Koi Artificial Breeding: Stripping and Fertilization of Eggs
Вставка
- Опубліковано 15 жов 2024
- This video demonstrates the process of koi artificial breeding and includes stripping of eggs and sperm from koi breeders, and artificial fertilization of eggs. In order to remove adhesiveness, after fertilization eggs are placed in McDonald incubation jars where they are vigorously moved in water/milk suspension by air bubbles for 50-60 minutes. Then air flow is substituted with water flow for further incubation of eggs. Additional information on Koi Artificial Spawning can be found at:

I used to use this method to spawn my Goldfish back in the 80s when I was 12, I learnt a lot from this, haven't seen this method in over 30 years, im surprised the eggs can be treated that harshly tho in the tubes and remain fertile, whats the process after this, like to see the end result or where you leave eggs to incuabte and after where do you transfer the fry.....thanks
this is really fascinating
The fish look calm! Did you use anymedicine to keep them look calm? Sir
what is the name of the anesthetic? and what proportion should be used, thank you!
please make vedeo about eel breeding also.. thanks for this vedeo
What was your determination of the koi being ready?
Fascinating. Always wanted to know this, but Can one hand spawn koi fish, even when its not their mating season or wait until its mating season?
What's the ideal water temperature for incubation?
The water temperature can vary in wide range: from 18 to 28 degree C. The optimal temperature for incubation is 21-24 degree.
Dude what happened with the female/male koi fish after egg stripping it? I heard about because of the handling stress the fish die, it is true?
No, it is not true. If fish are treated properly they are completely OK after spawning. Stress to fish should be diminish as much as possible. Therefore, it is very important to use anesthetic during stripping eggs or sperm.
What kind of anesthesic can I use ?
@@KSUAquaculture can u mail me with information on breeding Shiro utsuri and doitsu Showa. koekemoerarmand49@gmail.com. Please!!!
will milk powder diluted in water work?
or only liquid unprocessed milk ???
also , is there any other way to remove the stickness apart from milk ?
- Suspended milk powder should work. It is possible to try talc powder or silt (mud from pond’s bottom). There are some other methods but they are more complex.
How would we know if the female already have enough eggs?
What's the difference between wet and dry stripping???can anybody answer,please...
So the milk can i use any milk as long it is milk then after 1 hour of tumbling i can remove the milk
No details?How was the koi sedated for this vídeo,thats wath i want to know?!!
What did you do to make the fish not move? I've netted out some kois that size and they'd be flopping everywhere let alone let you squeeze 'em like that.
We anesthetized them (made them moveless temporarily).
interesting. thank u youtube for recommend this
How did the McDonald’s jars go clear? What happened to the milk component in the water? Did it get cycled out?
During about one hour eggs are moved in milk suspension by air bubbles. Then air supply stopped but water flow is turned on. So, milk suspension is washed out from jars by coming water.
Great job more fry this way new subscriber Barry Manchester England 👍 👍
and what is the role of milk ..... did not understand the role of milk
Koi eggs are very adhesive (sticky). Because during natural spawning scattered eggs are stuck to plants, rocks and other substrate. Milk suspension is added in order to remove eggs’ adhesiveness. Drops of oil, other particles from milk surround eggs and prevent them from sticking to each other. After moving by air supply for about one hour, eggs lose their adhesiveness. Without adding milk, clumps of eggs would be formed and it would impact severely the process of eggs’ incubation.
Thanks for you usefull training can we get the video of this training? so we can go fir them.
Can i make my own mcdonald jar? do you have some pdf article on how to make one? are there any specific pH for the water and milk to be use? hope you can answer me. Thanks! btw
Don't you rinse the fertilized eggs to prevent the polyspermy before pouring them into the jar?
Eggs of all teleost fish (including koi) have only one micropyle (opening in egg's membrane through which spermatozoon enters the egg). (In contrast to sturgeons and paddlefish whose eggs have multiple micropyles.) Therefore, for teleost fish polyspermy is not a problem; you can use any amount of sperm for fertilization and no rinsing is needed.
whats with the feather
The eggs are very fragile and the feather does not damage them.
armyperson59 so they dont waste the egg its very fragile
does this tecnique also work on carp? thanks for this video
Yes, it does. Koi is an ornamental (colored) form of common carp. Techniques of their breeding are exactly the same.
I would like to know how effective is this process or (Artificial breeding ) koi is? is it possible to get 100% or .......
i whould like to breed koi Artificially...
thanks.
dear I have a problem in the fish eggs become white and die egg whiter solution
Usually if eggs become white quickly this indicates that they are not fertilized.
Any milk work? Your normal grocery store pasteurized stuff?
+Craig Mullins Yes... Whole milk or 3% milk (red cap) from grocery store. Then follow the noted rate of dilution in the video.
I'm sorry can u explain to my the water flow step ? It comes after the air flow step . I understand how to do that step just need bubbles but the water one has me confused ? I just pump water in there ? I feel awkward asking this question as nobody else has had my issue
Moving of eggs in jars by water flow is typical mode of incubation. Vigourous moving of eggs by air flow from the begining is needed only for removing of egg adhesiveness. Supply with water at this stage is not sufficient for this purpose.

This eBook describes and explains in detail all stages of artificial koi breeding shown in the videos and also provides some general information on koi reproduction and its hormonal regulation.
how will i know that koi is full of eggs and sperms
I like it.....
That’s cool
I wood like to learn to breed on care for koy fish
😐
