Method for culturing indoor industrialized ecological specific-pathogen-free juvenile litopenaeus vannamei

Abstract

The invention belongs to the field of culture of aquatic animals, and particularly relates to a method for culturing indoor industrialized ecological specific-pathogen-free juvenile litopenaeus vannamei. The method comprises the following steps: (1) culture seawater treatment; (2) cleaning and disinfecting of an indoor culture pool; (3) throwing of nauplii without specific pathogens; (4) preparation and feeding of specific-pathogen-free baits; (5) control of key nodes in a culture process; (6) detecting and tracking of the whole culture process; (7) specific-pathogen-free detection and qualityinspection of juvenile shrimps; and (8) selling of the juvenile shrimps. According to the method for culturing the juvenile litopenaeus vannamei, an ecological culture concept is adopted, a basic principle of natural life propagation of the litopenaeus vannamei is followed, an artificial algae phase and a natural hyphae phase of the pool are constructed, drug banned substances and antibiotics areforbidden in the whole process, the culture survival rate of the litopenaeus vannamei can be increased remarkably, the average survival rate can achieve 75% or above, and it can be ensured that the cultured juvenile shrimps are specific-pathogen-free (SPF), and are full in intestinal tract and good in appetite.

Description

technical field [0001] The invention belongs to the field of aquatic animal breeding, in particular to a method for cultivating Litopenaeus vannamei in an indoor industrialized ecological style without specific pathogens. Background technique [0002] In recent years, my country's prawn farming industry has developed rapidly. At the same time, various factors such as the deterioration of the aquaculture environment and the uneven seed quality have dealt a heavy blow to the entire prawn aquaculture industry. The production of shrimp seed, the basis of the shrimp farming industry, is gaining in importance. In the 21st century, the farming trend in the shrimp farming industry has shifted from one-sided pursuit of speed to high-quality production. The cultivation of high-quality seed has attracted great attention from the government, enterprises, and farmers. People's demand and awareness of high-quality seed have reached Unprecedented heights. The quality of prawn fry directly...

Problems solved by technology

[0005] Check out some domestic enterprises, institutions and individuals who have applied for patents related to Litopenaeus vannamei seedlings. For example, Hu Zhuangtao et al. invented and disclosed a method for ecologically cultivating Penaeus vannamei seedlings (application number: 201610898563.6). Cultivate bait organisms such as unicellular algae, rotifers, cladocera, scleropoda, etc., put Penaeus vannamei nauplii in the outdoor big pond (high level pond), and cultivate shrimp seedlings with abundant bait organisms , this method mainly raises Penaeus vannamei seedlings outdoors, which is similar to the ecological seedling method of Litopenaeus vannamei in outdoor water (application number: 201510068607.8), an invention patent authorized by our unit; Cui Zhaoxia et al. invented and disclosed a vannamei The seedling raising method of Litopenaeus vannamei (application number: 200810015938.5), put Litopenaeus vannamei nauplii into the nursery pond, and simultaneously cultivate rotifers to feed Litopenaeus vannamei nauplii, wherein the density of Litopenaeus vannamei nauplii is 1 ten thousand tails / m 2 , and add shrimp chips, soy milk and yeast artificial bait, the density of the nauplii in this method is too low, and it is not suitable for industrialized and large-scale seedling breeding needs; Guangdong Hengxing Group Co., Ltd. Shrimp seedling method in small water (application number: 201410076358.2), this method is applicable to 1m 3 It is carried out in the circular aquariums on the left and right, and only belongs to the small water sports seedling method; Maoming Jinyang Tropical Haizhen Breeding Co., Ltd. discloses a kind of industrialized ecological seedling method of high-strength stress resistance and disease resistance shrimp seedlings (application number : 201510338222.9), through the biological regulation of the water quality environment of the indoor seedling pond and the effective control of water temperature, light, transparency, dissolved oxygen, salinity, PH value, harmful substances and disease organisms, etc., optimize the environmental conditions of seedling cultivation, reduce medication and reduce feeding and reduce drainage; enhance the stress resistance and disease resistance of shrimp seedlings, improve the quality and survival rate of shrimp seedlings, this method lacks the detection tracking and quality evaluation in the process of shrimp seedling cultivation, and is very important for the real cultivation of shrimp seedlings without specific pathogens (SPF). there are still some risks

Although the above-mentioned relevant patents and relevant documents have tried various methods and models for the seedling cultivation of Litopenaeus vannamei, there is little reference to the method for cultivating shrimp seedlings without specific pathogens (SPF)
