Which koi are easy to keep? Introduction to koi breeding methods

For broodstock used for breeding, generally choose those over 3 years old, over 60 cm in body length, with pure bloodlines, excellent color and quality, and strong physique.

 Generally, male koi can mature at one year of age, and female koi can mature at one and a half years, but at this time, due to unstable genetics, the offspring produced usually have a relatively low rate of high quality, and it is not easy to obtain good fish, so when conditions permit, it is best to choose those over 3 years old as broodstock.

The intensive conditioning of broodstock should begin in autumn. At this time, the water temperature is around 25°C, and the fish have a strong appetite. Feed with a protein content of over 38% should be chosen, fed at 8% of body weight, 2~3 times a day, while appropriately feeding green feed, such as Chinese cabbage, spinach, duckweed, etc., to increase the supply of vitamins.

Appropriately adding rice, glutinous rice and honey, etc. to the feed can increase fat accumulation, which will be of special benefit to enhancing ovarian development in spring.

Breeding can be carried out when the water temperature reaches 16~35°C, and the most suitable temperature is 22~30°C. There are also cases of breeding in autumn.

In Guangdong, breeding can be carried out almost all year round except in the hottest summer.

The breeding season of koi is usually in spring. Koi are a highly adaptable fish and can be farmed almost everywhere in most parts of China.

Koi have a broad diet and are omnivorous fish. Their breeding is similar to that of common carp and they can reproduce naturally. However, in order to obtain more high-quality varieties, artificial breeding is often used.

Breeding work can begin when the water temperature is above 16°C. When carrying out natural breeding, spawning nests should be prepared, usually using water plants, pine needles, palm fiber sheets, nylon ropes (threads), etc. that have been disinfected with potassium permanganate solution, mainly to allow the eggs to attach evenly. Tie the above objects into small bundles and hang them on the water surface of the pond.

⟧ The ratio of broodstock is generally one female to two males. If there are many broodstock used for breeding, 1:1 is also acceptable. Koi are most likely to spawn on the morning of thundery weather. With artificial water flushing stimulation, the effect will be even better.
