This has merit except when large numbers of predators exist in the habitat
they are being introduced into. In the case of barrens topminnows you'd
probably just be feeding Gambusia. In razorback suckers any fish released
that is smaller than 14 inches is fish food for striped bass.

That being said though, I think it could be an excellent strategy to try
if predation wasn't the major reason for the decline in the first place.
