为了解广西沿海地区南美白对虾白斑综合症病毒(WSSV)的感染情况,本文采用野外采样和PCR检测方法调查钦州市、钦南区、港口区、防城区、东兴市、北海市、铁山港区和合浦县等8个监测区的南美白对虾WSSV感染情况。2013年共检测南美白对虾样本317份,WSSV总阳性率为19.6%。其中,虾苗和成虾的WSSV阳性率分别为1.5%和32.1%。在8个监测区中,北海市虾苗和成虾WSSV检出率均为最高,分别为5.6%和76.5%。总体上,2013年WSSV在广西沿海地区除铁山港外的南美白对虾养殖区均有不同程度的流行,且成虾平均阳性率高于虾苗。
In order to understand the infection status of WSSV in coastal areas of Guangxi, this paper investigated Qinzhou, Qinan, Port Area, Fangcheng District, Dongxing City, Beihai City and Tieshangang Port by field sampling and PCR detection methods WSSV infection of Penaeus vannamei in eight monitoring areas such as Hepu County and Hepu County. In 2013, 317 samples of P. vannamei were detected, and the total positive rate of WSSV was 19.6%. Among them, the WSSV positive rates of shrimp and shrimp were 1.5% and 32.1% respectively. Among the eight monitoring areas, the detection rates of WSSV in shrimp and adult shrimp in Beihai were the highest, 5.6% and 76.5% respectively. Overall, in 2013, WSSV prevailed in varying degrees in white shrimp farming areas outside Guangxi Tientsin except Tieshan Port, and the average positive rate of adult shrimp was higher than that of shrimp.
