Koi Herpes Virus

The signs of KHV often non-specific. You need to monitor your Koi Fish, if your Koi remains near the surface, swims lethargically, exhibits respiratory distress, has gill lesions, has gill mottling with red and white patches, bleeding gills, has sunken eyes, pale patches or blisters on the skin and uncoordinated swimming. The KHV seems to spread in the same ways as most herpes viruses: direct contact with infected fish, with fluids from infected fish, and/or with water or mud from infected systems. Once a fish has been exposed to the virus, it will always be a carrier. There is no known cure for Koi Herpes Virus. Mortality related to Koi Herpes Virus typically occurs between 18°C and 27°C. Almost no mortalities occur below 18°C, and there has been no reported occurrence of the disease above 30°C.

How do you know your Koi Fish has KHV? You need the assistance of a fish health specialist and a fish disease diagnostic laboratory. There are direct and indirect methods.

Direct methods include: virus isolation and identification (it means growing the virus or not) and PCR techniques (it means testing for the presence of KHV genes).
Indirect tests for KHV include ELISA testing, which looks for antibodies produced by the fish against the herpes virus These testing method can give proof that a fish was infected with KHV. This indirect test cannot determine if the fish is still infected with virus, so it is not recommended as a primary diagnostic tool.

As I mentioned there is no known treatment for KHV and the mortality is very high. If your Koi fish have been diagnosed with Koi Herpes Virus unfortunately, you have not got other choice than depopulation (it means eliminating the entire population). This approach should be followed by disinfection of all materials and systems that have contacted the infected fish.

Benefits of Koi Ponds

The presence of a pond on a piece of real estate raises that properties “marketability” many real estate agents will tell you. This makes it easier for the agent to attract prospective buyers to the property and often plays a key role in how quickly that real estate will sell and at what price..Buyers are drawn to real estate that have such added amenities as ponds and the mystical beauty they hold and many of them are willing to pay higher asking prices to purchase a property that contains a pond. Real estate that has real market value not only increases the likelihood of a homeowner getting a higher asking price from a buyer, the real estate surrounding a property having a Koi pond are also benefited with higher values.

Koi fish pond owners report that having a personal pond to enjoy at their leisure allows them to relax and reduce the amount of stress that the average always-on-the-go lifestyle that most of us lead can cause. De-stressing near the water’s edge is also a time for getting in-touch with one’s inner- spiritual self as well. Many of these Koi fish pond owners share that they feel “rejuvenated” after spending quiet time near their pond. They report a sense of “centeredness” and feel they are more capable of handling the stresses of everyday life head-on.

Some doctors have begun to voice their opinions about the benefits of having a personal Koi fish pond. They have gained these opinions by witnessing improvements in such medical conditions as high blood pressure, anxiety disorders, and some heart conditions in patients known to have their own personal pond. Stress can exasperate these conditions and doctors are always looking for ways they can recommend to their patients for reducing the amount of stress in their lives for better health. Doctors have even found that many stroke and heart attack sufferers recover sooner when they have an area they can access frequently for relaxation, such as with a Koi pond.
