Abstract

Water is essential to life and to human existence. The ability to predict the effects of pollutants or chemicals on organisms and to extrapolate toxicant effects from laboratory to population and community levels has become a very important factor. The Indian major carp Labeo rohita was exposed to lethal (1.4μg/l) and sub-lethal (1/10th of lethal) concentrations for 24hrs, 5th and 10th days of Pyraclostrobin (20%WG) to examine the SDH and LDH enzymatic activity, in different tissues like gill, liver, kidney, brain and muscle and control group were also maintained. The SDH enzyme activity levels increased and LDH enzyme activity levels decreased when compare with controls.
