ewest, I will follow through with your suggestions on the F1's. These fish may only be 1 to 2 inches. I don't know much about tagging or fin clipping but I assume it might be pretty difficult with fish this small, although I would love to have some sort of identification to tell the difference between strains. I am up for suggestions on that, but maybe that should be on a different thread. NightRider, I am in SE Illinois, East of Mt. Vernon. Thanks again guys.
