1. Breeding facilities. The appropriate pond area is 4-10 acres, with a depth of 1-1.5 meters and a slope ratio of 1:2.5. The bottom of the pond is flat, and loam is the best substrate. The soil on the slope of the pond is relatively hard. The pond has good water retention and the water level is easy to control. The water source is sufficient and the water quality is pollution-free. According to the pattern of high irrigation and low drainage, build inlet and drainage channels to ensure that irrigation can come in and drainage can be discharged.

2. Preparation before stocking. Thoroughly clean and disinfect the pond. 20-30 days before stocking shrimp seedlings, drain the pond water, remove excessive silt, repair the pond ridge, and use 75 kilograms of quicklime per acre or bleaching powder, bleaching powder essence and other drugs to thoroughly clean and disinfect the pond.

3. Stocking of shrimp seedlings and shrimp seeds. Summer stocking mode. Mainly the first batch of juvenile shrimp hatched in the year of stocking. The stocking time is in mid-to-late July, and the size of the juvenile shrimp is more than 0.8 cm. Stocking 30,000-40,000 tail per acre.

4. Scientific feeding. In the juvenile shrimp stage, they feed on rotifers, cladocerans, copepods, and aquatic insect larvae, while in the adult shrimp stage, they eat both animal feed and plant feed. After shrimp seedlings and shrimp seeds are stocked, fertilizer should be applied in a timely manner to improve the water quality. During the rapid growth stage of crayfish from August to October, feed more bran, bean cake and green feed, and appropriately feed animal feed.

5. Daily management. Establish a pool inspection system. Patrol the pool every day and take timely measures if any abnormalities are found. Prevent escape and disease. Inspections will be strengthened during the flood season to prevent escaping shrimps. Carry out disease prevention and control and enemy removal work.
