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: 2-3 days after the above-mentioned disinfection, the water intake is 5 mg / L, the pH value is 7.8-8.5, and the transparency is 30-40 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 open feed to replace shr...

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: 2-3 days after the above-mentioned disinfection, the water intake is 5 mg / L, the pH value is 7.8-8.5, and the transparency is 30-40 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 feed to replace the sh...

Abstract

The invention discloses a method for breeding penaeus vanmamei. The method comprises the steps of pond disinfection, oxygenation, water introducing, shrimp fry selection, and feeding in the stages of growth and development of the shrimp fries to P5, the night before putting of the shrimp fries, about 25 days after putting of the shrimp fries, and the middle and latter periods of breeding. Feeds of corresponding stages are provided according to different nutrition demands of the penaeus vanmamei at different growing stages, so that the penaeus vanmamei can be kept in a stable and healthy physiological status, the bait coefficient of the penaeus vanmamei can be lowered, the growing speed is increased, and the disease resistance of the penaeus vanmamei is favorably improved. The penaeus vanmamei bred by adopting the breeding method disclosed by the invention is high in survival rate and 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...
