The occasional brush on the fingers as they swim past your hand in the pond or a kiss on the hand while you feed them is ok, but not picking them up out of the water. Even if it’s just for a few minutes, a koi keeper will have to handle it in some instances.

There are show-quality koi at the other end of the spectrum. The best are breeder certified, which means they have stable bloodlines that give them some certainty of passing on their genes to the next generation. Breeder-certified ponds are the most expensive, but they’re also the easiest to find.
If you’re lucky enough to live near a pond, you can usually find one that has been certified by the Association of Zoos and Aquariums (AZA) or the American Koi Association (AKA). The AZA certifies ponds that have been in operation for at least five years, while the AKA has a five-year certification period.
Both certifications require that the pond be maintained in a controlled environment, which means that it must be kept at a temperature of 70 degrees Fahrenheit (21 degrees Celsius) and a pH of 6.5 to 7.0 (6.8 to 8.2 for freshwater ponds).
A certified pond is also required to have a water quality test every two years to ensure that its water is free of bacteria, algae, and protozoa, as well as to monitor the water’s salinity and oxygen levels.

As a result, the price of a single egg can be as high as $1,000 or more, depending on the quality of the eggs and the number of eggs that are produced. In addition to this, there is also the cost of caring for the egg, as well as the time it takes to incubate and hatch them.
This can add up to a lot of money, especially if you are trying to save money for a down payment on a house or car.

This is one of the reasons why there is so much admiration for the fish in Japan and the rest of the world. Environmental factors that contribute to a long lifespan are clean water and a good pond filter, quality koi food, and long cold winters. The cold season will affect the metabolism of the koi and make them more susceptible to disease.
Koi are also a great source of protein for people who are on a low-carbohydrate diet, as they are high in protein and low in carbohydrates. Koi also have a lot of vitamins and minerals, such as calcium, iron, magnesium, phosphorus, potassium, manganese, selenium, zinc, vitamin B12, thiamine, riboflavin, niacin and pyridoxine.
