Technical Overview: Through the ecological environment of artificial ponds, solve the ecological problems of ponds and crabs; according to the rules of growth and development of crabs, supplement feeding of snails, artificial feeds, etc.; thus improve crab size, yield and aquaculture efficiency.
Increased production and efficiency: In 2011, demonstration and promotion of 180,000 mu were held in Jingzhou, Xiantao, Xianning and Xiaogan culture ponds. The average size of the crab is 140 g/above, the yield per mu is more than 55 kg, the output value of the mu is 2,750 yuan, and the mu is increased by 1,000-1,500 yuan. Technical points:
(1) Grass migration: Before the Ching Ming Festival, plants are planted in ponds, covering an area of ​​60% of the pond's water area. Live snails were transplanted, and 300 kg of mu was cast;
(2) Restocking of crab species: 500-600 pieces of 100-200 pieces per kilogram of crab species;
(3) The feed is used with vegetable feed, animal feed and compound feed;
(4) Disease prevention and control: Prevention is the main method. Preventive measures are used to regulate dredging, disinfection, and use of probiotics to regulate water quality.
Appropriate areas: Crab ponds in plain lake areas and low-lying areas.
