Ron,
My advice would be to start over and get rid of the crappie. You will never control them in a 3 acre pond. Eventually you will have a pond full of eyeballs and tails. Even if you add bass and catfish the crappie will be hard to control in a 3 acre pond. I have seen the quality of small ponds detroyed by the addition of crappie. As for catching crappie Feb. and March, or whenever they spawn in your area, will be the best time to catch a lot. Sink a bale of hay with cement blocks tied to it in about 4 feet of water. When the crappie start spawning they will gather around the hay. We have caught 250-300 crappie around a bale of hay in one day placed in a large lake.
