Japanese koi fish tend to live much longer – their average life span is 40 years! We will examine the factors that contribute to the dramatic difference in the lifespan of these fish.

Genetics

Genetically speaking, the Japanese koi is a more advanced breed than the domestic koi. They are larger and have a longer lifespan than their smaller cousins. In particular, breeders in Japan pay great attention to rearing their koi in a way that significantly enhances their genetic resources.

Western breeders trying to match the size of Japanese koi by making them grow faster could also shorten the life of these domestic koi over time.

Meanwhile, breeders outside of Japan may tend to warm up their pool temperatures during the winter so that the koi can continue to grow and not go into hibernation.

So remember, if you want to prolong the life of your koi, avoid overfeeding and let it hibernate during the winter!
