Background
Eriocheir sinensis (Eriocheir sinensis H.Milne-Edwards) is an economic crab, also called river crab, hairy crab, clean water crab and hairy crab. Is a staple food of China's long-standing name, and is used as animal feed for various kinds of crabs, such as fish, shrimp, snail, clam, worm, earthworm, insect and larva.
The crab contains more vitamin A, which is helpful for skin cornification; can also be used for treating rickets in children and osteoporosis in the elderly for supplementing calcium. China is widely distributed in lakes in various places of the south and north coastal areas, wherein the water system of Yangtze river has the largest yield and extremely delicious taste, and is always called as the crown of crabs. Especially, the Dongting lake hairy crabs, Taihu lake hairy crabs, Yangcheng lake hairy crabs, Changding lake hairy crabs and the like are the most famous.
However, the eriocheir sinensis has higher requirement on water quality, can be generally cultured only in large-scale lakes, and the culture density is strictly controlled, and the cultured eriocheir sinensis mainly finds food naturally, and the quantity and frequency of the baits manually input are strictly controlled, so that the water quality deterioration caused by excessive feeding is prevented, and the large-area death of the eriocheir sinensis is prevented.
The growth speed and the output of the eriocheir sinensis are seriously influenced by the reasons, so that the Taihu hairy crabs, Yangcheng lake hairy crabs and Changdong lake hairy crabs become promising and inaccessible food for the ordinary people.
