TWENTY-SECOND ANNUAL EASTERN FISH HEALTH WORKSHOP ROYAL PAVILLION RESORT, ATLANTIC BEACH, NC MARCH 18 - 20, 1997 Potential Shrimp Virus Impacts on United States Wild Shrimp Populations, an Overview. Frederick G. Kern National Marine Fisheries Service, Cooperative Oxford Laboratory, Oxford, MD 21654 Recent reports of new, highly virulent shrimp diseases have raised concerns of their impact on United States marine resources. Four viruses, Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV), Taura Syndrome Virus (TSV), White Spot Syndrome Virus (WSSV), and Yellow Head Virus (YHV) have recently been documented to be highly virulent to United States native shrimp. There is some documented evidence that IHHNV caused a decline in the Gulf of California shrimp fishery to levels that could not support a commercial harvest. This report will review the status of these four shrimp viruses. Their impact on shrimp culture and natural shrimp populations throughout the world, and recent suspected outbreaks in the United States.
