KHV Information from Momotaro Koi Farm
We are sad to report that our farm, Momotaro Koi Farm, has been infected by KHV. We would like to apologize to all of our dealers and customers who have been inconvenienced by this setback. We know that this news will sadden many people from all over the world who look forward to visiting our farm and caring for our koi.
Throughout the year we have had monthly KHV tests on random koi from our farm done by the Okayama Prefecture Ministry of Fisheries. These check-ups are a law in Okayama Prefecture. Throughout this spring and summer we did not experience koi health problems different from past years. We first experienced signs of a problem with our September Auction Nisai on Sunday October 2. After trying many different medications and treatments we decided that a KHV test was necessary. On Wednesday October 5th, a PCR test showed that these Nisai were indeed infected with KHV.
After the auction many koi were bowled and photographed by koi dealers from all over the world and Japan for their websites and individual customers. During this time, nets and koi bowls were mixed without discretion by many people including our staff. At that time, no koi had any external, discernable problems. It is our fault that these koi were put at such risk.
In the days following the auction, many koi were moved in and out of the auction house ponds. None were mixed directly with customer’s koi, but all ponds could have had possible contaminations with nets, sock nets, or water splashing. Some Tosai were moved out of this house after culling for future growing in another koi house. Within the same infected house, some Nisai were retained and moved elsewhere to be grown and sold in the future.
Since our first positive KHV test we have also found KHV in 2 other koi houses. We are continuing tests everyday as well as manipulating water temperatures to try to bring out any KHV infected koi. Today, the Prefectural Ministry of Fisheries came here for a second time to assess the situation and suggest action. We are beginning to euthanize all koi in infected koi houses, and will continue to euthanize koi until we are satisfied that our farm and facilities are 100% KHV free. We are working with the authorities to ensure all proper methods are followed.
KHV is a problem that the whole koi world needs to know about. We will continue to test our koi, clean our facilities, and support our koi dealers during these difficult times. We are unsure of when or how we were infected, as it is very difficult for a large farm like ours to pinpoint the initiator of a virus like this, but we do have a few ideas. Our main focus now is preventing further spread and doing proper cleanup. We will give more updates as things progress in the following weeks.
Again, we would like to express our deepest regrets that this has happened. Our greatest satisfaction to making people happy with our koi, and unfortunately this malady will temporarily disallow us from doing that. Please look forward to a great future with beautiful, healthy Momotaro koi.
