Litopenaeus vannamei relay breeding mode

Abstract

The invention relates to a litopenaeus vannamei relay type breeding mode. For the litopenaeus vannamei relay type breeding mode, phased breeding management of specific pond desalination and standard size breeding, high-density fine breeding and timely accurate sparse breeding is conducted in a greenhouse pond, a transition pond and a breeding bond respectively, beneficial microorganisms are used for conducting directional adjustment and control on pond microbial ecology in the whole breeding process, a technology of catching and stocking in rotation is combined, and litopenaeus vannamei relay breeding in different spaces is achieved. The litopenaeus vannamei relay type breeding mode has the advantages that the pond utilization rate is high, two-batch litopenaeus vannamei larvae can be bred in one year, the time of juvenile litopenaeus vannamei staying in the breeding pond is short, the water quality and substrate are not prone to deterioration, after the juvenile litopenaeus vannamei is put into the breeding pond, the survival rate is high, precision of breeding management measures of feeding and the like is easy, the breeding water quality and microbial ecology are easy to control, the breeding yield is high, and the breeding benefit is high.

Description

technical field [0001] The invention relates to the technical field of shrimp culture, in particular to a relay culture mode of Litopenaeus vannamei. Background technique [0002] The origin of Litopenaeus vannamei is the Americas. It was introduced to my country from the United States by the Institute of Oceanography of the Chinese Academy of Sciences in July 1988. Now it has become the most widely cultivated shrimp species in my country with the largest aquaculture output. However, with the increase of aquaculture area and aquaculture density, the water environment in shrimp culture ponds tends to deteriorate, pathogens breed, and infectious diseases and stress diseases of shrimp are becoming more and more prominent. Very bad. Especially in the middle and late stages of aquaculture, with the extension of the pond culture time and the increase of the amount of feed, the aquaculture water and substrate often deteriorate, and the sudden change of weather can easily induce th...
