Method for efficiently breeding South American white shrimps

Abstract

The invention provides a method for efficiently breeding South American white shrimps. The method comprises the following steps that firstly, at the desalination stage, shrimp fry conveyed from Haian Province are conveyed to a mud pool to be desalinated for 7-8 days, the temperature is controlled between 17 DEG C and 35 DEG C, the aeration is carried out through aerators for 2.5-4.5 hours, at the moment, bittern is poured into the mud pool, and the salinity of the mud pool is desalinated by using fresh water every day, wherein the length of the white shrimps ranges from 5 centimeters to 6 centimeters; secondly, at the breeding stage, the shrimp fry are placed in a pond with the area ranging from 8 mu to 15 mu to be bred for 3 months, the stocking density of the shrimp fry ranges from 120 thousand fry per mu from 15 thousand dry per mu, the transparency of the pond ranges from 20 centimeters to 30 centimeters, the pH ranges from 7.9 to 8.3, the two or three aerators are used for aerating, and feeding fodder is added in the process of breeding and is mixed with vitamins and probiotics promoting substances. The method has the advantages that the rate of survival of the South America white shrimps and the nutritive value of the white shrimps are improved, the growth of an effective microbial community in a water body is promoted, the improvement of the water quality is promoted, and eutrophication caused by unnecessary fodder is avoided.

Description

technical field [0001] The invention belongs to the field of culture technology of Penaeus vannamei, and in particular relates to a high-efficiency culture method of Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three largest shrimp species with the highest aquaculture production in the world today. Penaeus vannamei is native to the Pacific coast of South America. The meat of Penaeus vannamei is delicious. The processed meat rate can be as high as 67%. It has a wide temperature range and is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the main cultured shrimp species in southern my country, which is conducive to increasing the income of sea people. [0003] At present, the breeding technology of Penaeus vannamei is becoming more and more mature, but the survival rate of Penaeus vannamei is not very high. At the same time, the feed that is fed causes eutrophi...
