AbstractParasitic infestation of carp fish is a major challenge for commercial fish farmers of northwest Bangladesh. Commercial fish farmers of this region are using emamectin benzoate (a plant pesticide) for water treatment of parasite infested fish ponds. The study was conducted to know the practice of using emamectin benzoate (water treatment at the rate of 2µg/L pond water and feed at the rate of 50µg/kg fish for seven consecutive days) impact on zooplanktons, aquatic insects and benthos population in aquaculture ponds. Regular sampling of zooplanktons, aquatic insects and benthos were done and counted at pretreatment and after 1, 2, 5, 10, 15, 21 and 28 days of the treatment for both methods of treatment. Though both the feeding and water treatment with emamectin benzoate was found to be equally successful in killing the target fish parasites, however, the unintended impact of the water treatment was found to be huge on zooplanktons and benthos population. Aquatic insects were also found to be affected partially. Moreover, choice of application method creates a great difference (water treatment requires many times more) in amount of total emamectin benzoate required for the treatment and ultimately used in the water body.
