Crappie are a little tough to predict. They are inconsistent spawners..they don't spawn each year. They spawn before other game fish each spring. Those two facts put a damper on solid fisheries management. Baby crappie eat other baby fish as they come off the nest. Since crappie are predator fish, they are only limited by mouth size. Since they have a big mouth, they can eat big food.
That's why crappie aren't recommended for small waters. It's not a matter of "if" they overpopulate, it's a matter of "when." So, be prepared to monitor your fish population regularly, so you can be prepared to move lots of small crappie when the time comes.
