Major disease threats to carp industry l.jpg
Major Disease Threats to Carp Industry habit in 2000

  • Spring Viremia of Carp (SVC)

  • Koi Herpes Virus (KHV)


Major disease threats to carp industry17 l.jpg
Major Disease Threats to Carp Industry habit in 2000

  • Spring Viremia of Carp (SVC)

    • OIE listed

    • hosts: most carp species, goldfish, and some catfish species

    • rhabdovirus (ssRNA, enveloped, cytoplasmic replication)

    • acute hemorrhagic infections.

    • distribution: mostly Europe, but some recent outbreaks in Middle East and in North America.


Major disease threats to carp industry18 l.jpg
Major Disease Threats to Carp Industry habit in 2000

Koi Herpes Virus (KHV)

  • affects Koi & common carp.

  • Emerging disease (not yet OIE listed).

  • dsDNA, enveloped, intranuclear replication.

  • systemic infections with severe gill necrosis, excess mucus, petechial hemorrhages in skin & liver.

  • > 80% mortality typical when water is 18-27 C

  • major losses in Western Europe, Israel, USA (1998); Indonesia (2002), Japan (2003).

  • major threat to world carp production especially to China (70% of global carp production & major source of animal protein).
