I also have a concern regarding your stocking. First, you should stock a max of 100 bass per acre.
Also, what will they eat? The hybrids are, at least theoretically, sterile. You should have stocked plain bluegills. They are breeding machines. You should also have stocked them a considerable time before the bass so they could grow to breeding size, reproduce at least once and become well established before adding predators.
The 'generally used' recipe for stocking is 5 lbs of fatheads per acre, 1000 bluegills (500 bluegills in some circles) per acre and 100 predators per acre. The predators are usually LMB or catfish but are sometimes big bluegills. Now, this is for initial stocking. Your own goals will determine the mix that you will cull to and try to maintain.
The fish farm jerked you around. Read the posts here about stocking rates and getting established.
