Ictalurid herpesvirus 2 (IcHV-2) is a species of virus in the genus
Also known as the black bullhead virus, it is
Background
Ictalurid herpesvirus 2 was first observed in 1994 after two mass mortality events occurred in two different catfish farms in Italy, resulting in severe economic loss.[3]
As observed in experimental trials, there is a higher mortality rate in channel catfish when exposed to IcHV2 than in trials and previous background studies where channel catfish were exposed to IcHV1.[2] It is also shown that through syncytial cytopathic effect, both strains of Ictalurid herpesvirus are homologous to the syncytia produced.[3]

Pathology
Clinical signs of IcHV2 include disoriented swimming or instances where they dwell at the surface of the pond bank.
IcHV2 propagation control is a highly researched topic due to it showing much more intensive mortality rates in channel catfish than IcHV1. The high mortality rate is due to the fact that IcHV2 propagation and viral transmission has an optimal temperature of 24oC, which is relatively lower than IcHV1.[4] Furthermore, overcrowded pens contribute to the transmission of the virus.
