| Abstract | ||
| One of the most important causes of shrimp diseases in wild environment and Farms are Parasitic disease and Gregarines are the reutine parasites in shrimp. This study was conducted in Khouzestan Province to determine the prevalence and intensity of Gregarine parasites in Kiddi shrimp (Prapenaeopsis stylifera), a natural species of Persian Gulf, and Pacific white shrimp (Litopenaeus vannamei), currently the major cultured species in Iran. Shrimps were randomly collected from Persian Gulf and Choebde shrimp farms in Abadan, Digestive tracts of the shrimps were studied using wet-mount diagnostic procedure. In this study no Gregarine parasites were observed in Pacific white shrimp whereas infection rate among Kiddi shrimp was 32.5% including Genera: Nematopsis, Rotundula, Heliospora and other unknown Gregarine parasites. The highest infection rate belonged to Genus Nematopsis(%9.55). According to the published materials available, this is the first report of Kiddi shrimp being parasitized with Gregarine parasites. Also the relationship between shrimp body length and the rate of infection was found to be positive. But there was no meaningful relationship between sex and the rate of infection. | ||
