Picking the Parents
Choose the male and female from the same variety you want to reproduce. If you wish to cross-breed, choose varieties carefully and research more on the kind of offspring you're most likely to get. Keep in mind that the dominant genes are the ones from the male parent.
Be sure to use only adult fish for breeding applications. The appropriate breeding age of the female is from 5 years onwards as their eggs are larger and more fertile. Beware of breeding females under the age of 4 years old as your koi might lose their colors and patterns if bred at an early age. The female koi is ready to spawn if you observe it sucking at the sides of the pond, aiming to clear an area where she can place her eggs.
Male koi can start spawning upon reaching the age of two when small white nodules show up on the pectoral fins as well as on the gill plates. You can really feel those areas to be rougher than usual. You can make use of the younger males every two weeks but allow a longer time interval for older males to maximize their fertility potential.
Spawning
Koi will naturally spawn in the early summer months. If you let that to happen, however, the eggs will only be consumed by the some other fish while the females get more stressed. The net outcome will be offspring of inferior quality. Besides, a pond filled with eggs will harbor bad bacteria that will negatively affect the well-being of your koi population.
If you are sincere in koi breeding, you will have to use a controlled approach. Put the koi brooders in a separate pond and make sure to hang spawning media from the walls of the pond. The female will need them to place her eggs which can be somewhere between 100,000 to 500,000 depending on her mass. You can use ropes, artificial grasses, natural plants, vegetable sacking, or cloth strips as spawning materials.
During courtship, the male chases the female and forces her against the walls of the pond to induce spawning. If there are two or three males in the pond, they will group on her to simultaneously fertilize the eggs.
You will find out that the Koi have spawned if there is foam on the water surface and the distinct scent of ammonia. By then, you will need to move the female to another pond where she can regain her strength. Take away the males too; or else, they could feed on the eggs.
Culling
The fry will break out of their eggshells in 5 to 7 days. They will keep on growing and you can begin culling on the sixth week. Remove the baby koi with deformities like missing fins, deformed mouths, colorless, and also single color.
Culling is vital in koi breeding. You need to reduce the numbers so the great quality fry can reach a reasonable size by the end of the season. If you don't cull, the undesirable koi will still compete with the good koi for food and space. Culled fry are usually destroyed or fed to the other fish.
You can release your chosen young koi in a mud pond that is very rich in organic food. As they grow larger, you can continue the selection process until you get only the perfect koi that you want to keep or sell.
