Aquareovirus is a genus of double-stranded RNA viruses in the order Reovirales and family Spinareoviridae. Fish, shellfish, and crustacean species serve as natural hosts. Aquareoviruses in general have low or no pathogenicity for fish. However, some cause hemorrhagic disease, hepatitis and pancreatitis. Grass carp hemorrhage virus (causes hemorrhagic disease of grass carp) is the most pathogenic aquareovirus. There are seven species in this genus.
