Research Progress of Grass Carp Reovirus

Abstract

Grass Carp Reovirus(GCRV), also called Grass Carp Hemorrhagic Disease Virus, is the first fish virus isolated in China. Grass carp hemorrhagic disease caused by GCRV is a highly infectious and pathogenic fish disease. It has the characteristics of wide epidemic range, long onset season, high morbidity and mortality. However, its frequent outbreak has affected the development of aquaculture industry in China and caused huge economic losses to freshwater fisheries. Therefore, it is imperative to study the theory of grass carp reovirus.

This paper mainly reviews the biological characteristics, pathogenic mechanism and vaccine of GCRV, aiming at summarizing the relevant theoretical basis and understanding the new technologies and methods related to GCRV vaccine. To provide a strong and powerful theoretical reference for the prevention of the virus disease and development of green fisheries.
