Do GSH root in the bottom? My pond water is very brown and I always blamed goldfish first (down to about 30 or less), crayfish second (never can trap a one so there can't be that many), and now maybe the GSH?
One question, you said GSH decimated FHM? I can't see how that works. THe GSH mouth is small even on a 6+ inch size adult. How do they eat FHM?
I have never had turbidity in my 1/10th acre forage pond where the GS are thick, so I would say they do not root in the bottom from my experience.
I stated that poorly about the GS extirpating the FHM. I really don't know for sure what did the FHM in, but I do know the GS population thrived as the FHM population went down. Three things that I can think of likely had to do with the FHM being extirpated. 1. I had several unwanted adult GSF in that pond. Over the last two years I have removed probably 20 in the 5-6" range. 2. Numerous RES breeding size adults in this pond. RES eat FHM. 3. If GS eat fish eggs, I can see where the GS numbers went up and became dense it may have prevented the FHM from having successful broods. Also adult GS likely could eat FHM in the larval or small fry stage. The GS go after the pellets I feed like gangbusters.
