Method for industrially and ecologically breeding litopenaeus vannamei shrimps in indoor space

Abstract

The invention discloses a method for industrially and ecologically breeding litopenaeus vannamei shrimps in indoor space. The method includes an industrially and ecologically indoor breeding process and a management method of the litopenaeus vannamei shrimps. According to the method, a traditional shrimp breeding technique is innovated, healthiest young litopenaeus vannamei is selected, the shrimps are stocked by the aid of the most reasonable density and fed by the aid of diatoms such as micro-thalassiosira rotula and chaetoceros mulleri and high-quality natural organism baits such as fairy shrimp nauplii, part of artificial feed and baits are replaced, nutrition can be enhanced, immunity can be improved, water quality change of a shrimp pond can be effectively controlled, self-cleaning capacity of water is enhanced, growth of harmful bacteria is restrained by the aid of beneficial bacteria such as lactic acid bacteria, bacillus and pseudomonades, residual feed, shrimp remains and thelike are decomposed, and a stable ecological system of the shrimp breeding pond is built. According to the method, healthy, rapidly-grown, high-stress-resistant and high-quality shrimps can be bred,shrimp breeding survive rate can be increased, shrimp breeding cost is saved, and the shrimp quantity requirements of clients are met, so that economic benefits are improved.

Description

technical field [0001] The invention belongs to the field of aquaculture, and relates to a method for cultivating young Penaeus vannamei, in particular to a method for indoor factory ecological cultivation of young Penaeus vannamei. Background technique [0002] In recent years, my country's shrimp farming industry has developed rapidly. China's shrimp farming production accounts for about 1 / 3 of the world, ranking first in the world. Penaeus vannamei is the largest shrimp farming species in China; the current annual demand for shrimp fry in China About 500 billion tails, while the shrimp juveniles of Penaeus vannamei are about 440 billion tails. Since 1992, the outbreak of various viral diseases and bacterial diseases has brought a serious blow to the development of the world's shrimp industry. [0003] At present, the traditional production of Penaeus vannamei in China is a single indoor cement pond mode. The traditional breeding method uses exogenous artificial bait and h...

Problems solved by technology

[0003] At present, the traditional production of Penaeus vannamei in China is a single indoor cement pond mode. The traditional breeding method uses exogenous artificial bait and high-density breeding. Consumption of bottom, resulting in low survival rate

The nutrition of artificial bait is not as high as that of fresh biological bait, and the nutrition can not keep up with it, which leads to delayed expression and slow growth

The high organic content of residual bait, shrimp fry metabolism, and larvae remains leads to the growth and rapid reproduction of bacteria and germs in the seedling pond, which causes various symptoms. In order to control the outbreak of the disease, a large amount of antibiotics are often used, and then In addition, the quality of seedlings on the market is uneven, and serious problems such as carrying viruses and slow growth are emerging one after another.

Leading to a large amount of bait costs, high cost of antibiotics, poor quality of shrimp seedlings, and low breeding benefits. Such seedlings can no longer meet the needs of farmers
