Sumithion is an organophosphorous pesticide widely used to control tiger bug in the fish larval rearing pond. The present study was aimed to investigate the effects of sumithion on plankton population abundance in aquaculture pond. The experiment was carried out with three treatments, i.e., ponds with no sumithion (T1), with 1.0 ppm sumithion (T2) and 2.0 ppm sumithion (T3). The water quality p...
