How Do Koi Fish Reproduce?
Koi fish typically mate once a year for about 6 to 7 years after reaching sexual maturity. Some breeders manage to prompt koi to mate more frequently, but annual breeding is the norm. Koi romance takes a few hours, and experienced breeders place the male with the female in the late afternoon. Normally, spawning happens just after sunset.
During spawning, the male koi will become extremely aggressive. Male fish will pursue the female koi around the pond, smashing into them and trying to herd them into a tight group. The female koi will release eggs as the males chase her, and these eggs will attach to breeding foliage. The released milt (or sperm) from the males will fertilize the eggs, and the fry (baby koi) will hatch a few weeks later.
It is important to be prepared when koi are ready to spawn, as they can breed quite suddenly and without warning. Make sure to have a separate breeding pond set up in advance, as well as plenty of food and oxygen for the fry. If you are not planning to breed koi, it is advisable to remove the males from the pond before spawning season to avoid aggression and injuries.
