of koi carp 1. Artificial breeding method: Artificial breeding is to fish out the female fish when the female and male fish begin to chase and spawn, dry the water on the fish body with a towel, then grasp the koi carp by hand, gently press the abdomen, and squeeze the eggs into the plate prepared in advance. Then fish out the male fish, repeat the above steps, take out the sperm of the male fish, and put it in a small plate with fish eggs. Gently stir the feathers evenly, and then quickly sprinkle them on the fish nest in the water. Generally, they can be hatched in 4-7 days.
2. Natural breeding: breeders should first prepare fish nests, such as aquatic plants, pine leaves, nylon ropes, etc., as long as the fish eggs can be evenly attached to them. Secondly, the water temperature should be kept above 18 degrees, and finally the parent fish should be put in according to the ratio of female 1:2. After they breed naturally, they should be fished out as soon as possible to prevent them from eating the eggs as food.
the eggs of Koi after breeding? The eggs of Koi after breeding can be soaked in malachite green solution for five minutes to avoid the occurrence of Saprolegnia. Then fish them into clean water and turn on the oxygen pump and circulation system, because the slight current can help the eggs hatch. Also keep the water temperature at 22-25 degrees, the higher the temperature, the faster the eggs hatch. Generally, koi can hatch small fish in 3-7 days after breeding, and the fry can be fed after swimming.
