Rogor is a commonly used pesticide in the agricultural field. The present study was undertaken to evaluate the lethal toxicity of Rogor, an organophosphorus pesticide, in freshwater fish Channa punctatus (Bloch) and relative behavioural changes after exposing for 96 hours. The regression equation calculated as y = 9.551x + 6.173 and the LC50 value calculated for Channa punctatus was at 0.75 mL/L. During exposure, fish showed faster opercular activity, erecting dorsal and ventral fin, huge secretion of mucus from whole body, etc.
