When do koi fish breed

Another consideration to make when breeding koi is size. Female koi that are larger in size will endure the breeding process better than smaller ones. They will also produce larger eggs, making larger and healthier baby koi that grow quicker than smaller fry produced by smaller females. Place the female koi in the breeding tank first. Give her time to get acclimated to the new environment.

She will explore this new space at this time. Once a female begins nosing around breeding areas, she is ready to begin breeding. Add a male to the tank. The female will then release pheromones and they will breed overnight.

The male wrestles the female in an aggressive manner by head-butting, biting, and shoving her. This is in an effort to push her towards the breeding foliage. During the wrestling match, the female koi releases eggs. These attach to breeding foliage and are met by the released milt, or sperm. The milt enters the eggs which are then fertilized. At this point both koi stop and eat a few of the eggs. The process is then repeated over until the the female tires and stops responding.

At this point, she should be removed and placed in the nursery tank. The male can then be returned to the pond. Stay tuned for our next post the basics of koi breeding and the aftercare for the newly spawned koi eggs!

These should be visible around the rocks and plants at the edge of the pond. The eggs will be clear, round and roughly the size of a grain of salt. Sometimes, however, the eggs are eaten by the fish. After the activity dies down and the mating ritual appears to be over, it is a good idea to look at your fish to check their condition. You should ensure that they are being properly aerated, especially in very foamy conditions. Spawning is an interesting activity to witness, if sometimes a little disturbing!

A few weeks later you could be lucky enough to find a host of fry swimming happily in your pond.
