Problems solved by technology

[0006] 3. In order to meet the different nutritional needs of prawns or improve disease resistance, excessive so-called nutrients or medicines are mixed in the feed, but they are rarely used by prawns, which not only increases the cost of breeding, but also increases the risk of breeding. The defects and misunderstandings in the farming methods have greatly reduced the benefits of vannamei farming

Embodiment 1

[0028] A culture method of Penaeus vannamei, comprising the steps of:

[0029] (1) Pond disinfection: Disinfect the pond by evenly splashing 50-80kg / mu quickliming slurry; rinse the pond after drying the pond for 3 days, and wash away the lime water; add 5-10cm of water to make the pH value of the pond water 8.0 ~8.6; then spray and disinfect the whole pool according to 200~250g bromochlorohydantoin per mu;

[0030] (2) Aeration: The depth of the pond is about 1.2m, equipped with three 1.5kw power aerators;

[0031] (3) Water intake: 2 to 3 days after the disinfection of the bromine-chloride sea, the water intake is 5 mg / L, the pH value is 7.8 to 8.5, and the transparency is 30 to 40 cm;

[0032] (4) Selection of shrimp seedlings: select shrimp seedlings with a length of 0.8-1.2 cm, and put 370,000 shrimp seedlings into a 12-acre pond; stock the shrimp seedlings at a water temperature of 22-35°C;

[0033] (5) The growth and development of shrimp seedlings to P5: use 14kg ope...

Embodiment 2

[0038] A culture method of Penaeus vannamei, comprising the steps of:

[0039] (1) Disinfection of the pond: Disinfect the pond by evenly spraying 8 kg / mu of bleaching powder; rinse the pond after drying the pond for 4 days, and wash away the lime water; add 5-10 cm of water to make the pH value of the pond water 8.0-8.6; Then spray and disinfect the whole pond with 200-250g bromochlorohydantoin per mu;

[0040] (2) Aeration: The depth of the pond is about 1.2m, equipped with three 1.5kw power aerators;

[0041] (3) Water intake: 2 to 3 days after the disinfection of the bromine-chloride sea, the water intake is 5 mg / L, the pH value is 7.8 to 8.5, and the transparency is 30 to 40 cm;

[0042] (4) Selection of shrimp seedlings: select shrimp seedlings with a length of 0.8-1.2 cm, and put 390,000 shrimp seedlings into a pond of 13 mu; stock the shrimp seedlings at a water temperature of 22-35°C;

[0043] (5) The growth and development of shrimp seedlings to P5: use 15kg open f...

Abstract

The invention discloses a culture method of Penaeus vannamei, which comprises the following steps: pond disinfection, oxygenation, water intake, selection of shrimp seedlings, growth and development of shrimp seedlings to P5, the night before seedling release, about 25 days of seedling release, and the middle and late stages of cultivation The present invention provides the feed of the corresponding stage for the difference of the nutritional requirements of different growth stages of Penaeus vannamei, so that Penaeus vannamei can maintain a stable and healthy physiological state, which can not only reduce the bait coefficient of Penaeus vannamei, improve its growth rate, and It is beneficial to improve the disease resistance of Penaeus vannamei; the cultured Penaeus vannamei has a high survival rate and a high yield.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating Penaeus vannamei. Background technique [0002] Penaeus vannamei is native to the Pacific coast of South America. This species was introduced by the Institute of Oceanology, Chinese Academy of Sciences in 1998. Penaeus vannamei has the advantages of strong disease resistance, high yield, low cost, good meat quality, and strong adaptability. In Jiangsu, Guangdong, Guangxi, Fujian, Hainan and other provinces, large-scale farming has achieved outstanding economic and social benefits. However, since 2002, with the continuous deterioration of the breeding environment and the deteriorating quality of seedlings, a large-scale outbreak of white spot virus has been caused, which has seriously damaged the culture of Penaeus vannamei. This is not only related to the degradation of the quality of shrimp seedlings, but also reveals that my country's shrimp farming technolo...
