Why not a campaigne to substitute other species that do a better job.
There are several types of native fishes that do a better job than
Gambusia - Topminnows are probably the best followed by Enneacanthus
sunfishes , Fliers (Centrarchus macropterus) and Mudminnows (Umbridae).
Another bonus is that most of the areas where Nile Virus is a concern
support indigenous populations of these fish so it would be an easy
matter for the states or licensed fish culturalists to propagate and
distribute stocks from local genotypes. This would help conserve local
species and minimize the chances for introducing new diseases and
foreign genes into wild populations.
