Description:
After severe mortality due to white spot disease incidence in cultured shrimps of Helleh grows out farms, disease
spread to Delvar,Mond, Boeyrat and Bandar Rig sites in Bushehr province during 2005. Many crustaceans keep
this virus in the body, act as a carrier, and can spread of the infection.
In order to investigate status of contamination of wild shrimp and crab's population to white spot virus in
Bushehr province waters (north of Persian Gulf), samples were collected and tested by Nested PCR for detection
of WSV from estuaries and input and output channels water around the Helleh, Shif and Mond sites during
2007 and 2008. Total tested shrimps were 401 peaces, includes green tiger shrimp (Penaeus semisulcatus) 220
pieces, white shrimp (Metapenaeus affinis) 181 pieces, also total tested crabs were 292 pieces includes Ocypode
rotundata 68 pieces and Portunus pelagicus 224 pieces. All the samples showed negative results of WSV contamination. However, it can never be sure that the
population is free from WSV unless we collect a random sample of 300 pieces from each species and test them
individually for WSV. Therefore, we will be confident up to 95% that the wild sources in that area have no
prevalence of 1% or upper WSV contamination.
