Penaeus vannamei is a tropical shrimp species. The optimum growth water temperature is 22°C to 28°C. The growth rate is fast. The culture can be listed for 70 days. The general breeding cycle takes about 100 days from the preparation of the clear pond to the harvest of the shrimp and it takes about 100 days. During this period, each link must be seized to ensure the high yield and efficiency of shrimp farming. The pond is prepared to drain the pool water, remove the mud, repair the pool, and put it into the drainage system. 2 The pond was exposed to dry and hard cracks for 15 days to 20 days. 3 2 weeks before seedling (after the shrimp enters the holding pond), a small amount of water shall be injected first. After dissolving 100 kg of quick lime per acre, the bottom of the pool shall be sprinkled evenly, and the inlet water shall cover the entire bottom of the pool every other day. Chlorine oxide and soaked 50kg tea seed cake were splashed in the whole pond. After 2 days to 3 days, disinfected water was released and the sun bath was used for 3 days to 5 days. 4 7 days to 10 days prior to planting, the pond is filled with water 0.8 to 1 meter, 200 milliliters of “disinfected purified water solution†per acre is used to disinfect, and 3 days to 5 days before planting, with “pond detoxification treasure†per acre 500 Spilled milliliters to degrade the residual chlorine, heavy metals, ammonia nitrogen, nitrite and other harmful substances in the pool water. 5 Cultivate natural food. 3 days to 5 days before planting, 200 ml of “Amino Acid fertilizer essence†or 1000 ml of “Diversion Water King 2†Quanchiposa per acre, fertilize the water quality, and cultivate rotifers, etc., are used as the palatable food for juvenile shrimp. Shrimp stocking 1 stocking density: about 5 acres of intensive breeding ponds 100,000 to 120,000 acres, 5 acres to 20 acres of ponds put 70,000 to 80,000, more than 20 acres of ponds put 60,000 to 70,000. 2 Shrimp requirements: clean, no body attachment; long figure appearance, back bow when swimming; head black and white, thick and obvious intestinal; responsive; nursery pond water is golden yellow, no floating seedlings, pH value Between 7.8 and 8.4; size 0.8 cm to 1 cm; the temperature difference between nursery pond and pond water is less than 5 °C. 3 Set up holding pool: In the southeast or northwest corner of the pond, use a plastic film or color strip cloth to block the holding pool, and prepare the inflatable aeration facility. The holding pool has a water depth of about 0.8 meters. The area is calculated according to the total stocking capacity of Datang. 3000 to 5000 shrimps are reared per square meter. 4 Holding pool water transfer: Add 2.5 kg to 3 kg of coarse salt per ton of water, add trace elements at the same time, and then use “Efficient Living Bacterial Fertilizer Water King†and “Yishhuibao†fertilizer water. 5 Holding period management: 1 day to 2 days after transplanting, every 100,000 seedlings feed 15 grams to 20 grams of shrimp slices, 4 meals a day; after 7 days, use 150 grams of vitamins and 150 grams of Yishuibao and 100 grams of glucose to sprinkle. At the same time, add 2 grams of glucose and 2 grams of Vc per kilogram of feed. 6 Datang Stocking: Holding for 10 days to 15 days, when the average size of the shrimps reaches 2 cm or more, the fence can be removed and the shrimps can gradually enter the whole pond.
