Hi Bill, I will certainly ask the fishery why they don't want to stock FHM/GSH. But, I'm interested in getting other opinions about their recommendations which is what the forum is all about, right? Are there situations where you can't create a natural food chain? If so, what are they? I can't come up with a good answer.
As for rotenone, I considered this option but there's a stocked pond downstream from mine and we broke the dam on mine for the renovation. If there were an unexpected rain within six days of treating my pond, the water would have run out of my pond and treated his as well. In fact, my pond was draining almost the entire time we worked on it. Even after re-building the dam, there was no guarantee that the new dam wouldn't leak. It just wasn't worth the risk. He was already a little alarmed when my dirt guy broke the dam too fast and his pond level suddenly went up.
Thanks for the comments...
