=To worldwide Nishikigoi lovers and dealers=

This is a follow-up report on the outbreak of KHV.
On June 30, 2006, representatives of Niigata Nishikigoi breeders, officials from the prefectural government and the Inland Water Fisheries Experiment Station, and fish diseases trainers appointed for each area by the Niigata District of All Japan Nishikigoi Promotion Association gathered to give a status report and to confirm countermeasures against the disease.

Niigata, being the birthplace and the world’s largest production area of Nishikigoi, has thorough disease control guidelines and has never, not once, let the Koi become infected with the KHV disease.
Unfortunately, a Koi brought in from another prefecture for spawning purposes was a KHV carrier, and KHV was detected for the first time ever from a Niigata breeder’s Koi. The detection was first reported on June 18, 2006 and was officially announced in Niigata five days later on June 23. Please allow me to inform you that we were able to limit the damages to a minimum since prompt actions according to the control guidelines were taken immediately after the detection.

Here is what we specifically did; we made a list of the breeders who interchanged Koi with the breeder who owned the infected Koi. The list consisted of 8 breeders, inside and outside of Niigata. All the infected Koi were culled. Furthermore, we investigated those who may have had contact with the breeder in question. Koi fry that had relation with the infected Koi in some way or another, even if they were free from the possibility of infection, were all culled to eliminate the remotest possibility of infection. We are taking severe measurements based on the “punish those in doubt” principle.
Fortunately since the occurrence of KHV was during spawning season, we have verified that, based on our investigation, no KHV infected or possibly infected Koi have been transferred externally, so there is little possibility of further spread of damages caused by the KHV. In addition, to completely eliminate KHV from Niigata, we are in the process of testing Koi from all breeders, even if they have no contact with the breeder who owned the infected Koi.

After completing these tasks, we will be able to officially issue a declaration of safety in the near future.
This incident will be a good lesson for us. Taking pride in being breeders in the birthplace of Nishikigoi, we are making extra efforts so you will have strong confidence in the safety of Niigata’s Nishikigoi from now on. Your continued understanding and support will be fully appreciated.
