A Complete Guide to Whiteleg Shrimp Farming Techniques

Whiteleg shrimp is also called Vannamei shrimp, with an average lifespan of more than 32 months and high yield per unit, making it very popular among farmers. Today the editor will introduce the farming techniques for whiteleg shrimp.

1. Pond requirements

The pond for farming whiteleg shrimp must reach a certain depth. Usually the depth of the shrimp pond is about 1.5-2 m, ensuring that the shrimp pond has a good drainage system to facilitate water changes, and it is also necessary to ensure that the pond has an adequate water source. The water quality must be clean and contain sufficient nutrients to meet the needs of whiteleg shrimp farming. Finally, aeration equipment should be added to the shrimp pond to supply enough oxygen to the pond and increase the dissolved oxygen level, which can greatly improve the survival rate of the shrimp.

2. Sterilising the shrimp pond

Before stocking the shrimp fry, the shrimp pond should be disinfected and sterilised according to the living habits and growth characteristics of whiteleg shrimp as well as the sanitation issues in the pond after farming. One month before stocking the fry, add an appropriate amount of quicklime to the shrimp pond for disinfection, and bleaching powder should be added to the shrimp pond at the specified ratio seven days in advance. A certain amount of water fertiliser, such as Shuifeibao, can also be added to the pond. This can provide sufficient nutrients in the shrimp pond and create a good living environment for the shrimp.

3. Selecting shrimp fry

Whiteleg shrimp originally lived in the salt water of South America, and only after being introduced to China did freshwater farming begin. Therefore, because the farming water is freshwater, the shrimp fry selected must also be those that have undergone desalination treatment. Otherwise, after selecting the fry, the shrimp may find it difficult to adapt to the freshwater pond environment, leading to large-scale death. When selecting shrimp fry, base the choice on the surrounding environment of the shrimp pond and the characteristics of the season. For other unclear issues, try to ask experienced farmers. At the same time, when selecting shrimp fry, it is necessary to understand market demand and choose varieties with large market demand.

4. Water quality regulation

When farming whiteleg shrimp, changing the water is not very easy, so the frequency of water changes is relatively low. During the farming process, we should strengthen our understanding of the water quality in the shrimp pond, study the changes in water quality through the old water from previous water changes, and ensure clean water quality by methods such as water changes and reducing feed. In addition, according to the different water temperature changes in each season, grasp the changes across the four seasons. When the water temperature changes, measures should be taken to prevent the impact of water temperature changes on the shrimp and to strengthen water quality regulation, which has a certain effect on shrimp farming.
