Soundarapandian P, Ravichandran S and Varadharajan D

Study of proximate composition in different sexes is important to know the nutritional status of each sex. In the present study, biochemical composition (protein, carbohydrate and lipid) were studied male, female and berried crabs of Podophthalmus vigil. The protein content was maximum in females (23.47%) when compared to males (21.53%) and berried females (20.93%). The carbohydrate content was significantly higher in berried females (2.76%) and lesser in males (2.09 %) and females (2.06%). The lipid contents were significantly higher in females (1.09%) and berried females (1.05%) than males (0.32%). Ash content was maximum in females (0.99%) and berried female (0.98%) than males (0.31%). The moisture content was maximum in berried females (79%) followed by males (75%) and females (74%). From the results, it is confirmed that organic constituents of the females are nutritionally superior over male crabs.
