Abstract

White shrimps have a important economic value for pond fishery in Kendal Regency. Problem that often occurred, which prevents the fishery harvest, related to WSSV (White Spot Syndrome Virus) and TSV (Taura Syndrome Virus). Such phenomenon led an idea to a study on the incidence of WSSV and TSV viruses in White shrimps (Litopenaeus vannamei). In case of this study, objects to be examined were intensive, semi-intensive, and traditional ponds located in Kendal Regency. This study aimed to find out the incidence of WSSV and TSV exposures to the shrimp ponds in Kendal that applied intensive, semi-intensive, and traditional technologies. Using a PCR test and histopathology examination on the White shrimps (Litopenaeus vannamei), the study was carried out from June to September 2009. The study used was a survey method, in which samples were obtained by means of a purposive random sampling. Objects of the sampling consisted of intensive (T1), semi-intensive (T2), and traditional (T3) ponds. These shrimp samples were then subject to a PCR test at BBAP Jepara to investigate exposures or incidents of the WSSV and TSV in the sample animals. The PCR analysis was done descriptively. Results of the study showed that the WSSV-generated disease in the White shrimps (L. vannamei) was still found at the T3 (traditional) ponds. It was also shown that at the TSV-generated disease occurred at both T1 (intensive) and T2 (semi-intensive) ponds. Meanwhile, the PCR test assumed that 30 day-old shrimps at the T1, T2, and T3 ponds were resistant to the TSV-generated disease. However, an observation at the T3 ponds detected WSSV viruses. In addition, this study also reported that ponds with intensive and semi-intensive technologies have good biosecurity system to minimize the incidents of WSSV and TSV in White shrimps (Litopenaeus vannamei). Keywords: Incidence, WSSV, TSV, Clinical Sign, PCR, White shrimps.
