Interpretive Summary: Two methods of disease control in ponds are biological and chemical treatment. We evaluated each for control of dero worms, an intermediate host of disease in channel catfish. Both treatments were successful in reducing snail populations. The chemical treatment additionally affected the zooplankton population, which would impact fry surivival.
Technical Abstract: Removal of intermediate hosts is one option for control of disease in channel catfish production systems. We evaluated use of predaceous fish (smallmouth buffalo) and chemical treatment (potassium permanganate) to remove snails that serve as hosts protecting Dero worms. Both methods of treatment reduced snail populations effectively, however the use of the chemical treartment reduced zooplankton populations. The use of potassium permanganate would reduce food resources for fry stocked in treated ponds.
