Do you know what this is?
It’s Carpe pox also know as Koi pox or Fish pox. Do any of your koi or goldfish have this?
Fish infected with carp pox have distinctive white, waxy lesions that appear during the low temperatures of winter and early spring. The lesions tend to reduce as temperatures rise in the summer. It is caused by a virus known as Cyprinid Herpesvirus-1.
Outbreaks of KHV and the gold- fish herpesvirus disease can be treated by elevating water temperatures into the mid 80s (°F), but any fish treated in this manner must be considered virus carriers with the potential to infect other fish. Signs of carp pox disease disappear at water temperatures above about 72 °F.
This disease usually affects carp and koi, but can also infect other types of fish, and is therefore also named fish pox.
What is the treatment for Koi Pox? Since it is a herpes virus, once a fish is infected, it is a carrier for life. This is a characteristic of all herpes viruses that store latent viral particles in neurons of the animals they infect. Like KHV, there is NO TREATMENT.
Koi herpes virus can be spread through direct contact with infected fish, as well as through contaminated water and equipment. Stressors such as poor water quality, fluctuations in water temperatures, and overcrowding can also contribute to the development of the disease.
Carp pox is an aesthetic disfigurement rather than a life threatening condition except in the most extreme cases and no attempt should be made to remove or burst the lesions.
Many koi/goldfish owners remove infected fish from their ponds.
