摘要
凡纳对虾(Litopenaeus vannamei)是全球三大养殖对虾名优种类之一。我国从1988年开始试养,到1998年大量引进凡纳对虾亲虾和幼体后,华南地区兴起了养殖热潮。在1999年到2000年短短两年时间内,广东、海南、广西凡纳对虾的养殖面积已达10×10~4亩(1亩=666.7m^2),集约化防病养殖产量普遍达到5~9t/hm^2,年产量高达10~20t/
The genome of Litopenaeus vannamei was analyzed by random amplified polymorphic DNA (RAPD) analysis to identify DNA markers for important traits in Litopenaeus vannamei in the South China. A total of 20 ten-bases primers were screened, and eight positive primers giving highly reproducible RAPD patterns were selected for comparison between healthy and diseased populations of Litopenaeus vannamei. A total of 38 reproducible RAPD fragments ranging from 200 to 1750 base pairs were scored, and 24 fragments (62.2% ) were polymorphic. Only three RAPD markers, OPX - 01 - 1020, OPX - 14 - 530 and OPX - 17 - 940, were found in the diseased population of Litopenaeus vannamei , suggesting the potential use of them as DNA markers for helping broodstock management and selection for breeding.
