Lanshou goldfish will not die without artificial ovulation, because they can ovulate by themselves. A mature Lanshou can discharge its eggs by itself in the breeding season. Even if there are no males to mate, they will discharge their eggs by themselves, but they will not become fertilized eggs. In addition, artificial ovulation will cause certain harm to their bodies, so breeders should try not to choose artificial ovulation.

To artificially ovulate Lanshou, breeders need to wait for them to mature first, and then they will reproduce from May to June every year. Before breeding, breeders should choose suitable parent fish and put them in a separate container. Then prepare a water plate to hold the discharged fish eggs. When ovulating, the breeder can hold the female fish with one hand first, and then gently press the abdomen of the fish with the thumb of the other hand, so that the eggs can be easily discharged.

If the breeder wants to breed artificially, he should immediately select a mature male fish, then gently squeeze their drainage holes with his hand, and discharge their sperm into the plate, so that the fish eggs and sperm will combine and become fertilized eggs. This way can improve the fertilization rate and increase their reproduction number.
