Koi breeding method, how to hatch after breeding

There are two methods of breeding koi: artificial breeding and natural breeding. Artificial breeding is to take out the female fish when the male and female fish are in estrus, press its abdomen gently with the thumb, squeeze out the eggs, and put them in a small plate. Then, use the same method to obtain the sperm of the male fish, stir it evenly with a feather, and put it in the fish nest with the eggs to hatch. Natural breeding is to prepare the fish nest, put the parent fish in the ratio of 1:2 between male and female, and let them breed on their own.

1. Artificial breeding method: Artificial breeding is to take out the female fish when the female and male fish start chasing and are about to lay eggs. Use a towel to wipe the water off the fish body, then grab the koi with your hands, gently press the abdomen, and squeeze the eggs into the prepared plate. Then take out the male fish, repeat the above steps, take out the sperm of the male fish, and put it in the small plate containing the eggs. Use a feather to gently stir it evenly, and then quickly sprinkle it on the fish nest in the water. Generally, it will hatch in 4-7 days.

2. Natural reproduction: The breeder must first prepare a fish nest. You can use water plants, pine needles, nylon ropes, etc., as long as the eggs can be evenly attached to them. Secondly, keep the water temperature above 18 degrees, and finally put the broodstock in a ratio of 1:2 for females. After they reproduce naturally, they should be removed as soon as possible to prevent them from eating the eggs as food.

2. How to hatch koi eggs after breeding? After breeding, you can soak the eggs in malachite green solution for five minutes to prevent water mold from forming on the eggs. Then, put them in clean water and turn on the oxygen pump and circulation system, because a slight water flow can help the eggs hatch. The water temperature should also be kept at 22-25 degrees. The higher the temperature, the faster the eggs hatch. Generally, small fish can be hatched 3-7 days after breeding, and they can be fed after they can swim.
