凡纳滨对虾混养技术研究进展

Research Progress on Mixed Culture of Litopenaeus Vannamei

简述了凡纳滨对虾混养模式和主要混养品种,分析了凡纳滨对虾混养密度对养殖产量和经济效益的影响。指出,凡纳滨对虾混养,合理利用了池塘空间和饵料,改善了水质底质,可防控病害,提高产量,增加养殖经济效益。提出,今后凡纳滨对虾混养可采用新技术,如碳氮比调控技术,充分利用富余营养元素,促进微生物的繁殖,从而维持池塘的稳定性,提高生产能力;试验混养新品种;探究混养防控病害的机理,为凡纳滨对虾产业健康可持续发展提供理论指导。

The mixed culture model and main mixed culture varieties of Litopenaeus vannamei were briefly introduced, and the effects of mixed culture density on the yield and economic benefits of Litopenaeus vannamei were analyzed. It is pointed out that the mixed culture of Litopenaeus vannamei can rationally utilize the pond space and bait, improve the water quality and bottom quality, prevent and control the disease, increase the yield,and increase the economic benefit of breeding. It was suggested that new technologies, such as the regulation of carbon nitrogen ratio, could be adopted in the future to make full use of the excess nutrients and promote the reproduction of microorganisms, so as to maintain the stability of the pond and improve the productivity of the pond. Test new hybrid varieties;To explore the mechanism of disease prevention and control of mixed culture,and provide theoretical guidance for the healthy and sustainable development of Litopenaeus vannamei industry.
