Electron micrograph of virion and structure of white bream virus
Virus classification
(unranked):	Virus
Realm:	Riboviria
Kingdom:	Orthornavirae
Phylum:	Pisuviricota
Class:	Pisoniviricetes
Order:	Nidovirales
Family:	Tobaniviridae
Subfamily:	Piscanivirinae

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.

The subfamily is hitherto bigeneric with the 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.

The name is a siglum typical for virus taxonomy which here supposedly refers to the host animals fishes (Latin pisces), the host species Blicca bjoerkna of the virus species White bream virus, and the overarching order of the nidoviruses.

Taxonomy

The subfamily contains the following genera, subgenera, and species:

• Bafinivirus
  • Blicbavirus
    • White bream virus
  • Pimfabavirus
    • Fathead minnow nidovirus 1
• Oncotshavirus
  • Salnivirus
    • Chinook salmon nidovirus 1
