Breeding Koi fish is very enthralling but can also be difficult sometimes. It is because Koi grows up large and also because you have to find good parent in order to spawn superb Koi offspring. In case you aren’t familiar with Kois, they are colorful fishes belonging to the carp family that were initially bred more than 200 years ago in Japan.
If you are among those individuals who want to breed Koi, the ideal months to start it is between April and July. These months are said to be the perfect time for mating.
Here are several other important aspects that need to know to get started.
· Quality of your Koi. In your aim to breed Koi, the first thing to consider is the quality of fish. Kois that are suitable and high quality will surely spawn good quality offspring. Hence, you need to select the parents that will give you Koi fishes that match your pattern and coloration preferences. It is advisable to maintain the cleanliness of the bloodlines of your Koi in order for them to make first-rate Koi fish.
· Age of the Fish. The age of your Koi also needs to be considered. Those that are young or old enough may not easily breed. Their age also influences the eggshells’ quality. The young females usually spawn thin shells, which may hardly survive while older females can give off hard shells wherein sperm can’t make a way into. The ideal age for a Koi to breed is 4-5 years.
· Fish Conditioning. Once you already have Koi males and females for the breeding activity, you need to condition them for a year. Your tank or spawn pond should contain two males for every female Koi. Male Koi will usually chase the females or rub the side of the female’s body using their heads. Through this, females will be inspired to spawn.
· Preparing the Location. There are various things that Koi needs in order to breed. These are:
- Medium or a Place where they can lay their eggs – Medium for Koi breeding can be branches of evergreen that are tied together and perched. They can also lay their eggs on the grass, which is usually found in the bottom of the pond. The media can also be artificial such as PVC pipe having nylon rope that’s fastened and frayed.
- Privacy – The fry typically needs a place where they can hang out after being hatched. Since they aren’t capable of swimming yet, they have to be placed in a secure and safe area.
- Water Quality and Right Pond Temperature – aside from good quality of water, the breeding pond should have oxygen and proper aeration. After spawning, water in the pond should be replaced.
- Eggs. The eggs of Koi are very sticky so they will adhere well. If the eggs develop like a fungus substance, there’s nothing to worry about. That could also contain lots of eggs. Good-quality eggs are usually translucent while the unfertilized eggs are white. The eggs should be separated from the parents because together with the fry, they can be eaten up.
- The Fry. After hatching, let 3-4 days pass without feeding them. After this period, they should be exposed to a very good source of food. The ideal temperature for growing fry is 70-75 degrees. During the first month, you should start culling.
Koi breeding and raising can be a whole lot of fun, but you need to understand the basics if you want to be successful.
