Canyoncreek there are always trade offs. The KOI and Israeli carp are mostly for algae control and they did a really good job on the FA. There was some turbidity, but some of it was pea green bloom, which is good. So how much was bloom and turbidity is hard to tell. The KOI and Israeli carp grew to be huge but I never had any more then what I stocked in the pond over the years and that has to be because the bass controlled them.
I think the grass carp could eat all the Eurasian Milf-oil if the numbers were close to mine at 18 per acre. My milfoil was so thick that I built a raft so I could put piles of milfoil on it while I was in the water to hull to shore. I finally give up harvesting as a waist of time. The trade off with the grass carp was they pretty well cleaned out the pond of submerged plants. Trying to get rid of too many grass carp was not working for me. I tried to spear some and that didn't work.
