In the fertilized egg cell, the egg membrane quickly swells, and the egg becomes slightly yellow and slightly transparent and enters the embryonic development stage of the goldfish. If the egg cells become opaque and then gradually white, this is due to unfertilized, this egg cell will not hatch. First, the factors affecting hatching The length of hatching time and the rate of emergence of fertilized eggs have a close relationship with the external environmental conditions. Among them, the effect of water temperature is the most significant. Goldfish incubation temperature requirements in the range of 18 ~ 30 °C, the best temperature is 20 ~ 22 °C, in this temperature conditions fertilized eggs after 3 to 4 days of incubation can be stripping. Rapid development of water temperature, low water temperature, slow development, rapid and slow embryo development are unfavorable, easy to produce more deformed deformed fish, will reduce the survival rate, in the embryonic development process, if there is a sudden change in temperature , it will seriously affect the embryonic development of goldfish and there will be a lot of death. In addition to the appropriate water temperature, high dissolved oxygen and appropriate pH are also essential external conditions for the smooth development of the embryo. Second, the hatching process should pay attention to issues Fertilized eggs should be transferred within 1-2 hours after hatching hatching pool and control the temperature difference is less than 2 °C; Do not overturn the fish's nest and ensure that the nest and fertilized egg are immersed in the water during incubation; After the disappearance of the yolk sac of the larvae, the fry can be removed after 1-2 days after all the fry are able to autonomously swim and swim (called “off the nestâ€); During the incubation process, the water should not be changed, nor should the water be agitated so as not to affect the development of the embryo and cause abnormal development or death of the fry.
