The program was conducted by collecting samples from shrimp farms and diagnosed using commercially available viral kits by polymerase chain reaction PCR method. In year 2006 only one shrimp farm shows the presence of white spot syndrome virus WSSV in culturing P. monodon. However no viral diseases were detected in the survey carried out in the year 2007. The Sampling done recently early 2008 shows the presence of Taura syndrome virus TSV and WSSV in the same farm culturing of L. vannamei. Mitigation measures should be identified to reduce the risk associated due to pathogens introduction along with the movement of the cultured species. One od the most important measures is that all shipments of postlarvae to be imported should be of high health status and should originate from facility certified as using specific pathogen free SPF broodstock especially for L. vannamei.

Abstract

The lower market price or tiger shrimp has resulted in the introduction of the Pacific White Shrimp Litopenaeus in Sarawak. Presently about 70 of the shrimp farms have caused operation and the culturing of L. vannamei is attractive and expanding due to the high production and low operation cost. Disease survey program was carried out to document the occurrences of the major shrimp viral disease in Sarawak. The program was conducted by collecting samples from shrimp farms and diagnosed using commercially available viral kits by polymerase chain reaction PCR method. In year 2006 only one shrimp farm shows the presence of white spot syndrome virus WSSV in culturing P. monodon. However no viral diseases were detected in the survey carried out in the year 2007. The Sampling done recently early 2008 shows the presence of Taura syndrome virus TSV and WSSV in the same farm culturing of L. vannamei. Mitigation measures should be identified to reduce the risk associated due to pathogens introduction along with the movement of the cultured species. One od the most important measures is that all shipments of postlarvae to be imported should be of high health status and should originate from facility certified as using specific pathogen free SPF broodstock especially for L. vannamei.
