The present study is to determine the bioaccumulation of heavy metals in various organs of the fresh water fish Clarias batrachus exposed to heavy metal water system. The experimental fish were exposed to Cr, Ni, Cd and Pb concentrations for periods of 48 days.the heavy metals Cd, Pb, Ni & Cr were assayed using atomic absorption spectrophotometery and the result were given as μg/g dry Wt. The accumulation of heavy metals gradually increases in liver during the heavy metals exposure period. The heavy metal accumulation in the gills was in the order of Pb>Cd>Ni>Cr, the heavy metal accumulation in the liver was in the order of Pb>Cd>Ni>Cr. The bioaccumulation in kidney and flesh tissues was in the order of Pb>Cd>Cr>Ni and Cr>Pb>Cd>Ni.Abstract
