I have went back and removed all the dead BG from the pond that I can see. None of them look like they are diseased. I could tell that some had been there longer than others, two were still alive but barely. The water in the pond is getting too clear the bloom is fading away. I can see about 4 ft into the water at the banks. I also made a attractor out of pvc pipe a placed it about 6-8' from the bank and I can see the lower legs thought the water. I also cut opened one the BG that was still alive and I didnt notice much in the way of fat tissue (orange colored mass), but than I am not much of an expert on fish tissue. Still looking for more help and advice. Thanks
