The invention discloses a hairy crab three-dimensional breeding method. According to selection of
juvenile crabs needed by the method, the age of the
juvenile crabs should reach 6 days or above,
desalination should be conducted for 4 days or above, and the
salinity should be 3 or below; the body is healthy and strong, has a hard shell feeling when being held by hands, has strong
vitality and is golden yellow; and individuals are uniform in size, and the specification is about 18*104 / kg. Three-dimensional water tank breeding is adopted in the method, fine sand,
sludge and aquatic plants are utilized in a water tank to create a good
living environment, the aquatic plants are beneficial to foraging,
habitat, concealment, molting and growth of river crabs, meanwhile, a large amount of food isprovided for the crabs, due to
plankton in water, mutual food
seizing of the crabs can be reduced, and the
survival rate of the crabs can be improved. Meanwhile, quick
lime is added into water,
pesticide is sprayed to the whole area, the morbidity of the crabs is reduced, the quality of the crabs is improved, lamplight can be installed in the water tank according to the catching method, gatheringcatching can be achieved, and therefore the catching
survival rate of the crabs can be increased.
