The effects of a sublethal concentration (7.66 mg/L) of carbofuran, were assessed on Clarias batrachus. The fish were exposed to 7.66 mg of carbofuran/L for 6 days. After 6 days, fish were released into carbofuran-free water in order to study the recovery pattern. Proteins were decreased in gill and kidney and recovery was greater in gill than in kidney. Total amino acids were increased in both tissues. Ammonia level declined in gill and enhanced in kidney throughout the study period. The activities of all enzymes measured were induced in both tissues, except for aspartate aminotransaminase, which was inhibited in gill tissues.
