RatherB...stocking seems a simple project. But, things get a little cloudy sometimes, depending on your goals. Here's standard stocking rates. Stock 5 to 10 pounds of fathead minnows per surface acre. In Texas, stock 750-800 bluegill per acre, with 200-250 redear sunfish per acre. If you want catfish, stock up to 100 per acre, unless you want more. But, the more catfish you stock, the more you will need to harvest. Actually, true catfish aficionados may stock as many as 1,000 per acre, as long as they are harvesting when fish reach a pound to pound and a half. So, I usually tell people to stock as many catfish as they actually think they will use over two or three years. Stock a few, add some later, restock as harvest progresses. Look at channel catfish as a "put and take" species. After forage fish have been in place for a season, then stock bass fingerlings at the rate of 50-75 per surface acre.
And, I always try to dissuade people from stocking crappie. Crappie overpopulate small waters.
Now, if I were you, I would stock more bluegill now, then add 50 bass fingerlings per acre when available next spring. As crappie reach catchable size, remove them. Focus on bass growth. They will be your top line predator, the fish which adjusts numbers of other species.
