Abstract

Fish was exposed to different concentrations of chlorantraniliprole for different hrs, percent mortality and behavioral responses were studied. The 96 hrs LC50 value of test toxicant to the fish was found to be 16.465mg/l-1. Behavioral patterns were observed in during exposure period, test organism showed normal behavior in control group but jerky movements, hyper secretion of mucus, opening and closing of mouth for gasping, losing scales, hyperactivity were observed experimental group. The toxic effects of the environmental contaminant chlorantraniliprole, on the gill and liver of freshwater fish L.rohita were determined by light microscope. The fish were exposed to sub lethal concentrations (1/10th 96 hrs of LC50) for 15 days. Gills were found to be the most seriously affected organ compared to liver, because of the direct contact with the toxicant. Also the liver is an important organ which breakdown chemicals and as a result, hepatocytic alterations was prominent often among those that are damaged by chlorantraniliprole. No histopathological changes were observed in control group.
