Glen, I think I remember 100 pounds of predators per acre. It's up to you just how you mix it. With 20 five lb catfish, you get no bass. In the equation, you also need to figure that big bluegills are predators. Heck, everything in the pond is really a predator. Also, the fewer predators you have, the bigger they can grow. The point is, if you want a miniature Lake Fork, only put in about 20 predators and keep eating everything under 14 inches after the 2nd or 3rd year.
