, those numbers are okay. But, they will need to be fed and you will need to harvest them when they get to 2 pounds, probably in the third year.
Bluegill numbers are probably okay.
The biggest issue you will have to deal with is the huge sizes blue cat become. Once your blue cat grow beyond 20 pounds, they become the dominant fish in the system. As predators, they will pretty much eradicate the other fish...at least those which fit into their mouths, especially sunfish.
If that's your goal...
