Three-eye crabs that have mated and matured ovaries but have not laid eggs have higher nutritional value, and are richer in protein, fat and vitamins, which can be compared with river crabs in autumn and winter. When eating crabs, it is necessary to clean the surface impurities with a brush, remove the inedible parts such as gills, sandbags and internal organs, and steam them at high temperature before eating.
