Breeding Koi - Instructions On How To Breed Koi

Firstly, it is important to know that breeding Koi fish should not be left to the beginners. If you have just started out and you've built a Koi fish pond, get to know how to take care and the ins and outs of raising a mature Koi fish. Having this knowledge will help you succeed in breeding Koi fish.
The best time to be breeding koi is between April and July. This is the optimum time for Koi to mate and aim for a one to one ration of male Koi to female Koi.
Koi don't fully mature until they are 3 - 4 years old. So anything younger than this and you are probably wasting your time and anything too much older than this will cause much difficulty in your Koi breeding efforts.
Once you have found some female Koi that you want to breed with, you need to look out for a fuller belly. The female Koi become visibly bloated when they are carrying eggs and this is the optimum time to add a male Koi to the pond. It would also be in your best interests when breeding Koi that you add a male to the pond that is of similar size to the female that is carrying the eggs.
The spawning process is the next step in the breeding of Koi. Having some spawning material can help this process along. This can help protect the eggs from being eaten by the adults. Water hyacinths are the best for harvesting Koi eggs. It is also very useful as these will hold more eggs than most artificial material. However, the adult Koi like to eat these if they stay in the pond too long.

The eggs will take about three days to hatch and then take about a further two for them to consume the egg sack. Congratulations if you get this far!
The best time to begin feeding your baby Koi is when they start swimming horizontally. I must warn you also that not to use a filter when breeding Koi as they will get sucked up and then all of your hard work will be undone. You will need air stones to keep the water moving and aerated. Don't use pumps until your little Koi are strong enough to avoid the currents and big enough not to get sucked into the pipes. koi fish eggs
At this stage it is quite normal for your Koi pond to get a little cloudy and for an unpleasant odour to appear. Don't worry about this.
You can feed your baby Koi brine shrimp or micro worms. Make sure the food you are giving them is small enough for them to eat. As your baby Koi grow, larger Koi fish food can be used. It is a good idea to feed your Koi a high protein type food as this will help avoid cannibalism and don't forget to remove the larger Koi as to avoid many more getting eaten. You will need to try and feed your baby Koi as much as five times per day for the first few months.
If you have managed less than half of your baby Koi surviving to full maturity then you have done extremely well.
I hope this information on breeding Koi has been useful for you.
