Chinese Mitten Crab Sexing and Measuring
Sex
The sex of a crab is indicated by the width of its abdomen (shaded area) which curls around the crab's underside. The male crab has a narrow, triangular abdomen, while the female has a much broader abdomen.
Size
The size of a crab is determined by measuring its carapace (back) width. The carapace width is the distance across the crab's back at the widest point.
