The invention discloses a method for identifying a wild population and a cultured population of parent crabs of eriocheir sinensis based on morphological parameters. Measurement is made on the back face of carapace and an ambulatory leg. The method is characterized in that morphological measurement parameters of female crabs are L2, L4, L6, F15 and F44, and the morphological measurement parameters of male crabs are L2, L15, F11, F33 and F44; an identification formula, D=66.613L2+31.203L4-43.969L6-159.018F15+34.628F44+2.278, of the female crabs is created by using the L2, L4, L6, F15 and F44; an identification formula, D=83.669L2-70.977L15-26.518F11+72.540F33+44.416F44+26.146, of the male crabs is created by using the L2, L15, F11, F33 and F44; when D is greater than 0, the population is the wild population; and when D is less than 0, the population is the cultured population.
