The fishing season for swimming crabs is from March to April in spring and from August to November in autumn. September to October in autumn is the fattest period. When swimming crabs are cultured in ponds, the pond water needs to be drained and the bottom of the pond must be turned over. Expose the mud to the sun for disinfection, select live and healthy crab seedlings of similar sizes, and change the water every 5-7 days after stocking. The transparency of the water should not be less than 30 cm.
The fishing season of swimming crabs
The fishing season of swimming crabs is from March to April in spring and from August to November in autumn. September to October in autumn is the fattest period. The crab paste is full and the meat of the male crab is plump. In late October, the swimming crabs will turn into empty-shell crabs after they breed and mate. Breeding technology of swimming crabs
When swimming crabs are cultured in ponds, it is necessary to drain the pool water and turn over the silt at the bottom to expose them to the sun for disinfection. Anti-escape devices are installed at the water inlet and outlet. Pool water is injected into the crab seedlings 2 weeks before they are released. Select crabs with similar sizes and lively ones. For healthy crab seedlings, the density should be controlled at 1,000-1,500 per acre. Daily management of swimming crabs
Change the water every 5-7 days after swimming crab seedlings are released. It is best to use seawater when changing the water. The transparency of the water should not be less than 30 cm. It is best to use fresh water when feeding. Bait, reduce the use of feed, and remove male crabs from July to August to avoid empty shells during mating during the autumn fishing season. Disease prevention and control of swimming crabs
During the breeding period, swimming crabs are susceptible to viral diseases, bacterial diseases and parasitic diseases caused by environmental discomfort. The disease peak period is between May and October. It is necessary to change the water regularly and use machines to increase the concentration of water in the water. Dissolved oxygen, mix immune polysaccharides in the bait and feed it for at least 7 days to improve immunity.
