Google says that gizzard shad are very susceptible to rotenone at a much lower concentration which would allow selective action. The dose needed to kill gizzard shad is 1/10th of the dose that would kill other panfish and bass. To achieve this the amount of water in the pond would have to be relatively constant and the cost would be high to get 17 acres treated. But at least your target amount needed would be 1/10th of what is used when rotenone is used to target all the fish in the pond.
