Koi fish are a domesticated form of the common carp and are kept for ornamental purposes in outdoor ponds. Koi fish reproduce through a process called spawning, in which the female fish lays eggs and the male fish fertilizes them.
The eggs are then incubated in a special chamber in the pond until they hatch. Koi fish reproduce relatively quickly, with a typical spawning season lasting from late spring to early summer.

How do you know koi is pregnant?
Koi are known to become pregnant through either artificial insemination or natural mating. Artificial insemination is when a male koi is introduced to a female koi without the involvement of a mate.
This is done by placing a sperm donor in the male’s aquarium, and the female will then swim up to him and deposit her eggs in his body. This can be done several times over a period of several weeks in order to increase the chances of success.
Natural mating is when a male and female koi come into contact with each other in the wild. If the male is ready to mate, he will chase the female around and attempt to mate with her.
If the female is ready to mate, she will lay her eggs in the male’s body.
