Embodiment 1

[0030] Cultivation system:

[0031] Such as figure 1 As shown, a high-yield culture system of Penaeus vannamei includes a greenhouse pond, a water circulation system and a sewage system located at the bottom of the greenhouse pond; the greenhouse pond is also equipped with a comprehensive aeration system and an automatic cruising bait feeding machine, and is connected to a boiler heating facility .

[0032] Greenhouse pool area 11000m 2 , the water depth is 3m, and concrete hard slope protection is adopted, with a slope ratio of 1:2.5; the structure of the greenhouse is a concrete ring beam foundation, a full-frame steel frame, the main frame is composed of Φ100mm and Φ75mm galvanized pipes, and Φ4.2mm 7-strand steel wires are used for the shed surface. Covered with 12 silk polyvinyl chloride plastic film, the greenhouse pool is east-west, and there are 2 young shrimp breeding ponds in the middle. There are 2 greenhouse breeding ponds on both sides of the young shrimp breedi...

Embodiment 2

[0045] The cultivation system of Example 1 was used.

[0046] Breeding method:

[0047] (1) Establish the above-mentioned high-yield culture system of Penaeus vannamei;

[0048] (2) Use photosynthetic bacteria and lactic acid bacteria to improve water quality, each with 8 kg / mu, once every 18 days;

[0049] (3) put into the young shrimp of specification 3.5cm in the greenhouse culture pond, density 280,000 / mu;

[0050] (4) Feeding with an automatic cruising bait feeding machine, feeding is 4 times / day, and the feeding time is 5:00, 12:00, 18:00, 23:00, and the feeding amount is adjusted according to the feeding situation of the bait table ;

[0051] (5) After 65 days of young shrimp breeding, grow Penaeus vannamei with a size of 90 heads / kg.

[0052] The Penaeus vannamei cultivated in this example is cultured four times a year, and the annual output of Penaeus vannamei is 5000 kg / mu.

Embodiment 3

[0054] The cultivation system of Example 1 was used.

[0055] Breeding method:

[0056] (1) Establish the above-mentioned high-yield culture system of Penaeus vannamei;

[0057] (2) Use photosynthetic bacteria and lactic acid bacteria to improve water quality, each with 5 kg / mu, once every 15 days;

[0058] (3) put into the young shrimp of specification 3.0cm in the greenhouse culture pond, density 250,000 / mu;

[0059] (4) Feeding with an automatic cruising bait feeding machine, feeding is 4 times / day, and the feeding time is 5:00, 12:00, 18:00, 23:00, and the feeding amount is adjusted according to the feeding situation of the bait table ;

[0060] (5) After 60 days of breeding of young shrimp, vannamei with a specification of 100 heads / kg was grown.

[0061] The Penaeus vannamei cultivated in this example is cultured four times a year, and the annual output of Penaeus vannamei is 4500 kg / mu.

Abstract

The invention discloses a penaeus vannamei high-yield cultivation system which comprises greenhouse ponds, a water circulation system and blow-down systems, wherein the blow-down systems are positioned at the bottoms of the greenhouse ponds; the greenhouse ponds comprise a greenhouse breeding pond and a young shrimp breeding pond; the water circulation system comprises a water ecology regulation pond, the greenhouse breeding pond and a wastewater treatment pond; the water ecology regulation pond communicates with the greenhouse breeding pond; the wastewater treatment pond communicates with the blow-down system; the water ecology regulation pond and the wastewater treatment pond are all arranged outside the greenhouse pond; a comprehensive oxygenation system and an automatic cruise feeding machine are further arranged inside the greenhouse pond. The invention further discloses a breeding method for the penaeus vannamei high-yield cultivation system. According to the breeding method, young shrimps of 3.0-4.0cm are adopted as shrimp larvae for breeding. By adopting the penaeus vannamei high-yield cultivation system and the breeding method disclosed by the invention, the breeding rotations can be increased, four rotations of shrimps can be bred, the yield can be high, aquatic products can sold in the market in balance in four seasons, and the market supply can be increased.

Description

technical field [0001] The invention relates to a culture technique of Penaeus vannamei, in particular to a high-yield culture system and a culture method of Penaeus vannamei. Background technique [0002] Vannamei white shrimp (Penaeus vannamei), commonly known as white limb shrimp, white shrimp, was once translated as vannamei shrimp. Penaeus vannamei is one of the three largest shrimp species with the highest aquaculture production in the world today. Penaeus vannamei is native to the Pacific coast of South America, and has been promoted and cultivated in various parts of my country. The meat of Penaeus vannamei is delicious, and the processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18°C-32°C. It also has a wide salt range and can grow at a salinity of 1-40. It is an excellent desalinated cultured species. It has gradually become the main cultured shrimp species in southern my country. In recent years, due to the aging of ponds...
