1, the choice of parent fish: want to breed success rate is high, want to choose good parent fish above all. Specifically, we should try our best to choose goldfish with obvious species characteristics, healthy body, lively swimming and suitable age as parent fish. When choosing, we should pay special attention to the proportion of male and female, and try to keep it at 1:2 or 1:3.
2. Separate feeding: After the parent fish is selected, they need to be raised separately, and the water temperature should be controlled between 18 and 25 degrees. In the breeding season, there will be male fish chasing female fish. In a few days, if the male puts his head on the female's abdomen, it means that they are about to give birth.
3. Put them in the fish nest: When they are about to give birth, they need to be put in the fish nest. On the second day of nesting, the female goldfish may lay eggs on the top of the nest, and then the male goldfish will release semen, which will combine to produce fertilized eggs.
4. Hatching: After the sperm and the fish eggs are combined, the inseminated fish eggs need to be taken out and then placed in a fish basin. The water temperature can be controlled between 17-20 degrees. After about seven days of incubation, the young fish can hatch. In about three or four days, they can be fed.
Goldfish breeding generally occurs in the spring. However, the specific breeding time is also different, which is affected by many factors. For example, regional factors have a great impact on breeding time. In the area north of the Yangtze River, breeding is usually in May or June; If it is in the area south of the Yangtze River, it may be in February or March.
