Hairy crabs can be sold after 5~7 months. Hairy crabs are generally cultivated in wetlands with excellent natural environment, no pollution, convenient water storage, abundant aquatic resources, shrimps, snails, clams and other benthic organisms. A certain number of aquatic plants are planted in the crab pond, which is beneficial to the crab's foraging, habitat, concealment, molting and growth. Regularly transfer water or add water, and the amount of water exchanged depends on the situation.
