Abstract
In the present investigation bioaccumulation of mercury in various tissues of fish Labeo rohita was carried out. The probit mortality analysis disclosed that 57.074 mg/L mercuric chloride exposure for 96 hrs as LC50 dose for the toxicological studies. The comparative account of tissue concentration of mercury resulted in that tissue concentration was higher in brain and kidney upon exposure of LC50 dose of mercuric chloride. However in controlled unexposed fishes collected from natural waters had well below the admissible level for human consumption suggested by WHO.
