anth, I've never used rotenone, but I think I wouldn't want to use it in any capacity in any BOW where there was fish I wanted to keep.
I think the greatest fear of introducing gizzard shad is infestation beyond control. I may be experiencing that same issue with intentional golden shiner stockings where numerous predators were present in a very captive situation.
I want to say Greg Grimes had trophy bass plans that included gizzard shad, so you could perhaps reach out to him. I don't think he comes here much anymore, but he's around.
