Embodiment 1

[0028] In March 2016, in order to verify the beneficial effects of the present invention, a relevant verification test was done at the Aquaculture Center of Haitou Town, Lianyungang City, and the production and quality were measured after harvest. The obtained results are shown in Tables 2 and 3. The specific breeding method is as follows:

[0029]1. Shrimp pond selection and clear pond disinfection: In mid-March, select a square pond with a flat terrain, convenient transportation, fresh water, fresh and pollution-free sea water, and an area of ​​10 mu as a culture pond for Penaeus vannamei. The bottom of the pond is required to be muddy or The silt is the main type; before using the shrimp breeding pond, the water in the pond should be drained, then plowed and exposed to the sun for 10 days, and 65kg of quicklime should be applied per acre to disinfect the shrimp pond, and then it will be used for later use;

[0030] 2. Cultivate larvae bait: At the beginning of April, divert...

Embodiment 2

[0036] In March 2016, in order to illustrate the beneficial effects of incubation of Penaeus vannamei by the medium-wave magnetic interaction method of the route of the present invention, the staff did relevant comparative verification in the laboratory. The specific methods are as follows:

[0037] Treatment of the present invention: adopt the method step in step 3 in embodiment 1, cultivate 400 fertilized eggs of Penaeus vannamei, and count the success rate of hatching and hatching time after it hatches into nauplius, and the obtained results are shown in Table 1.

[0038] UV treatment alone: ​​except that the magnetized seawater in step 3 in Example 1 was replaced with ordinary seawater and no longer applied biological incubation solution, the same method steps were adopted to cultivate 400 fertilized eggs of Penaeus vannamei from the same source, and the After hatching into nauplii, the hatching success rate and hatching time were counted, and the results are shown in Table...

Embodiment 3

[0045] In March 2016, in order to illustrate the beneficial effect of raising bait and manure in the route of the present invention, the staff used the same method steps as in Example 1 to breed 33m 2 vannamei, yield and quality were measured after harvest, and the results are shown in Tables 2 and 3.

Abstract

The invention discloses a high-quality and high-yield breeding method for Penaeus vannamei, comprising the following steps: 1. shrimp pond selection and pond clearing and disinfection; 2. cultivationof larvae bait; 3, young shrimp incubation and cultivation; 4. intermediate shrimp culture; 5, young shrimp putting and feed management; 6, harvesting. The seed culturing water quality is improved byusing a magnetic wave interaction method to incubate the young shrimps, and the ammonia nitrogen content and the chemical oxygen demand in the water are reduced. The hatching rate of shrimp eggs and the survival rate of young shrimps, the growth of young shrimps is promoted, and the resilience is enhanced. By applying a biological hatching-inducing solution, the young shrimp physique is further improved, so that the shrimp body is robust. By applying a bait fertilizer, sufficient baits are provided in the water environment of the shrimp pond for feeding of young shrimps, which lays a foundation for increasing the yield and income of the Penaeus vannamei. By matching the feeds suitable for the growth and development of Penaeus vannamei in various growth periods, the nutritional needs of each period are fully satisfied, and the goal of high quality and high yield of Penaeus vannamei is finally achieved.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for high-quality and high-yield culture of Penaeus vannamei. Background technique [0002] Vannamei( Penaeus vannamei Boone ), the scientific name is Penaeus vannamei, which belongs to Arthropoda, Crustacea, Decapod, Penaeidae, and Penaeidae. The shape is very similar to that of Penaeus prawns, with an average lifespan of two and a half years. The length of the mature body of Penaeus vannamei can reach more than 20cm. Its carapace is thin. Penaeus vannamei, Penaeus sinensis, and Penaeus monodon are known as the world's three high-quality farmed prawns, and are one of the three most productive shrimps in the world today. It is native to the Pacific coast of South America. At present, there are large-scale breeding in Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Jiangsu, Hebei, Tianjin and other provinces and cities in China. [0003] Penaeus vannamei has high econ...
