The crab is a famous delicacy in Shanghai cuisine and is prized for the female crab roe. The crab meat is believed by the Chinese to have a "cooling" (yin) effect on the body.

Chinese spend hundreds of yuan just to taste a small crab from Yangcheng Lake which are a considered a delicacy. Most of the Yangcheng crabs are exported to Shanghai and Hong Kong, and high-profit foreign markets.

Therefore, the farming and post-harvesting of the species needs proper management if it is used as a food.[
