I agree with advice here but one word of caution to throw in the mix. If you really like crappie add a few (~30) now along with other predator after the minnows, bluegill are established. I have had a hard time getting crappie started in a pond with good bass populaiton so start now but DO NOT let them overpopulate. This is a tough task on 1 acre pond but go for it. Take others advice add another predator or you will be sorry with carppie growth without numbers being controlled.
