Aquareovirus is a genus of double-stranded RNA viruses in the family Reoviridae and subfamily Spinareovirinae.

Fish, shellfish, and crustacean species serve as natural hosts.

[1][2] Aquareoviruses are non-enveloped, with a double capsid structure that has icosahedral geometries, and T=13, T=2 symmetry.

The virus exits the host cell by monopartite non-tubule guided viral movement.

Fish, shellfish, and crustacean species serve as the natural host.
