摘要：The lotic aquatic environment has been polluted by effluents wastes having toxic trace metals from anthropogenic activities. A major portion of these toxic metals accumulates in the body of aquatic organisms, hence these organisms are often considered as potential indicators of aquatic metal pollution. These metals are harmful to animal itself and alsoto consumers in the food chain after a permissible concentration. Fishes of being end consumers in the aquatic food chain are used as the indicators of heavy metal enrichment. Much attention has been paid to biomonitoring of these trace metals after minimata diseases caused by mercury and cadmium contamination in the aquatic environment. Studies on the heavy metal contents in fishes of various localities have been reported. The riverine fishes of the district Raebareli despite the fact that the both rivers Ganga and SaiRiver highly sensitive for metals pollution and contribute more than half in total fish production of this district.
