Summary:Acute toxicity of organophosphate pesticide Metasystox has been studied on freshwater fish Nemacheilus botia. Thefishes have been used for many years to determine the pollution status of water. Static bioassays were performed onfreshwater fish, N. botia to evaluate the median lethal concentrations of Metasystox (Oxydemeton-methyl) for 24, 48,72 and 96 hrs. The LC50 values were 10.3, 9.131, 7.884, and 7.018 ppm after 24, 48, 72 and 96 hours respectively.The results show that the LC50 values decreased with increase in exposure period.
