Koi Fish Breeding Tips The moon is full. It reflects off the water of a fishpond full of koi. It is April and the koi are getting ready to breed.
For some, this is an unexpected event that leads to the sudden
intrusion of many new fish in their formerly spacey pond.
But for other koi owners, this is an exciting and anticipated time of year.
Those who are excited about breeding koi fish, start the preparation
well in advance of the April to July breeding season, and their hard
work pays off in superb koi of exceptionally high quality.
Breeding koi fish can be a challenge, in part because of the sheer size of the fish.
Koi can grow to be large, which can pose a problem when trying to find space for newly-bred fish in a pre-existing pond.
Having plenty of space for all the fish, including both the parents
and their offspring, is crucial to the health of all the fish.
It is also vital to get good, high-quality fish to breed. High-quality offspring can only come from high-quality parents
. If you are looking to buy koi for breeding, you will have to be
knowledgeable on exactly which type of koi you want and what the
signs of a healthy, high-quality fish of that type are.
A good place to start is the coloring and pattern on the fish.
The vividness of the colors and crispness of the distinction between
colors can often indicate the quality of the fish.
Also look at the age of the fish you buy for breeding. Both too young and too old can be detrimental.
A very young female koi may have eggs that are too soft, and therefore more easily prone to damaging.
You could lose many of the offspring produced by a young koi. On the other end of the spectrum is a koi that is too old.
As you may expect, this sometimes leads to the opposite problem. An older female koi could produce eggs with shells that are too
hard, which may prevent sperm from being able to fertilize them. The ideal age is four to five years old if the koi is intended to be used for breeding.
The weather and even the moon can affect breeding. Koi like to
breed during a season when the difference between the high and
low temperature for the day is very slight.
They also like to breed during the full moon. If possible, aim to have your fish breed when the moon is full or nearly full, as this helps encourage the fish to spawn.
One spawning can result in literally thousands of eggs. The male fish will fertilize the eggs after they are out of the female.
The male will also try to help the female release the eggs by pushing her from each side.
Watch the fish carefully during this to ensure the male does not injure the female.
Even if you’ve done everything correctly up to this point and gotten your fish to breed, your work is not quite done yet.
Even after koi breeding there are steps to be taken to ensure the
continued health of your fish and their offspring.
Separate the fish after the spawning to allow the female to rest.
After this point, it is your responsibility to take care of your new fish and their parents.
With diligence, attention and care, your pond may soon be full of
high-quality, individually bred koi guided from egg to maturity by you.
