Acute toxic effects of acephate on freshwater fish Puntius sophore (Hamilton)
PJ Gavit and RD Patil
The present study deals with the acute toxic effects of an organophosphate insecticide Acephate on freshwater fish P. sophore. The fish were exposed to Acephate to determine the LC50 values. The static bioassay experiments were carried out by Finney’s method (1971). The fish was exposed to different concentrations of Acephate and the result showed the LC50 values at 24, 48, 72 and 96 hours were 1762 ppm, 1509 ppm, 1281 ppm and 1117 ppm respectively.
The results of the present investigation depict that Acephate has very low toxic effects on the fish P. sophore.
