Stake beds sure wouldn't hurt. Depending on the size of the pond, you'll need predator fish aka large mouth bass to help keep the crappie from over populating. Black crappie are a little less apt to over populate but it can still happen. Also keep a good supply of bait fish for forage like fat head minnows and grass and brush growing in the edge of the water will help give small fish hididng places and crappie ambush cover. Good Luck
