ABSTRACT

Acute toxicities, in terms of median lethal concentrations (LC50), of commercial grade endosulfan on Esomus danricus, a teleost commonly found in shallow streams and floodplain wetlands of  Assam, India at 24, 48, 72 and 96 hours were 22.48, 13.2, 7.97 and 4.94 µg l-1 respectively. Behaviour of exposed fish was noted upto 96 hours of exposure. Effects of three sublethal concentrations of endosulfan on growth and somatic indices during 28 day exposure period revealed a decline in body weight accompanied by a dose and exposure dependent increase in hepato-somatic index and decline in brain and kidney-somatic indices.

Keywords: LC50, endosulfan, organo-somatic index, chronic toxicity
