China is widely distributed in lakes along the north and south coasts, and the only breeding base of Eriocheir sinensis seedlings in China is Chongming Island, because Chongming Island is located at the mouth of the Yangtze River and is also a place where crabs breed. After the 1960s, the output dropped sharply, and it was restored by artificial transplanting and releasing seedlings. September-11month is the peak season of production every year.

The natural distribution areas of Eriocheir sinensis are mainly in northern Asia, western Korea and China. China is distributed from the mouth of Yalu River in Liaoning Province in the north, Jiulong River in Fujian Province in the south and Three Gorges Mouth in Yichang, Hubei Province in the west. As early as 1000 years ago, I had a certain understanding of the living habits of Eriocheir sinensis, especially the law of reproduction and migration. With the artificial cultivation and proliferation of crab seedlings, this crab has spread all over the country, but its quality is most famous in the hairy crabs in Gucheng Lake in the lower reaches of the Yangtze River and Shengfang Crab in Hebei Province. At the beginning of the 20th century, Eriocheir sinensis was transplanted to Germany with seagoing ships, and then spread along the Rhine River, and now it has spread all over the waters of many European countries.

Eriocheir sinensis is delicious and nutritious. This crab can only eat live crabs. After protein in dead crabs is decomposed, it will produce crab venom. Eriocheir sinensis is delicious and nutritious, and has always been regarded as the top grade. Every100g of crab food contains protein 14%, fat 5.9% and carbohydrate 7%. In addition, it also contains vitamin A, riboflavin and nicotinic acid, and its calorific value exceeds the nutritional level of general fish. Eriocheir sinensis is an export variety, which is exported to Hong Kong and Macao. Export ports: Jiangsu, Zhejiang and Guangdong.
