Survey on white spot disease in wild Penaeus indicus in Hormozgan coastal waters of Iran

More than 20 viruses have been reported as pathogens to shrimp. WSSV has been found to be highly pathogenic not only to penaeid shrimp، but also to a wide host range which include marine crabs and copepods،freshwater crabs and prawns. This survey carried out to detect the WSV in wild P. indicus population on the costal waters of Hormozgan Province. The samples were collected from three area include: costal waters of Qeshm island، Hormoz island and Jask. We examined 1080 P. indicus (gill organs) by PCR and histopathology methods. A diagnostic kit for this survey have been applicated from Malaysia،named”Single-Tube Nested PCR for WSSV”. The analysis results revealed that the samples of P. indicus had examined from these area were free from WSV. The PCR tests were negative for all samples and no observed any damages of histology due to WSSV on gills.
