How do you know the koi is going to give birth? What should you pay attention to when laying eggs?

To determine whether a koi is ready to give birth, you can observe whether there are small white spots on the fins of male koi. White spots appear on the fins of male koi carp entering the breeding season, indicating that the koi carp is ready to start breeding. In this case, the breeder will begin to prepare the tools for laying eggs. Prepare a separate container and put the Pteris multifida or hemp in the container. Koi reproduction is a process in which the female first discharges eggs and the male then discharges semen to complete fertilization in the water.

Koi

usually breed in April and May, during which time the male and female will chase each other all the time. And the male fish will appear on the fin or gill cover of several small white spots, which are commonly known as "chasing stars". Therefore, the discovery of "chasing stars" on the fins of male fish means that they are about to reproduce and give birth.

2. What

should we pay attention to when laying eggs? 1. Before laying eggs, we should prepare the container for laying eggs. It is better to put a bunch of Pteris multifida in the container. If there is no Pteris multifida, we can use other aquatic plants or old hemp instead.

2. After the female fish lays eggs, it needs to be fished out immediately and kept separately in a new container.

3. If the female fish ovulates, the male fish must ovulate sperm so that it can become a fertilized egg. If the male fish does not release sperm after ovulation, artificial ejaculation can be tried. Gently press the belly of the male fish with your thumb, and it will discharge sperm.

4. After the eggs are fertilized, they can wait for the fertilized eggs to hatch. In rainy weather, fertilized eggs will be more difficult to hatch, and some will become moldy and hairy. Keepers can move the tank to a ventilated place, which can reduce the growth of mildew. Although small fish can be hatched in rainy days, the number of successful hatchings will be very small, so it is better to choose sunny weather when breeding.
