Ki Utsrui was almost extinct! “Any decisions on control methods for carp in Lake Colac would have to involve a number of agencies including the Department of Primary Industries, which is responsible for pest plants and animals, the Department of Sustainability and Environment, Parks Victoria, Corangamite Catchment Management Authority and Council,” he said. Koi are usually held in closed circuit systems to ensure good health, many of the skills and knowledge refer to the ability of the hobbyist, to create optimal filtering systems and thus an optimum water quality . Parasites are a real pond health issue when it comes to Koi Japanese fish. The re-infected the Koi and did the same thing again. The reasons for this are that KHV is a virus and it has two phases in it’s lifespan. The disease now occurs essentially everywhere carp are raised.
Screening of carp would involve collaboration with epidemiologists to establish the sample sizes, and distribution of samples that would be required to be considered statistically significant. In the spring of 1998, large amounts of food carp and ornamental Koi started to die in farms in Israel. This mysterious virus spread all over Israel and then eventually into other parts of the world, due to unregulated trade. Carp Gill Necrosis Virus has cause tens of millions of dollars in damage ever since the first outbreak nearly ten years ago. The outside world was not aware of the development of color variations in koi until 1914, when the Niigata koi were exhibited in the annual exposition in Tokyo. There are straight as well as indirect techniques. Straight methods include: virus seclusion and also recognition (it implies growing the infection or not) and also PCR strategies (it means testing for the presence of KHV genetics).
(It’s no exaggeration to say that even a drop of tainted water can start an outbreak in a pond.) And keep koi healthy by inoculating your koi with CAVOY, the vaccine that prevents KHV. This is not a subtle request for a donation from every member of all PNKCA clubs to help fund the AKCA’s Project KHV. As long as the aquarium is kept up, the growths will eventually go away completely. This can be combated by raising the water temperate above 86 degrees Fahrenheit for a month in order to suppress the virus long enough for enough antibodies to develop. Although, if KHV is a herpes virus, an “immunized” Koi will infect any other Koi with no prior exposure and then a massive die off will ensue. So, they became skinny, stressed, the conditions were right for koi herpes virus, and voila; there was an outbreak. Several Koi may be needed for sacrifice in order to obtain good samples for PCR testing.
The best way to prevent an outbreak of Koi Herpes Virus in a pond is QUARANTINE. Quarantine is the #1 proven method to stop the spread of disease. Goldfish were introduced to Japan in the 16th century and to Europe in the 17th century. Koi, on the other hand, were developed from common carp in Japan in the 1820s.
