가리비의 Acute Viral Necrosis Virus (AVNV) 모니터링

Abstract

Among the Pectinidae occurring in the Republic of Korea, the industrially important species are Patinopecten yessoensis, Chlamys farreri, and Argopecten irradians. In Korea, mass mortality of farmed scallops has occurred in spring and summer during periods of elevated water temperature, although the cause of scallop mortality has not been clearly identified. Since the mid-1990s, acute viral necrosis virus (AVNV) has caused mass mortality in C. farreri in China with a known mortality rate of 90%. Till date, acute viral necrosis disease (AVND) has been reported only in China and is not listed as an aquatic disease by the Office International des Epizooties. AVND is not a communicable disease of aquatic organisms that has been designated and controlled by the Korean "Aquatic Life Disease Control Act." There is a possibility of its inflow to Korea as there is no AVNV quarantine procedure for imported scallops. As AVNV was first detected in scallops imported to Korea in 2016, continuous monitoring is necessary. Therefore, we conducted AVNV monitoring of adult scallops, spat, and breeding water in domestic farms and spats imported from China; AVNV was not detected in any of the scallop or other samples. However, in case of an influx of AVNV to Korea in the future, it will likely lead to mass mortality of domestic scallops; therefore, continuous monitoring should be performed.
