Abstract
Important oxidative enzyme involved in Kreb’s cycle is succinate dehydrogenase revealed sensitivity to trivalent arsenic chloride in fingerlings of a siluroid, Mystus (M.)vittatus. Estimated succinate dehydrogenase in gills and liver revealed no significant alteration when exposed under sub- lethal concentration of the selective toxicant duriing seven days where as significant alteration was noticed when the fingerlings were exposed after 14 days and 21 days interval. Causes for declining in the succinate dehydrogenase in gills and liver under trivalent arsenic chloride has been discussed.
