Cadmium is considered as a potent toxic metal to a varied variety of creatures;
the main impacts are in the development and replica process. Dissolved
cadmium salts released in drainage water from mines may represent a
significant threat to aquatic wildlife. Pollutant stress leads to significant
modification in biochemical and physiological functions in reproductively
energetic aquatic animals and further interrupt reproductive processes. In the
edible crab Scylla serrata, the protein, carbohydrate, lipid, marker enzymes
and phosphatase have been estimated in the ovary, hepatopancreas, muscle
and haemolymph during several periods of the ovarian maturation. The results
revealed that, there were declined levels of protein, carbohydrates, lipid and
phosphatase in the cadmium reared crabs when compared to the control. The
marker enzymes were augmented in the haemolymph. The observed results of
this experiment were tested statistically.
