Heavy metals discharged from industries these days are a major source of pollution which has become threat to all forms of life. A measure of metabolism may be a most sensitive parameter since it integrates many factors such as enzyme activity, biochemical contents and physiological response. The ability to accurately characterize enzymes with respect to their distribution and kinetics makes them attractive indices of stress. The concept of Na{sup +}/K{sup +}-ATPase being intimately involved in active transport of ions across biological membranes has gained wide acceptance in recent years. Interference with osmoregulation may restrict the animal's ability to adapt to salinity changes. Several studies have shown that crustacenas are highly sensitive to metal pollutants, particularly when acclimated to low salinities. The present study was initiated to compare the characteristics of Na{sup +}/K{sup +}-ATPase activity in hepatopancreas and gills of crabs Scylla serrata (Forskal) exposed to acute and sublethal concentrations of cadmium chloride for defined periods with those from undosed animals.
