Litopenaeus vannamei shrimp farming technology.
I. Introduction. Litopenaeus vannamei, also known as vannamei, is one of the most widely farmed shrimp species in the world. Because of its rapid growth, strong adaptability, delicious meat and other characteristics, it is deeply loved by consumers. In order to meet the market demand and improve the efficiency of aquaculture, it is very important to master the cultivation technology of Penaeus vannamei.
Second, the selection of breeding environment.
1.Pond conditions: Choose a place with flat terrain, quiet environment, sufficient water source and fresh water quality to build the pond. The area of the pond is generally 5 10 acres, and the water depth is 15~2.5 meters, the bottom silt does not exceed 20 cm.
2.Water quality requirements: In the process of breeding, the quality of water quality directly affects the growth and survival rate of shrimp. Therefore, it is necessary to regularly test the water quality to ensure that the pH value, dissolved oxygen, ammonia nitrogen, nitrite and other indicators are within the appropriate range.

3. Selection and stocking of shrimp seedlings.
1.Shrimp seedling selection: Choose healthy, vigorous, and neat shrimp seedlings. When buying shrimp seedlings, pay attention to check the body surface, gills, intestines, etc. of shrimp seedlings to ensure that there is no disease.
2.Stocking density: Determine a reasonable stocking density according to pond conditions, water quality conditions, feed management and other factors. Under normal circumstances, 23,000 shrimp seedlings are stocked in each mu of ponds.
Fourth, feed feeding.
1.Feed selection: Choose good quality and nutritionally balanced feed. The feed should contain sufficient nutrients such as protein, fat, vitamins and minerals.
2.Feeding method: According to the growth stage, feeding habits, weather conditions and other factors of shrimp, formulate a reasonable feeding plan. In general, feed 2 to 4 times a day, with small and frequent meals. At the same time, the feeding amount should be adjusted in time according to the feeding situation of the shrimp to avoid waste and pollution of water quality.

5. Disease prevention and control.
1.Preventive measures: Regular disinfection of ponds, replacement of new water, keeping water fresh and other measures can effectively prevent the occurrence of diseases. In addition, reasonable feeding and enhancing the immunity of shrimp are also important means to prevent diseases.
2.Common diseases and control: Common diseases of Penaeus vannamei include white spot disease, black gill disease, erythrosome disease, etc. Once the disease is found, it is necessary to take measures in time**. Methods include medications**, water quality regulation, and improvement of the feeding environment. At the same time, attention should be paid to preventing the spread and spread of diseases.
Sixth, daily management.
1.Pond patrol observation: Patrol the pond at least twice a day to observe the activities of shrimp, feeding conditions, water quality changes, etc. Problems should be dealt with in a timely manner.
2.Water quality management: Regularly test water quality indicators to maintain stable and appropriate water quality. Adjust the frequency and amount of water changes in a timely manner according to the water quality conditions.
3.Feed management: adjust the feeding amount and feeding time in time according to the growth stage and feeding situation of shrimp. Avoid feed waste and polluted water quality.
4.Pest control: Regularly check the health status of shrimp, and take timely measures to carry out diseases when they are found. At the same time, it is necessary to do a good job in the prevention of diseases.
7. Harvest and sales.
1.Harvest time: The harvest time is determined according to the growth rate of the shrimp and the market demand. In general, the breeding cycle is 3-4 months.

3.Sales channels: You can choose to sell directly to buyers or through channels such as e-commerce platforms. Attention should be paid to ensuring the freshness and quality of the shrimp during the sales process.
8. Summary and Suggestions.
Litopenaeus vannamei shrimp farming technology is a highly integrated industry, which requires a wide range of knowledge and skills. In the actual breeding process, we should pay attention to improving the level of water quality management, selecting appropriate feed and feeding methods, and doing a good job in disease prevention. At the same time, it is necessary to pay attention to market demand and changes, and formulate reasonable breeding plans and sales strategies. Only in this way can we obtain better economic and social benefits.
The above is an introduction and analysis of the cultivation technology of Litopenaeus vannamei. It is hoped that some reference and help can be provided to those engaged in this field. At the same time, it is also recommended that relevant departments and institutions should strengthen the research and promotion of Penaeus vannamei shrimp farming technology to promote the healthy development of the industry.
