Identification method of hairy crab in Yangcheng Lake

Hairy crabs are called "old hairy crabs" by Chongming people because their two large claws are as fluffy as hair. It was born in the waters of the Yangtze River Estuary on Chongming Island. In all the major rivers and lakes in the world, there are more than 300 species of crabs, of which about 20 species are edible, and the most famous is the Chinese mitten crab.

Every winter, Chinese mitten crabs swim to the waters near Chongming Island, where salt and fresh water are handed over to breed, and then the crab seedlings are caught on the island by fishermen of Chongming Island. When crab farmers raise crabs to buttons, called buckle crabs, farmers from Yangcheng Lake and farmers all over the country come to Chongming Island to buy and bring them back to raise them, and then after a lot of publicity, people mistakenly think that crabs were born in Yangcheng Lake. In fact, the real hometown of hairy crabs is in the waters near Chongming Island.
