Abstract

The toxicity of carbaryl and malathion to Clarius batrachus check for this species in other resources was studied in a static renewal bioassay for 48 hrs and 96 hrs. Also a chronic dose of 45 days 0.05 ppm malathion and 2 ppm carbaryl was taken to study morphological, physical and behaviroural changes during exposure. The LC50 value of carbaryl for 48 hours was 13.24 ppm and 5.248 ppm respectively and for malathion 48 hours and 96 hours was 0.31 ppm and 0.25 ppm respectively. The fish shows quick response to malathion than carbaryl. The results revealed that malathion is more toxic to Clarius batrachus than carbaryl. @ JASEM
