Adding RES to the forage should dramatically reduce the parasite problems. Initial RES should be big enough (5"-7") to eat the medium and larger snails. Adult RES are not able to eat adults of some species of snails. RES biomass in the pond will reduce amount of minnows that can be raised in the pond. Adding single sex just male or female RES is an option if small RES are not wanted. Adult RES may also eat some small minnows. Young RES would be good for restocking. Over time and without perodic draining, RES populations could build up to overpopulation type densities.
