Welcome to Pond Boss!!!
22 acres is HEAVEN!!!!!
The size of your pond (really a small lake) makes the management of it, towards a desired outcome, more challenging.
You've either got labor/sweat, or money, or a combination of both.
If you got an army of fishermen together in the spring, and tried to remove every Black Crappie you caught, it would probably have some effect towards goals (which need to be defined). I think you'd be looking to try and remove at least (100) Crappie/acre, so over 2,000 fish. Quite an effort.
For muskie stocking, I think you'd want Tiger Muskie as they would not reproduce. At least one per acre would be need to make a dent in the Black Crappie, and probable more like 2-3/acre.
