I have about 3 inches of visibility in my pond, there is probably enought suspended clay to model GM's protoypes for the next ten years. I am in dire need of a predator and would like to know what role, if any, the turbidity plays in the numbers stocked. I have abundant forage, tilapia, and I feed once a day. I have a poacher and at least one small heron, they will account for about 40% mortality based on past experience. The predators are 1 3/4", can't find larger, thats a Theo logical story.
