Spring Viraemia of Carp (SVC)
Spring Viraemia of Carp (SVC) is a rhabdovirus that
affects several species of fish including carp and Koi.
Mortality is between 5% to 100% and any survivors
then become carriers. This disease has been notifiable
for some years now. This means it is a legal obligation
to notify the authorities should an outbreak be
confirmed and strict controls on the import of fish from
countries where SVC is found have lead to outbreaks
of this disease within the UK to be very rare.

Koi Herpes Virus (KHV)
Koi Herpes Virus (KHV) is a form of herpes virus that
affects carp (including Koi). Mortality rates during an
outbreak are 80% to 100%. Once infected, any
surviving fish are likely to become carriers and can
re-develop the disease at any point in the future,
thereby infecting other fish that it comes into
contact with.

Temperature ramping
Temperature ramping is the rapid raising of the water
temperature in an effort to bring on an outbreak of
KHV.

A skin scrape
A skin scrape is when a sample of mucus is taken from
the body of a Koi for examination under a microscope
in order to identify external parasites.
