- It all starts with the Koi breeding process, the most important activity for a Koi Farm which determines the future of the farm. It requires knowledge and skill, which in Koi breeder families is passed on generation on generation. Whereby most of the breeders make use of a manual spawning process for their best Koi varieties, in order to maximize the number of offspring.
In this video we will share with you how Japanese Koi breeders perform their Koi breeding activities. We take a look at the Marudo Koi Farm, where we spend time together with the breeders to get a better understanding of the Koi breeding process. From preparation until the release to the mudponds.
The Marudo Koi Farm, just like many other Koi farms in Japan, make use of concrete ponds as spawning areas. Each of the ponds is provided with a small mesh net and several spawning brushes. The female Koi is placed in the spawning pond for several hours. Thereafter usually two, sometimes three male Koi are placed in the same pond to get the female ready and in the mood for spawning in the next upcoming night.
Most likely during the night or in the early morning the oyagoi, or parent Koi, will start spawning. At Marudo however, the koi breeding process is not done on a natural basis. For this reason, the Marudo staff is checking each hour if spawning activity already can be spotted. This means a selected number of staff have to stay awake during night time and observe the behaviour carefully.
Most Japanese Koi breeders choose to manually breed Koi to enlarge the number of eggs that will be fertilized. This roughly increases the number of offspring by 3 or 4 times the amount. Especially for varieties kohaku, sanke and showa the breeder wants to maximize the number of offspring. In order to have a larger amount of offspring to select from. Already in the first selection, at an age of 3 to 4 weeks old, roughly only 10% of these offspring will be selected for the next round. For one coloured Koi, like the chagoi and karashigoi, the Marudo Koi Farm applies the natural way of breeding. As for these variety of nishikigoi it is less important to have large numbers to select from.
At the moment when the oyagoi start to rush and the male Koi more aggressively bumps into the female oyagoi, the Marudo staff will start to prepare the manual process of breeding. The female Koi is threatened with the saline water, to ensure the Koi is bacteria free and disinfected. As the breeder wants to prevent to have any water in the bowl with eggs, the Koi is rolled in towels.
The Koi is turned around above the bowl and carefully as many eggs as possible are extracted from the female Koi. Large female Koi produce over one hundred thousand of small eggs. The male Koi are netted and sedated in a Koi bag one by one. A liquid relaxant is added in the Koi bag, this will make the process of extracting sperm easier. Thereafter the sperm is extracted.
The next step is to mix the eggs with the sperm. At Marudo Koi Farm, the female eggs are split into two or three batches that will be mixed with sperm of two or three different male Koi.
The eggs are carefully dispersed over the spawning brushes, ensuring as many of them will stick to the brushes. The breeder wants to prevent that eggs will join on to each other. Too many eggs that stick together or to each other at a single place will decrease the amount of successful hatches.
Around 7 days after spawning, the newly hatched Koi fry will be counted and prepared to be transferred to the outside grow ponds. The so called mud ponds. From now on the Koi fry are ready to become true Nishikigoi. In these mud ponds, the Koi will develop and grow quickly.

Hi Steven, thanks for your compliment!

Yes, the parent is quite a good Koi!
Hi, do you know what product they use to relax the koi before sedation? I tried to artifiicialy spawn this morning but no eggs could be extracted once sedated. In the bowl with sedation there are eggs but once out of the water impossible to get some eggs out.... thx!
Hi, normally you should be able to quite easily extract the eggs when the female is ready to release her eggs. Were the eggs easily flowing out when you turn her around before sedation, without having to use pressure? Then normally it should be quite easily possible. I'm myself not sure what exact product is used by the breeder.
@@Aboutkoi Yes, that was what I thought also. They were spawning in the spawning pool for about one hour. There were eggs in the sedation bowl so she was ready I think. But no luck after sedation. That's when I went searching and your movie is the first one I found where they talk of a relaxing product. In the past I releaved a large karashigoi of her eggs this way and she had no problems releasing her eggs and let them flow freely.
Nice that you are trying to breed by yourself though! That surely is the best way to learn more about the development of Koi in their first years. Practice about what will happen with the colours and pattern during development.
@@Aboutkoi Thx... you can check the development and how I am doing on my UA-cam Channel :-) ua-cam.com/users/MrBelkoivideos
Looks good!
What is the food for the larvae at the age of 2 days, and what is their food in the clay ponds?
Artemia/Brine shrimp is used for young Koi and in the mud and clay ponds it is all natural food in the first days. Including Daphnia, a lot of breeders also give powder based on fishmeal they can eat.
Hello..how you distinguish between males n female
A video where I explain the difference in male and female Koi and how to identify them is coming soon, stay tuned! 😉
Do they turn the discarded koi fry into fish meal?
At some breeders this is indeed happening. It depends on the breeder.
How big a koi fish that knows lays eggs?bro thank you
It depends on the age. From 3 years and up it might be possible. Let's say the Koi is about at least 50 cm
What food Japanese breeder give to their koi fry
Most important for them is fish meal!
What chemical do they use to make the fish calm?
A tranquilizing solution is used, for example benzocaine. There are several alternatives as well.
@@Aboutkoi ..pls advise
is that a distilled water they used to mix with the eggs and sperm?
Yes that is a possible way!
10 to 20 success rate damn farm world is harsh
It is I guess. Most breeders do love their job though and do their best to create the best circumstances
I thought Donald trump was talking
Aiii, I can't afford his voice over to be in my video's though 😉
@@Aboutkoi still you make interesting Videos about my favorite fish, keep it up :)
Thanks! We surely will be creating more video's!
