The effect of the 50% lethal concentration and of a sublethal concentration (0.3 mg/liter) of mercuric chloride on the activities of succinic, lactic, and pyruvic dehydrogenases in the digestive system of two teleost fishes, Ophiocephalus punctatus and Heteropneustes fossilis, respectively, has been studied at intervals of 96 h and 7, 15, and 30 days. The results show that dehydrogenases are not affected much by short-term exposure. However, the activities of all three enzymes are inhibited by chronic exposure to mercury and maximum inhibition is observed after 15 days of exposure. Among the different parts of the digestive system, the liver is the most affected organ, and of the two fishes, Heteropneustes is more sensitive to mercury treatment.
