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

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 of TS and WSD is 9.22%~12.39% and 4.50%~9.12%, respectively; the mortality rate of TSV and WSDis 12.74%~24.74% and 10.62%~18.95%, respectively. The incidence of TS is higher than that of WSD, and the mortality rate of TSV is also higher than that of WSD except for 2007.
