Like most fish, koi reproduce through spawning in which a female lays a vast number of eggs and one or more males fertilize them.

Nurturing the resulting offspring (referred to as “fry”) is a tricky and tedious job, usually done only by professionals. Koi produce thousands of offspring from a single spawning.

The males will bump the female koi fish in the pond wall and at the same time release their sperm to fertilize the eggs that the female releases also each time the males bump her.

Will my koi breed?
In a pond setting, koi will breed as a flock, or group. If sexually mature males and females are present in the flock, and if environmental conditions are met, spawning will happen spontaneously. During spawning the male koi will become extremely aggressive.

Can koi spawn more than once a year?
Koi can spawn naturally twice a year, with the first spawning usually being more productive than the second one.

At what age do koi breed?
3-6 years old
A Koi’s prime mating age is between 3-6 years old, but koi have also been able to produce baby koi fish until they are up to 15 years old.
