Don, my lake is a little over 4 surface acres. The deepest part is about 32-35 feet. Usually bait shops sell shiners. You don't want to stock them in your pond because they will grow to be full size shad. Fathead minnows only grow to about 3-4 inches and spawn 6-7 times a year. Yes, you can use them for crappie fishing as well and crappie LOVE them!!!! Before I stocked the bass, I never bought minnows for bait. I'd go to the lake the evening before going fishing, put out a minnow trap with a half a piece of bread in it. The next morning, the trap would be slap full of minnows!!! Dump about half in a minnow bucket and pour the rest back into the lake.
