The pros will be along shortly with good advice. I think Crappie tend to overpopulate and stunt unless in large bodies of water. Your initial stockers may grow well but in very few years you won't have any of much size. Your BG numbers look fine to me. Are you going to feed them? If so, you could probably up those numbers some or just wait a couple years and you'll have a lot more naturally. Largemouth bass can be tricky. They can overpopulate and stunt too. It totally depends on what you want. If you want to catch a lot of 10 to 12 inch bass, you can stock more than of you want to catch some 4 or 6 pound bass. I think the rule of thumb is a pond can support about 100 lb. of LMB per acre. That would be 50 2lb bass or 20 5lb bass. However, you will need some predator to hopefully keep your bluegill numbers in check. Largemouth bass will do that okay. It is hard to keep the predator/prey ratio in balance over time.
