2005~2009年凡纳滨对虾白斑综合征和桃拉综合征的流行情况分析

Prevalence study on Penaeus vannamei infected with WSD and TS during 2005~2009

摘要: 文章概述了中国2005~2009年凡纳滨对虾(Penaeus vannamei)白斑综合征(WSD)和桃拉综合征(TS)的发病特点及流行情况，分析了2种病毒病发生的原因，并提出了防治措施。分析表明, 凡纳滨对虾感染白斑综合征病毒(WSSV)和桃粒综合征病毒(TSV)后，TS的发病率为9.22%~12.39%，死亡率12.74%~24.74%;WSD的发病率为4.50%~9.12%，死亡率10.62%~18.95%。TSD的发病率高于WSD，死亡率除2007年外也高于WSD。

Abstract: We summarized the characteristics and prevalence of Penaeus vannamei infected with white spot disease(WSD) and Taura syndrome (TS) during 2005~2009 to study the causes and prevention of the diseases. Results show that the incidence rate of TS and WSD is 9.22%~12.39% and 4.50%~9.12%, respectively; the mortality of TS and WSD is 12.74%~24.74% and 10.62%~18.95%, respectively. The incidence rate of TS is higher than that of WSSV, and the mortality of TSV is also higher than that of WSD except for 2007.
