It is mainly caused by carp rod virus. It is a common disease in brocade carp breeding. It is only prevalent in spring when the climate is getting warmer (water temperature 13 ~ 20 ℃).

It mainly harms the koi over one year old, and the fry and breeding fish are rarely infected. Most of them are raised in open-air ponds and in indoor fish tanks, and the incidence is less because the change of water temperature is not so violent.

In the cold water temperature period in nature, the disease is chronic, and when the water temperature warms up in spring, the shellfish is acute, and the mortality rate is high.

Mainly at the end of winter, pay attention to clean up the sediments of the pool, strengthen the disinfection of water sources, and change water regularly to prevent drastic changes in water quality.
