Method for cultivating Penaeus vannamei Boone larvae in earth pond greenhouse

Abstract

The invention discloses a method for cultivating Penaeus vannamei Boone larvae in an earth pond greenhouse, which comprises the steps of digging an earth pond, carrying out pond clearing and sterilization on the earth pond before the earth pond is used, and putting larvae into the earth pond at a density that 40-50 thousand Penaeus vannamei Boone larvae are put into each square meter of the earth pond, wherein cultivation water in the earth pond uses seawater and freshwater directly; and enabling water temperature in the earth pond greenhouse to be stabilized at 24-28 DEG C through ventilation conditions of the greenhouse, and appropriately heating at a condition when the temperature is low, wherein heating equipment adopts an environmental-friendly boiler or an electrical heating bar. According to the invention, 25g bait feed is put at each time for each million of Penaeus vannamei Boone larvae, and the bait feed is put per four hours. The cultivation water in the earth pond is desalted each day, fresh water is added to the earth pond each day, and stress management and water quality control in the larvae cultivation period are reinforced at any time. According to the method disclosed by the invention, the survival rate of the larvae is higher, the cultivation method is more low-carbon, more energy-saving and more environmental-friendly, the natural temperature is more conducive to growth of the larvae, the death rate of the larvae is reduced, and the yield of the Penaeus vannamei Boone larvae is enabled to be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for cultivating Penaeus vannamei seedlings in an earthen pond greenhouse. Background technique [0002] Penaeus vannamei Boone, whose scientific name is Penaeus vannamei, is native to the Pacific coast of South America. Professor Zhang Weiquan of the Institute of Oceanography, Chinese Academy of Sciences first introduced this shrimp from the United States, and broke through the breeding barrier in 1992. From the pilot test to the promotion of breeding throughout the country. Penaeus vannamei is recognized as one of the few excellent varieties, and is favored because of its advantages such as fast growth, antibacterial and environmental adaptability. At present, the culture of Penaeus vannamei has become the pillar industry of my country's aquatic industry. Vannamei is a high-quality high-grade food. Its meat is delicious and nutritious, and it is deeply...

Problems solved by technology

[0003] In recent years, Penaeus vannamei in most areas of our country has been raised in cement ponds. The cost of raising seedlings in cement ponds is not only high, it is not conducive to energy conservation and environmental protection, but also the survival rate of shrimp seedlings cultivated in cement ponds is low, and the quality of shrimp seedlings is not high. ,Low Yield

The temperature of the shrimp pond is not easy to control

These defects in the prior art not only increase the culture cost of Penaeus vannamei, but also increase the risk of culture, and greatly reduce the culture benefit of Penaeus vannamei
