High-density culture method for litopenaeus stylirostris

Abstract

Provided is a high-density culture method for litopenaeus stylirostris. The high-density culture method comprises following steps: 1, selecting each pond having sand content, 3 to 10 mu in an area and 1.8 to 2.5m in water depth, equipped with water-feeding and water-drainage facilities in absence of pollution, 2, cleaning and disinfecting the pond prior to free culture; 3, selecting and freely culturing stylirostris seeds, particularly selecting strong, non-injurious and virus-free seeds; 4, feeding seeds with feedstuff in accordance with three phases including feeding in small amount at an early phase, feeding artificial compound feed every day at a medium phase of cultivation and feeding fresh baits at a late phase of cultivation; 5, preventing and curing diseases and splashing lime water regularly; 6, performing daily management such as regular monitoring physical, chemical factors and biological factors of water in the culture pond and bottom material and paying attention to regular water-drainage and water-renewing. By taking the above culture method, high-density artificial feeding in the finite pond and high-quality litopenaeus stylirostris is cultured so that the requirement of the market is satisfied.

Description

technical field [0001] The invention relates to a high-density pond culture method of Penaeus vannamei and belongs to the technical field of agricultural culture. Background technique [0002] South American blue prawn (Litopenaeus stylirostris) belongs to Arthropoda, Crustacea, Decapod, Swimming suborder, Penaeidae, Penaeus genus, Litopenaeus subgenus, is a euryhalal tropical shrimp species, native to the Pacific coast of Latin America. It can be cultured throughout the year in the original place, and it is mostly mixed with white shrimp, and has the advantages of fast growth, low bait cost, wide range of temperature and salt tolerance, low dissolved oxygen resistance, strong disease resistance, and high meat yield. With the continuous improvement of Penaeus vannamei breeding technology and the acquisition of SPF shrimp seedlings, artificial breeding has been gradually promoted. my country began to introduce and promote breeding after 2000, and achieved success in artificia...

AI Technical Summary

Problems solved by technology

With the improvement of people's living standards, the market demand for Penaeus vannamei is increasing, and the corresponding breeding scale is also increasing. The expansion of the breeding scale is not only to expand the area of ​​the breeding pond, but also to increase the breeding density. Density farming leads to a series of problems, the most important is the increase of diseased and dead shrimps, which increases the potential risk
