Goldfish can be natural breeding, but not as good as the effect of artificial breeding, at home can give it artificial breeding. The first step in goldfish reproduction is to choose the right parent fish. First of all, the parent fish should be healthy, and the body shape is balanced, not too fat or too thin. If we consider the ornamental problems of small fish after reproduction, it is better to use goldfish with very obvious characteristics as parent fish. In addition, when choosing male fish, we also need to pay attention to the state of semen. The semen of some male fish is not easy to disperse or yellow, so this male fish should not be used. It is better to choose some male fish whose semen is white and easy to disperse as parent fish.
After choosing the parent fish, the next step is to give them the steps of artificial insemination. You can hold the male in one hand and the female in the other and squeeze out their eggs and sperm at the same time. Semen is relatively easy to disperse, so we should pay attention to timely extrusion of fish eggs into semen, so that it can combine with sperm.
After artificial insemination, the reproduction of goldfish is not over, because there are still unfertilized eggs. So, the next step is to pick out the eggs that have been fertilized. Specifically, you can wait 24 hours and then observe the state of the eggs. The transparent ones had been inseminated, and the whitish ones had not. Pick out the transparent fertilized eggs, clean them, put them in water of 17-20 degrees, and wait for them to hatch naturally.
