1. The culture technology of White Penaeus vannamei is as follows: Pond culture requirements: The pond for raising White 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 good drainage. system to facilitate water changes in shrimp ponds. It is also necessary to ensure that there is sufficient water source in the pool, the water quality must be clean, and it must contain sufficient nutrients to meet the cultivation needs of Penaeus vannamei. Finally, oxygen-increasing equipment should be added to the shrimp pond to supply sufficient nutrients to the shrimp pond and increase the dissolved oxygen content of the shrimp pond.
2. Sterilization of shrimp ponds: Before stocking shrimp seedlings, the living habits and growth characteristics of Penaeus vannamei, as well as the hygiene of the shrimp pond after breeding, should be considered. Disinfect and sterilize shrimp ponds. One month before shrimp seedlings are released, an appropriate amount of quicklime should be added to the shrimp pond for disinfection, and a proportion of bleaching powder should be added to the shrimp pond seven days in advance. You can also add certain water-quality fertilizers to the pond, such as water fertilizer, etc., which can provide sufficient nutrients in the shrimp pond and create a good living environment for the shrimp.
3. Shrimp seed selection: Penaeus vannamei originally lived in the salt water of South America, but it was introduced to China and began to be cultured in fresh water. Therefore, since the water for culture is fresh water, you must also choose to go through the process when selecting shrimp larvae. Watered down. After avoiding the selection of shrimp seedlings, the shrimp will have difficulty adapting to the freshwater pond environment, resulting in large-scale death. When selecting shrimp seedlings, you should try to ask experienced farmers based on the environment around the shrimp pond and seasonal characteristics. Grasp the market demand and choose varieties with high market demand.
4. Water quality adjustment: When cultivating Penaeus vannamei, it is not easy and difficult to change the water, so the frequency of water changes will be relatively low. During the breeding process, we need to strengthen our understanding of the water quality in the shrimp pond, study the changes in water quality in the pond through old water changes, and ensure clean water quality by changing water to reduce feed and other methods. According to the different water temperature changes in each season, we should grasp the changes in the four seasons. When the water temperature changes, we should take measures to prevent the impact of water temperature changes on shrimps and strengthen the regulation of water quality, which will play a certain role in shrimp farming.
5. Feeding: Generally, cheap small shellfish or fish paste is fed, and some compound feeds can also be fed. The feeding amount should be based on the size of the shrimp, survival rate, water quality, environment, feed quality, etc. Comprehensive judgment of factors. Feed multiple times a day, with evening feeding accounting for 60% to 70%.
6. Daily management: Inspect the pond three times a day, pay attention to the water color and the activity, growth and eating conditions of the white shrimp. Inspect the pond once in the morning, noon and evening to adjust the feeding amount and whether to turn on aeration. machine.
