Method for improving quality of penaeus vannamei boone of desalination cultivation

Abstract

The invention belongs to the aquaculture field, in particular relating to a method for improving the quality of desalination-cultured Litopenaeus vannamei, i.e. Penaeus vannamei. The method comprises desalination domestication and artificial commercial feedstuff aquatic breeding, and concentrates on transferring Litopenaeus vannamei, which is bred in a water body with the salinity equal to 2 per mill and has a biological body length equal to 10.0+ / -0.5cm, to a water body with the salinity equal to 5 per mill so as to be bred temporarily for 7 days before selling on the market; and the Litopenaeus vannamei is bred and managed by means of general commercial prawn feedstuff. Compared with the prior art, the method can substantially increase the meat content, the total amount of muscle crude protein, crude fat and tasty amino acid and the content of polyunsaturated fatty acid of Litopenaeus vannamei; meanwhile, the method can obviously increase the nutritive value, the edible quality and the flavor of Litopenaeus vannamei. Moreover, the method does not causes any adverse effect on the survival of Litopenaeus vannamei, and has convenient technical popularity, short cycle, no toxic sideeffect, no pollution and low cost.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for improving the quality of desalinated cultured Litopenaeus vannamei. Background technique [0002] Litopenaeus vannamei (Litopenaeus vannamei), namely Penaeus vannamei, also known as Penaeus vannamei. Litopenaeus vannamei, Penaeus monodon, and Penaeus sinensis are listed as the top three high-quality shrimp species with the highest aquaculture production in the world. Litopenaeus vannamei is native to the Pacific coast of the Americas from Mexico to Peru. In the early 1970s, the artificial culture of Litopenaeus vannamei was the first to be successful in Ecuador. In 1987, my country introduced the shrimp for transplantation experiments and achieved success. Because the shrimp has rapid growth, high meat yield, low demand for feed protein, long out-of-water survival time, strong disease resistance, suitable for high-density farming and strong toleranc...
