High-survival-rate penaeus vannamei aquaculture method

Abstract

The invention discloses a high-survival-rate penaeus vannamei aquaculture method. The method comprises the following steps that 1, the pH value and transparency of aquaculture pond water are controlled, and a contamination draining mechanism and a water circulating mechanism are arranged in an aquaculture pond; 2, shrimp larvae are put in a shallow water zone; 3, a recuperating agent and feedstuff for a mouth-open period are evenly mixed, feeding is performed by adopting a first feeding method, an activator is put in the afternoon every day, and shrimp shell caring liquid is put in the aquaculture pond in the morning and afternoon every day; 4, feeding of the feedstuff for the mouth-open period is stopped, a juvenile shrimp feed is fed and is fed by adopting a second feeding method, and the shrimp shell caring liquid is put in the aquaculture pond in the morning and afternoon every three days; 5, the feeding of the juvenile shrimp feed is stopped, a middle-sized shrimp feed is adopted for feeding and is fed by adopting a third feeding method, and the shrimp shell caring liquid is put in the aquaculture pond in the morning and afternoon every seven days. The high-survival-rate penaeus vannamei aquaculture method has the advantages of remarkably improving the survival rate and acre yield of penaeus vannameis, reducing feed coefficients and improving the growth speed of the penaeus vannameis.

Description

technical field [0001] The invention relates to the field of culture of Penaeus vannamei. More specifically, the present invention relates to a culture method of Penaeus vannamei with high survival rate. Background technique [0002] Penaeus vannamei, whose scientific name is Penaeus vannamei, belongs to the phylum Arthropoda. It is a wide-temperature and wide-halt tropical shrimp. It looks exactly like Penaeus sinensis and Penaeus megi. Its average life span can exceed 32 months. Thin, the normal body color is light blue-gray, the whole body has no markings, and the legs are often chalky, so it is called white-limbed shrimp. The meat is delicious and has high economic value. [0003] At present, Guangdong, Guangxi, Fujian, Hainan, Zhejiang, Shandong, Hebei and other provinces or autonomous regions have gradually promoted farming. The vannamei cultured in Yangjiabo Town, Hangu District, Tianjin is world-famous and has the reputation of "the hometown of fish and shrimp in Ch...

Problems solved by technology

[0005] However, since 2002, as the breeding environment has continued to deteriorate, the quality of seedlings has deteriorated and other factors have led to a large-scale outbreak of white spot virus in prawns, which has seriously damaged the aquaculture industry of Penaeus vannamei.

The disease has become the most serious restricting factor for sea and freshwater aquaculture Penaeus vannamei at present. Once the disease is not treated in time and effectively, the prawns will appear to climb and die, which will seriously lead to the loss of production in the whole pond and the annihilation of the whole army. The majority of farmers have caused heavy losses, and at present there are no good and active control measures for diseases, which reduces the overall survival rate of breeding. Therefore, it is urgent to develop an effective and active disease-resistant breeding method
