ill leave most of the numbers to the experts but you wont be able to have alot of catfish in their maybe tops 25 to 35 with feed. As your bluegill and RE and HBG im guessing not many of them either, probably about 100 total split up however u want. Also make sure u get about 3-5 lbs of fatheads in there soon.
But the problem with this type of pond is that it can and probably will over populate with bluegill unless you seine it or trap it.
Another option is to have a channel catfish only pond with fatheads and supplemental feeding. These types of ponds are probably the easiest to maintain. If u decide to go with this type of pond you will need up to about 8 - 10lbs of fatheads and can possibly increase your catfish numbers by ten or fifteen more also.
The reason you'll be able to hold more cats is that there won't be any competition for the feed from any of your BG, RE, and HBG.
But thats just a thought
