DD1 folks have done rotenone apps for selective removal of Gshad. In fact I shocked Ray scott's Presidential lake after he had performed a selective treatment. Yes it killed some bass and other species but it also killed thousands and I mean thousands of Gshad. The bass bounced back with great recruitment of bass first time in a couple of years.
Now to these recommendations. I cut my teeth in my start of my career fighting clients on tshad. The thoughts were that tshad compete with bluegill for food. Truth is when lakes have tshad the bluegill population is much higher due to lack of bass predation. In other words more bluegill survive due to bass eating tshad. So these recommendations are not common I will say that. If your goals are good bass growth you need both shad and bluegill. Stock more bluegill don�t rid of shad. Something may be limiting your bluegill but don't think it is Tshad. Secondly you better know what you�re doing. It is tough to apply just the right amount evenly to kill shad and not kill other species. I probably would not even do it for a client in fear of killing his bass and I do this for a living. Just my two cents.
