Piscanivirinae is a virus subfamily of the family Tobaniviridae within the order Nidovirales which comprises different fish viruses. The virions have a viral envelope and a positive-sense single-stranded RNA genome which is linear and unsegmented.

Virus classification  | |
| (unranked): | Virus |
| Realm: | Riboviria |
| Kingdom: | Orthornavirae |
| Phylum: | Pisuviricota |
| Class: | Pisoniviricetes |
| Order: | Nidovirales |
| Family: | Tobaniviridae |
| Subfamily: | Piscanivirinae |
The subfamily contains two genera: Bafinivirus and Oncotshavirus. Both genera comprise rod shaped (bacilliform) viruses with relatively large genoms like they mostly occur in the nidoviruses. Occasionally, also strongly pleomorphic (e. g. spheric) virions were observed.[1][2]
Taxonomy
editThe subfamily contains the following genera, subgenera, and species:[3]
- Bafinivirus
- Blicbavirus
- Bafinivirus bliccae (White bream virus)
- Pimfabavirus
- Bafinivirus pimephalae
- Blicbavirus
- Oncotshavirus
- Salnivirus
- Oncotshavirus oncorhynchi
- Salnivirus
