i have put a total of 500 bass in my 4 1/2 acre pond,before adding these 100 bass there were 400 bass in the pond.they were put in the pond about 6 months after bream and minnows.the reason i added another 100 bass is because bass fishing is not very good.now would you think these 100 4-6 inch bass would surive?this pond is all most 3 years old.the few bass we do catch are about 10% heavier than bob's book says they should be,just don't catch many.thanks
