Problems solved by technology

[0003] The existing culture technology of Penaeus vannamei generally has the following problems: due to water pollution and virus infection, the survival rate of prawns is very low; in order to revitalize the shrimp farming industry, farmers will frequently put water disinfection into the breeding ponds to prevent shrimp diseases With the purification agent, the whole pool is usually splashed, and then the chemical agent is discharged by changing the water regularly. This method often consumes a lot of energy and water, and the pollution is serious

Abstract

The invention discloses a culture method for improving the yield of penaeus vannamei. The method comprises the following steps: 1, a cuboid-shaped pool with the depth being 1.2 to 1.6m and the area being 2 to 4mu is selected; irrigation channel bodies are arranged in the pool; steel wire nets are arranged between the adjacent irrigation channel bodies; the pool is separated into a plurality of culture pools by the irrigation channel bodies and the steel wire nets; a plurality of holes are formed in the two opposite side walls of the culture pool; 2, the pool is under the blazing sun for quite a long time; first disinfectant, first medicine liquid and second disinfectant are used to sequentially coat the pool for disinfecting the pool; 3, the water temperature of the pool is controlled to be 22 to 30 DEG C; the pH value is controlled to be 7.6 to 8.6; the salinity is controlled to be 0.6 to 0.8 percent; then, penaeus vannamei fries are put into the culture pool; 4, after the penaeus vannamei fries are put, the penaeus vannamei in the culture pool is disinfected once every 3 to 5 days. The culture method has the advantages that the self immunity and resistance of the penaeus vannamei can be enhanced; the growth speed of the penaeus vannamei is accelerated; the yield of the penaeus vannamei is improved.

Description

technical field [0001] The invention relates to the field of aquaculture. More specifically, the present invention relates to a culture method for increasing the output of Penaeus vannamei. Background technique [0002] Penaeus vannemei, also known as Penaeus vannemei, belongs to the phylum Arthropoda, Crustacea, Decapod order, Swimming order, Penaeidae, and the genus Penaeus. Produced in the coastal waters of South America, it is distributed along the coasts of Ecuador, Panama, Colombia, Peru, Chile, Nicaragua and other countries. Its meat is tender and delicious, and it is the main cultured shrimp in South America. Penaeus vannamei also occupies an important position in the world's shrimp farming industry. It is listed as the three economic shrimps with the largest farming area and the highest output in the world, together with Chinese shrimp and Banjie. Penaeus vannamei was introduced into my country from South America in the late 1980s, and has been cultured in Jiangs...
