Koi Herpes Virus (KHV)

A Serious Issue Out There!

LET ME BE CLEAR….WE do not and have never had this virus. This article is to help those that buy fish from multiple places…especially imported fish.

Biology, History, Quarantine, and what it means to you.

For those of you that don’t already know, this virus was viciously sweeping through the Koi world both nationally and especially internationally starting back around the early 2000’s. It is still around today and actually known to be in many wild streams, lakes and rivers in the USA and abroad. Japan still to this day has serious issues with this virus. As a matter of fact, now in 2019 it has hit quite a few Japanese breeders to some degree, and as well some of these fish were sent to the USA after they were unknowingly purchased by some American dealers. Of course these fish were sold and purchased without the breeders or the USA dealers knowing the virus was present. You see fish can carry the virus until certain stress factors as well as changing temperatures and ranges that cause the virus to break. Carrier fish can have the virus and never get sick themselves. However once introduced to naive fish the virus can and will spread! Some of these dealers that got the virus did the right thing and announced it to the public. I can assure you others got the virus and did not even realize it, and therefore sold the fish! Back when it started there was widespread panic running through the Koi world. Because it is still around and common you still need to be VERY careful where you acquire your fish.

It has always been an important factor where you purchase your fish, but today it is even more important with the recent outbreaks in Imported Koi. There are many farms and dealers out there that do not have the proper quarantine, treatment and biosecurity measures in place, and this has caused the spread of this virus to continue to this day in 2019. How bad is it? Well it is so bad that here at Hanover Koi Farms we have closed the doors to any imported fish whatsoever, be it foreign or domestic, and have been a closed farm since 2007! . Even though we are totally set up biosecurity-wise for bringing in fish from outside sources, we will no longer do it. We have one of the most biosecure farms on the planet, as well as extremely good quarantine protocols, but to further protect my farm from the virus, we have closed the doors to any fish from outside sources. For the most part we never did this anyway, except for purchasing new broodstock. I would love to get some more broodstock from Jap[an but it is simply too dangerous with these recent outbreaks over there. The problem over there is far worse than most hobbyists know.

So with that said, if you still decide to purchase imported fish, then do the proper research and ask them what their protocol is as for assuring their fish do not have this virus. At minimum make sure they have a good biosecurity program in play. This includes a separate system for fish from each breeder they purchase from. If they allow fish from multiple breeders come in contact with each other, there is a far greater risk that they could contaminate their entire population if any one breeder sold carrier fish! then it is a MUST to have a proper quarantine setup. These fish should be in the Quarantine for at least a year in my opinion. Also there is a very specific protocol for housing and treating these fish during the QT process.
More importantly though is that you have a proper QT system that is completely separated by distance and other means from your existing population. The time frame is up to you but as I said I would QT them for at least a year under very specific and controlled protocols. I can’t stress enough how serious this issue is right now, and how dangerous it is to buy Imported fish without the proper quarantine.

While there is testing available for this virus, to date these test are simply not reliable. There is currently NO TEST that can assure with 100% certainty that a fish is not a carrier of this deadly virus. So do not risk your current population no matter whether the fish have been tested or not!

You can read more about proper quarantine on our website at the link below;

Koi & Their Perceived Value

Here is a video that helps new hobbyists begin to understand Koi and their perceived value. I personally would have titled this piece “Why Koi Fish CAN SOMETIMES be so Expensive”, as most Koi sold are within anyone’s budget that would want them.”Some of the info in this video is a little off, but for the most part it is generally informative if you don’t understand the world of Koi. No matter I can tell you that some people have more money than sense to pay 1.8 million for a fish!

UPDATE: 10/10/19 This Koi in the video below, purchased for 1.8 million dollars has died!

With that said, understand that the world of Koi and their value is very similar to the world of Dogs. Their are mutts, full breeds, and show winners! Yes there are actually Koi shows. Understand now that Koi are not all valuable just because they are Koi! As a matter of fact, most Koi sold in the USA are considered “mutts”. These are low grade flock -spawned fish of poor quality. Here at HKF all of our fish are selectively bred for superior quality.  With that said we still offer various grades of these selectively bred Koi to meet anyone’s budget. Read our website, or better yet come to the farm and we can teach you what makes one Koi better than another, and thus more valuable. This is clearly visible in our grading sytem and pricing.

Understand that the majority of the Koi offspring do not even make the cut here at the farm. Anywhere from 50% to 95% of each spawn is culled and only the smallest percentage make the cut to our retail tanks! So don’t pay too much for “mutt” Koi just because they are Koi. The Koi that do not make it are referred to as “culls” and this is the grade being sold by many places out there! Not here at HKF!  We can show you the difference in person when you come to the farm and you will quickly see the difference in our fish as compared to what you have seen elsewhere.

So Understand the difference in grades of Koi and pick whichever grade suites your taste and budget. You can see out price list and grading system here:

New for 2018

HKF Pond

(a new division of Hanover Koi Farms)

Full Service Pond, Watergarden, and Water Feature Construction & Maintenance


Over the many years in the Koi business we have seen and heard many horror stories from our customers associated not only with new pond design and function, but with the maintenance associated with them as well! Not only does a pond have to be designed properly , the maintenance has to be done in a very specific way or the fish may be negatively affected or even killed. Cleanouts especially for example are one of the most common ways fish are killed or stressed directly or indirectly. I say indirectly because the fish are put back into the cleaned pond , but they were not re-acclimated back to the pond properly. They are still alive but then 2 to 3 weeks (or more) later they start showing signs of illness! This is usually a sign that the fish were severely stressed while in storage during the cleanout, or when they were put back into the newly cleaned pond with new water and not acclimated properly. Most often however folks don’t realize that the symptoms of ill health or fish deaths that they are seeing 2-3 weeks after are a direct result of an improperly done cleanout!

The reason for these horror stories is due to the fact that new builds, maintenance and cleanouts are done by landscape companies that specialize in just that…the landscaping around the pond, watergarden or water feature!

At HKF Pond we have the landscape expertise as well,  but more importantly we are experts in ALL aspects related to these features with special emphasis on the water clarity and fish health and safety.

So new for the 2018 season we would like to announce a new branch of Hanover Koi Farms …HKF Pond… With this we will be doing all facets of pond, watergarden and water feature construction, and full service maintenance. This is to include cleanouts of all these type of  features. Ponds, watergardens and water features are three very specific and distinct features from one another, and it is very important you know which you have or which you want to have built. To see a detailed description of the difference between these outdoor features click here. At the bottom of that linked page as well is a contact form if you are interested in a FREE ESTIMATE , and/or  to schedule  a FREE Limited CONSULTATION for new builds or maintenance.

We WILL respond to all emails inquiries within 24 hours!

In previous years we did only designing of ponds, as well as selling of the equipment associated with them. We will still be continuing to do so, but now  with the formation of  HKF Pond  we will also be involved with watergardens, and water features like pondless waterfalls and such. As well we will be  selling all the required equipment associated with each.  You can be assured we will be using only proven techniques and equipment that we know work, is reliable, and as maintenance free as possible. With our many years experience in this industry you can be assured of quality all the way around! We know how to protect and care for your investment in fish!

So contact us preferably by using the this link to submit a Free Estimate Request form located here; or contact us by email to [email protected] Phone call inquiries are the least preferred method of contacting us as we do not have anyone manning the phone full time.

We WILL respond to all emails inquiries within 24 hours!

Important Cleanout Notes;


For cleanout service there is an initial service fee of $95. Each cleanout is billed on a time and material basis of $85 per hour starting with the first hour on site and for each hour until complete.Using the information you supply on the form below we can usually give you a reasonable ballpark total that you cleanout will cost. The more accurate the info you supply to us, the more accurate we can be on out estimate of total cost per cleanout.

 Any trucked- in or water purchases needed to refill the pond or watergarden will be the cost responsibility of the customer unless otherwise noted, and will then be additional to the original cleanout quote.

After the cleanout the pond will be filled with our supervision only to the point to safely accept and reacclimate the fish. This is usually around two feet in depth maximum. Complete filling and monitoring will otherwise be the responsibility of the customer unless otherwise noted, and then may be an additional charge for time on an hourly basis.

The costs of any water additives such as dechlorinator, baking soda, salt etc. are not included but can be supplied for additional costs.

Additional Services Available

A cleanout is the perfect time to address others issues that may need to be addressed. The services and materials listed below will be an additional cost to the original cleanout quote unless otherwise noted. These services will be offered at preferred pricing because we are already on site.

The permanent removal of all rocks and gravel from the bottom of the pond as this is not a healthy environment for the fish, you, your pets, or water quality and clarity.

Replacing old or improper filter media like lava rocks, bioballs, scrubbie pads etc, as these are not functional in a biofilter and impede proper mechanical and biological filtration.

Adding a UV light is a must for crystal clear water and green water control. A UV light is the only practical solution for green water algae control.

Topical treatment of fish with injuries, ulcers or fungal issues.

Treatment of  entire pond and fish for parasite, bacterial, and fungal issues.

 The request for estimate form below is primarily designed to accommodate a  ballpark quote for cleanouts. Cleanouts and service work are billed on a time and material basis however. With this info we can in most cases give you a fairly accurate estimate of the total cost your work will be without a site visit being required. This helps keep total costs down. However the request form can also be used for quotes for new ponds, upgrades and additions,  repairs etc. Not all info on form is required for these type things. Simply tell us what you are looking for in the “Message” part of the form.

    The New HKF

    All winter long Chris and I have been working on this new website. Finally we are able to launch it in time for the upcoming 2017 season. It is not 100% complete but close to it! Every single article has been updated, and this includes new information added to each. As well, we have added tons of photos and videos to make learning about Koi a little more enjoyable. Not to mention I needed something to break up my long winded articles LOL. We added more symptoms with photos and videos to better help you diagnose any issues you may have with your fish. No one has a more comprehensive website for Koi!

    Also new this season, in the near future we will be holding online auctions for Koi on the website! This feature will be available sometime after we open for the season and get the fish from the ponds to auction. These will primarily be larger fish or packages of multiple smaller fish. With an auction format you will have a much better chance of getting some great fish below retail!

    We are Expanding!

    In addition to the new website, the other big news this season is that we are growing the business and expanding our inventory! No, not more fish…we already have more of those than anyone Duh! We will have a very nice selection of pond plants again, including lilies and all the most popular varieties of water plants and marginals. Even bigger news is we will be carrying outdoor and pond associated statuary, chimaneas, bird feeders and much more as the season progresses! We also increased our pond equipment line as well!

    More Fish Then EVER!

    The retail tanks will be overflowing with thousands of great fish soon! We have more fish than ever, and many new varieties that you have not seen in a while. As usual, you will be pleasantly overwhelmed at our selection. No other place comes close to our selection of Koi and Butterfly Koi. We truly do have more fish in more varieties then you’ve ever seen!

    It’s worth the drive!

    So, if you are looking for Koi or Butterfly Koi, you need to make the trip to the farm. We can say with confidence that you will not find a better selection ANYWHERE! We promise you will be delightfully overwhelmed at the huge selection and the great pricing! If you are within a day’s drive of the farm, we would highly recommend you make the trip. No one has ever been disappointed! Many folks drive as long as eight hours or more to come here, and some even fly in to be able to personally pick their own fish. If for some reason you can’t make the trip, you can always buy one of our package deals online, and we personally will pick an awesome variety of fish for you. You should also keep in mind, however, that we are also very close to Amish country in Lancaster, as well as historic Gettysburg. So you can even make it part of a long weekend or vacation and pick them yourself.
