Gator - I tend to agree with Greg's last post of Nov 01. One thought about the local biologist's liming comments. I would double check with him about what the stocking densities (or the fish densities) were in the ponds he is referring to where you will not need lime. Does he know how many fish you are planning on putting in the test pond and that you are feeding on a daily basis?. Make sure he is not assuming you will be stocking a low or normal densitiy and not going to feed the fish. It is fine to follow his advice if you use his recomendations for stocking density. Make sure he understands the details of what you are planning on doing so you are both on "the same page" for goals of this project.
