Hairy crab is a kind of river crab, and its scientific name is Eriocheir sinensis. Widely distributed in the long coastline from southern Liaoning to the Pearl River in northern China, the Yangtze River system has the largest output and the most delicious taste. Generally speaking, hairy crabs refer to Eriocheir sinensis in the Yangtze River system.
In the past, hairy crabs grew near the Yangtze River estuary. After growing into young crabs, they migrated against the Yangtze River and grew in the tributaries of lakes and rivers in the lower reaches of the Yangtze River.
The origin of the name of hairy crab: It is said that before catching crabs, a large gate was built with bamboo branches and straw, and a net was laid on one side of the gate. At night, we light lanterns to lure the crabs in the lake to the gate and throw them into the net, so we call them "hairy crabs".
