How to breed Koi Fish in the Philippines
How I breed my Koi Fish
This is how I breed my Koi fish in my own ways. I used indigenous and cheap materials for my breeding tank setup. Other Koi keepers here called it poor man's Koi setup.
Steps in my koi breeding.

- Prepare my daphnia culture.
I prefer daphnia magna since they are easy to kept and multiple fast they have bigger size than daphnia monia but my purpose in using magna for feeding my koi fry is they serve as my filtration too during the first days of my koi fry since you can't install a filtration system in your breeding tank. during the first week of my koi fry I feed them hard boiled egg yolk and most of the time there are egg yolks left uneaten and if this will not be eradicated it will encourage growth of bad bacteria, so in this stage the daphnia magna eats all the leftover egg yolk and all other detritus and organic matter in the breeding tank making the water clean plus their babies are eaten by my koi fry since it is small.
- Choosing the breeders and separating them.
I choose my koi breeders and separate the male from the female for a month or less than a month depending on how fast the tummy of the female koi breeders became swollen. I don't use hormone I only go for natural I feed them plenty of high protein food and live foods, like daphnia, earthworms, shrimp, duckweed, snails and other fruits and vegetables. I choose males that have enough milt. I test it by massaging it's vent. separating males from female will make them stimulate to breed when they are together since they are like a human too. love will make founder when they are away he he.
- Preparing the nesting media and tank
I used a net, yarn or plastic straw as nesting medium because they are free from live predators. I tried using live plants like horn worth before but I was devasted because a number of predators came out from the horn wort live plants because I think the dragon fly and other predator insects eggs sticks on it. The breeding tank I used is trapal and have a bamboo frame. the sizes of my tank usually are just 4x4 meter and have 2 feet deep since after a month I will just transfer them to the mud pond for growing out.
I place them together after a month during the full moon, they are stimulated to breed during the full moon. I also add fresh water to the breeding tank to stimulate them to breed and add the nesting medium the koi female loves to gather them and try to build a nest this is the natural behaviour of a koi in the wild when breeding they will nible the nesting medium and gather them to build their nest. I place the breeders around 6 pm in the evening after placing I will observe their behavior if you notice when you will place them together they will start to acquaint each other right away and after awhile they will begin to chase each other it is still slow first then it will slowly become faster and aggressive once the female is ready to spawn the males can smell the female hormone that female secrete when She is ready to spawn and by the way the ratio of the koi fish is two males and one female. as the spawning started the males will aggressively chase the female and bump it to the nesting medium releasing its sperm and the female releases its eggs at the same time too. It will last around 1 hour if you noticed when the males will no longer chase the female its time to take them out the breeding tank and do 60 percent water change and add methylene blue to prevent the eggs from fungal attacks then add strong aeration.
Hatching usually takes only 2 days here in my place that the eggs will start to hatch because we have a warmer temperature.
I feed them 3 to 4 days after hatching since the yolk in their tummy are gone already and this stage they begin to feed.
