The width range of male shells were 31.5-122.5 mm and weight range were 53.75-286.08 gram, while the females shells have width range of 78.4-120.5 mm and weight range of 69.38-229.08 gram. Fecundity of mangrove crabs (Scylla serrata) ranges between 345,923-1,472,639 eggs with mean value of 646.194. Diameter of the egg curve shows that the mangrove crabs were total spawner, which means totally discharge their eggs.
