ABSTRACT: Effects of heavy metals on fish are multidirectional and manifested by numerous changes in the physiological and chemical processes of their body systems. 11 Nalas (drains) carrying the industrial and domestic waste in Pauna River from Pimpri-Chinchwad Municipal Corporation area. Metal Plating industries are the main source of cadmium pollution in river. Cadmium metal content were analyzed by Atomic Absorption Spectroscopy (Perkin Elmer model No. 3030 USA) and values are expressed in ppm from water sample and various organs of two fresh water fish species Ompok bimaculatus and Puntius sarana sarana collected from four sampling sites on Pauna river. The maximum Cd content found in kidney (1.5ppm) was considerably higher than gill (0.65ppm), muscle and liver (0.60ppm) and ovary (0.5ppm). The Cd contents in the organs was in the order of kidney > gill > liver > muscle > ovary. The present investigation is useful to find out the indicators of cadmium pollution in river water habitat.
