Koi Breeding
Tips On Koi Breeding for Fun or Profit
Koi breeding is a fun and fascinating hobby, but it can be difficult at times. Koi can grow to a large size, and you will have to have quality parents in order to breed high-quality Koi fish.
If you've been caring for Koi for long enough that you feel comfortable with the idea of breeding them, you will want to get suitable parents for your Koi pond. Choose the type of fish that look and behave like you want your offspring to. Even with good-quality parents, only a few of any batch of fry will be as lovely as their parents. Try to keep your bloodlines pure, so that you will be able to consistently breed the highest quality of Koi fry.
Another important aspect of Koi breeding is selecting parents of the correct age to foster your young Koi. This affects the shells of the fry – young Koi may produce eggs that have thin shells and older fish may produce eggs with hard and impenetrable shells. It's best to use a Koi that is about four or five years old, but you can breed with fish as old as fifteen years of age.
When you select the couple to breed, separate them from your other fish for about a month. Feed them well to get them into condition to spawn. It's best to breed your Koi one to one, but you can also pair two males with one female, to make sure a breeding takes place. Don't use any more males though – they might get aggressive and injure your female Koi.
You will want to breed your Koi at whatever time of year in your area sees the least difference in day and night temperatures. If you're breeding indoors, you can breed anytime. Some breeders say that a full moon triggers the Koi to spawn, but this has not been scientifically proven.
Decorate your breeding tank to provide breeding areas for the Koi. Water hyacinths are a great plant for building spawning places. Treat them first with Dipterex to eliminate parasites. Use nets on top of your Koi pond if your breeding pond is outdoors, to prevent predators from getting to your eggs and fry.
Use a larger pond area or tank for breeding, rather than a smaller one. Set up an aeration system with powerful pumps. Don't overdo it with waterfalls and currents from your aerators, though, or it can have poor effects on the spawning.
Raise the best looking half of your fry, or your breeding pond will be too crowded. Sort them as soon as you can by quality, and only keep the best quality fry.
