Any data on HSB, mosquito fish, and fatheads in an unfed pond?
Just an idea:
You'd have to restock HSB periodically but overall it would seem seem easier to manage since they won't reproduce. Since HSB would be the top predator and have fairly small mouths for their size, smaller/less expensive HSB could be added to replenish those removed. HSB put up a heck of a fight, are easy to clean, and are quite tasty. Fluctuating water levels wouldn't effect the forage fish much either. If growth of the HSB is less than needed, pellets could be an option later.
