Another method is to put the bundled crabs into a foam box one by one, add ice water without crabs, and cover with a foam cover. Both methods can make hairy crabs live in the refrigerator for a longer period of time, thus prolonging the preservation time, but it is recommended to eat them as soon as possible, because the longer they are preserved, the more they will be consumed, and the meat will not be so full, and the taste will gradually fade after 3 days.
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. Among them, the hairy crabs produced in Taihu Lake, gaoyou lake and Yangcheng Lake in the lower reaches of the Yangtze River are top grade, and 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. At present, hairy crabs have been introduced to all the Great Lakes and cultivated near the Yangtze River estuary. After growing into young crabs, they migrate against the Yangtze River and grow in the tributaries of lakes and rivers in the lower reaches of the Yangtze River. The name of hairy crabs comes from Wu dialect.
