Numbers of fish should be determined by a number of things.
First, your goals. Well defined goals help with decisions about how many of each fish.
Second, your timeline. Want to stock fingerlings, let them grow up and wait two years to catch fish? Or, want to catch fish next week?
Third, build the food chain, first. So, if you want largemouth bass, you'll want to start a new pond with fathead minnows, bluegills, maybe some pumpkinseeds and redear (if they'll live in NE Ohio). Give these fish some time, then stock bass.
As far as numbers go, if your goals are basic, I'd stock 10 pounds of fathead minnows, 500 bluegills (not hybrid sunfish), pumpkinseeds and redear sunfish if you can get them, 100-150 each of those, and follow at least six months, up to a year, with 50 bass fingerlings.
