Koi Disease: The Things You Need To Know About Koi Herpes Virus

8 May 2009 114 views No Comment

The KHV (or Koi Herpes Virus) is a fatal disease which has recently emerged from the industry. The first outbreak happened between the years 1998 and 1999 in Israel. And since then, outbreaks have been reported throughout the world, especially in places like Asia, United States and Europe.

Just like most of the Herpes type of viruses all throughout the world, the KHV is believed to remain with the infected fish for life. The fish exposed to the disease at a certain point are instantly considered as carriers! The mortality rate of the fish exposed to the disease range from 60 to 80 percent.

These fish are very prone to the virus. In order to prevent your fish from contracting the virus, make sure that they never get exposed to it. Having the appropriate knowledge of the virus would slim the chances of making your fish catch the virus.

Facts about KHV:

A little bit of information has been gathered about the disease since its reported outbreak in 1998, and knowing important facts about it can help you in keeping your pond healthy. Once the fish has been exposed to KHV, it will always be a carrier for the rest of its lifespan. Even with the right treatment, these fish shouldn't be transferred to another pond or habitat (you wouldn't want spreading the infection in the pond)?).

Take note that temperatures around 74 degrees Fahrenheit activate the disease (which allows for the testing to see if the fish really have the virus or not). Stress do not cause the virus, but it can cause the disease to gain a higher mortality rate. The spreading of the virus will happen if the fish comes into contact with an infected one;if it comes into contact with tools used in handling the infected one; if it will be exposed to the water in which the infected ones thrive; etc. Sad as it is, there is no cure for the virus.

Preventative measures to stop the disease from spreading:

If your fish gets the virus,the only way to make sure that you don't infect any other fish is by depopulation. This process is the elimination of your whole pet population. It may seem cruel, it's truly the best way to make sure that no other fish will ever catch the virus.

After you purchase your fish, it's good to quarantine it separately from your current population in a period not less than 15 days. With the knowledge of the exact temperature level to activate the disease (around 74 degrees Fahrenheit), this will allow you to expose your Koi to the right conditions for the virus to show itself. Those that thrive in these conditions within this period and don't develop any symptoms have less chance of getting infected.

Quarantining your pets means total isolation; never allow anything to come into contact with the infected ones (especially those items that may come into contact with the current population). Use separate food, tools and water. Ensure that those tools you have used for your quarantined pets stay in the area in which they are used always.

Proper procedures in hand washing is needed when handling your Koi and its items within the same timeframe. These steps are very important for the prevention of the disease.
