1. The selected pond mouth requires that the pond area is 8 ~ 10 mu, the water source is sufficient, the water quality is good, the water depth is more than 2 meters, and the slope ratio 1: 2.5. A shrimp ditch with a width of 4 ~ 6 meters is opened in the center of the pond to catch waterlogging. According to the scale of aquaculture, the technology of high irrigation and low drainage is adopted to build the water intake and drainage system.

2. Seedling raising, that is, the method of cultivating double-season Macrobrachium rosenbergii. Purchase early-propagated Macrobrachium rosenbergii larvae from late March to early April, intensively cultivate them in plastic greenhouse, and strive to reach the shrimp species specification of 3 cm in the middle and late June; In the middle and late May, the fry of Macrobrachium rosenbergii were purchased and cultivated in a special pond. By mid-August, the specifications of shrimp species reached 3 cm for subsequent stocking. The method of cultivating Macrobrachium rosenbergii in the first crop and Macrobrachium rosenbergii in the second crop includes purchasing Macrobrachium rosenbergii seedlings for stocking in the middle and late May; At the beginning of June, a cage was set up in the culture pond to raise young prawns, and the prawn seedlings were cultured in a special pond. At the end of September, the specifications of shrimp species reached about 3 cm.

3. Rational stocking and breeding of Macrobrachium rosenbergii in two crops: 0.8 ~ 1 10,000 in the previous crop and 0 ~ 25,000 in the following crop. Macrobrachium rosenbergii is cultivated in the previous crop and Macrobrachium rosenbergii is cultivated in the next crop, with an yield of 20,000-25,000 prawns per mu. Before stocking, clean and disinfect the shrimp pond, cultivate basic bait and transplant aquatic plants. Choose sunny morning stocking, pay attention to the temperature difference should not be too large.

4, bait feeding, feeding special compound feed. Macrobrachium rosenbergii culture is mainly based on a series of compound feeds, with appropriate addition of small fish and shrimp. Feed is mainly given once in the evening, accounting for about 70% of the whole day. Feed in the deep water area during the day, feed in the shallow grass area at night, and feed at regular time, fixed point, fixed quality and quantitative. The daily feeding amount of Macrobrachium rosenbergii is 5% ~ 10% of the weight of pond shrimp, and that of Macrobrachium rosenbergii is 3.5%.

5. Water quality management: In May and June, at the initial stage of rearing shrimp seedlings or fingerlings, the water depth of the pool is kept at 0.8m. In the high temperature season from July to September, the pool is filled with water. In rainy and muggy weather in autumn, according to the water quality, fresh water is injected every 7 ~ 10 days, and the water is changed every time13. Strengthen water quality inspection and pond inspection at ordinary times.

6. Timely fishing: Macrobrachium rosenbergii has two shrimps, the first shrimp in August and the second shrimp in early June 10. Macrobrachium rosenbergii, Macrobrachium rosenbergii and Macrobrachium rosenbergii, started to catch the big ones and leave the small ones in mid-August, and went public in stages. Shrimp catching went on the market in May of the following year. Conditional can adopt the method of temporary rearing in plastic greenhouses, and choose some commercial Macrobrachium rosenbergii to sell when the price is high around the Spring Festival.
