Impacts of organophosphate pesticide, sumithion on water qualityand benthic invertebrates in aquaculture ponds

---

This experiment was carried out to evaluate the effect of an organophosphate pesticide, sumithion onwater and sediment quality and benthic invertebrates in aquaculture ponds for 120 days. Three treat-ments were tried in duplicate: no sumithion (control), weekly application of 1.0 mg/L sumithion (Lowdose treatment) and 2.0 mg/L sumithion (High dose treatment). Among the different water quality param-eters, transparency, NO3–N and PO4–P concentrations were significantly (p < 0.05) decreased in sumithionhigh dose and low dose, compared to control. The pH, organic matter (%), available phosphorus (mg/L)and total nitrogen (%) of bottom-sediment also did not vary significantly (p < 0.05) among the treatments.Seven genera of benthic invertebrates belonging to Chironomidae, Oligochaeta and Mollusca were iden-tified over the experimental period. The abundances of benthic invertebrates (number per m2) weresignificantly (p < 0.05) decreased in both groups treated with summation, compared to control withoutpesticide. The findings suggest that sumithion had adverse effect on abundance of benthic invertebratesthat might have also negative impact on culture animals in aquaculture ponds.
