Culture technology of Penaeus vannamei

Penaeus vannamei, also known as Penaeus vannamei, has an average life span of more than 32 months and has a high unit yield, which is very popular with farmers. Today, the editor will introduce the culture techniques of Penaeus vannamei.

1. Requirements for pond maintenance

The pond for the culture of Penaeus vannamei must reach a certain depth, usually the depth of the shrimp pond is about 1.5-2 meters, to ensure that the shrimp pond has a good drainage system, to facilitate the exchange of water in the shrimp pond, but also to ensure that there is an adequate source of water in the pond, and the water quality should be clean. it contains sufficient nutrients to ensure the culture needs of Penaeus vannamei. Finally, oxygen equipment should be added in the shrimp pond to provide sufficient nutrients to the pond. Increase the amount of dissolved oxygen in shrimp ponds, which can greatly improve the survival rate of shrimp.

2. Sterilization in shrimp ponds

Before stocking shrimp fry, disinfection and sterilization should be carried out in shrimp ponds according to the living habits and growth characteristics of Penaeus vannamei, as well as hygiene problems in shrimp ponds after culture. a month before the shrimp fry was released, an appropriate amount of quicklime should be added to the shrimp pond, and the proportion of bleaching powder should be added to the shrimp pond seven days in advance, and certain water quality fertilizers such as Shuifeibao can also be added to the pond. This can make the shrimp pond to achieve sufficient nutrients, for shrimp to create a good living environment.

3. Selection of shrimp fry

Penaeus vannamei originally lived in the salt water of South America, but only began freshwater culture after it was introduced into China, so because the cultured water is fresh water, it is necessary to choose desalinated shrimp fry to avoid choosing shrimp fry. It is difficult for shrimp to adapt to the freshwater pond environment, resulting in large area death. When choosing shrimp fry, according to the surrounding environment and seasonal characteristics of shrimp pond, etc. Other questions that you do not understand should be asked by experienced farmers as far as possible. at the same time, when choosing shrimp fry, you should grasp the market demand and choose the species with large market demand.

4. Water quality regulation

In the culture of Penaeus vannamei, it is not easy to change water, so the frequency of changing water will be relatively low. in the process of culture, we should strengthen our understanding of the water quality in the shrimp ponds and study the changes of the water quality in the ponds by changing the old water before. through changing water to reduce feed and other methods to ensure clean water quality, and according to different seasons of water temperature changes, grasp the changes of the four seasons When the water temperature changes, measures should be taken to prevent the impact of the change of water temperature on shrimp and strengthen the regulation of water quality. Shrimp culture plays a certain role.
