(Fenneropenaeus indicus) study on protozoa emerging diseases of shrimp

Certain diseases such as bacterial , viruses, parasirtic ones Protozoa parasites Could severe mortalities in farmed shrimp last decades. Two hundred and seventy Fenneropenaeus indicus with the weight of 10± 1.09 were selected, transferred to Iran Shrimp Center and distributed to the treatmentsand controls (3 groups). The objective of our study was to describe the signs, prevalence, and intensity of Hemocytosis, a new disease in shrimp, Fenneropenaeus indicus. The experimental design included three groups, one treatment as infected shrimp or group B and 2 controls with non-infected but exposure to White Spot Syndrom Virus (WSSV) shrimp as group A and non-infected non- exposure to WSSV shrimp as group C in triplicate. The results revealed that Hemocytosis associated with a decrease in hyalinocytes and large-granulocytes (less than 8%) and a considerable increase in semi-granulocytes in group A and B in contrast to group C that Hyalinocyte increased. This infection made the shrimp susceptible to WSSV disease. It is believed that Hemocytosis causes a condition which can result in a rapid mortality among susceptible species, F. indicus when exposure to WSSV is occurred.
