Controlling smaller fish with larger fish isn't as hard as this thread suggests. It also shouldn't take more management time than an excellent LBM environment. The A-B-C's book on successfully raising Large Black Crappie is in the 2nd year of fact gathering. I only have a few pages so far, but I'm documenting what I hope to be a cookie-cutter model. The body includes stocking numbers, forage base sampling, growth expectations, and predator controls. I realize every pond is different, but the controlling factors to limit overpopulation should be similar. At the end of the first 2 year cycle in August, I will post it as "work in progress".
