ABSTRACT

Fishes are aquatic and poikilothermic animals. Hence, their existence and performance is dominated by the quality of their environment. Pollution of water bodies forces them to acclimatize to various factors thus imposing a considerable amount of stress on their lives. Phosphatase is known to be sensitive to metal exposures and can be used to predict metal toxicity. The acid phosphatase (ACP) and alkaline phosphatase (ALP) enzyme activity brought an decrease in acid and alkaline phosphatase (ACP and ALP) in Liver and Kidney when a freshwater fish Labeo rohita exposed to Heavy Metal concentration as compared to the control group. The various concentrations of the heavy metals were found to alter the acidic and alkaline phosphatase activity in the studied organs. Hence, the results from present investigations may be useful in the assessment of environmental stress in the aquatic ecosystem.
