Natural Breeding: After the fresh water is exchanged every day, the males will chase the females desperately, and they will use their heads and kisses to hit the abdomen of the females or the anal of the caudal fins. Even a few males chase after a female. Sometimes the female pushes the pool (cylinder) wall directly. At this time, the artificial fish nest is put down. Then the fish often gather around the fish nest. Some male fish also use the head and put the artificial fish nest to hit a depression. The female arranges the “delivery roomâ€. At this time, it shows that the broodstock is going to have children. Wait until the water temperature can continue to maintain around 15-20 °C, the mature broodstock will have a strong spawning performance, this time, you can select the female and male fish fishing spawning a new spawning pool of isothermal (Cylinder) At the same time, put artificial fish nests. At this point, the female encounters the chasing of the opposite sex and the stimulation of new water will secrete an estrogen from the genital hole (anus), tempting the male fish, causing the male fish to chase the female fish desperately. In the abdomen and anus, it is half an hour fast, and when it is slow, the females are exhausted and swimming slowly, but the male fish is still holding on to the female with a strong drive. The top of the fish struck near the fish nest. At this time, the females migrated to the center of the fish nest. The male fish tracked in. In an instant, the females trembled and the tail flung, ie, the transparent pale yellow eggs were discharged and evenly distributed. Spread and stick to the nest. At the same time, the male fish also vibrate at the tail, discharges white semen to swim in the water, encounters eggs, and the sperm is drilled into the egg to complete the fertilization process. This process is called in vitro fertilization, or self-coordinated. Artificial breeding: In recent years, goldfish farms and goldfish enthusiasts around the world have begun to change the situation in which goldfish can only naturally mate after breeding for thousands of years. Artificial insemination has been adopted to increase the reproductive ability and fertilization rate of goldfish. Experiments show that the fertilization rate of artificially inseminated fish eggs is 20% to 30% higher than natural insemination. In order to improve and preserve the quality of goldfish varieties, it is a good idea to use artificial insemination to cultivate new varieties with purposeful breeding. There are two specific methods: (1) Water fertilization method The male fish in the pool are seen to be persistent in each breeding season. Reluctantly chasing female fish, when the female has a few eggs discharged, the male and female goldfish can be immediately fished into the water basin, and then the female fish is removed from the water in one hand, and the female is gently squeezed with the thumb. From the pectoral fins to the abdomen, let the eggs be evenly discharged into the previously sterilized shallow enamel plates. Then quickly use the same method to gently squeeze the abdomen of the male so that the semen can quickly flow into the egg dish. The other hand can take a little isothermal. The new water gently pours the semen into the egg tray, and then gently mix the semen and the egg with a clean brush or feather, and mix thoroughly and quickly fertilize. About 15 minutes later, the eggs of the fertilized eggs were slowly poured onto the fish nests in the hatchery (cylinder) and allowed to hatch. (II) Intra-water fertilization Whenever we see male fish chasing females and seeing a few granules expelled, we can use a water basin or a small open cylinder to hold 1/3 to 1/2 of the new water. Bring the female and male parentfish to the basin or the small open jar. Put a layer of artificial fish or brown silk on the bottom of the basin. Hold both the female and the male fish with their hands so that their reproductive pores are relatively large. With your thumb gently squeezing the male abdomen, see milky white semen spilling out. Use the same method to squeeze out the eggs in the female's abdomen. Shake the two hands gently in the water to make the eggs evenly fall into the basin. In the artificial fish nest at the bottom of the tank, the egg and sperm are quickly fertilized in water, and the egg is transparent and turned into a beige fertilized egg. Because the in-water fertilization method does not separate from water, the damage to the broodstock is slightly less than that of the insemination method of fertilization. The egg fertility of fertilization is strong, and it can quickly attach to the artificial fish nest. It is easy to change water, and it is easy to operate. The fertilization rate is not inferior to Water fertilization method. The benefits of artificial insemination are many: 1. According to people's wishes, it is possible to carry out cross-breeding of the same breed of broodstock reared in different breeds or in two places, which is conducive to the cultivation of new varieties and the improvement of the characteristics of the original breed. 2. It is beneficial to households of fish farmers and small fish farms where there is no shortage of tanks, and there is no proper spawning tank (cylinder). 3. In the case of less male fish or unhealthy male fish, breeding can also be carried out without being trapped by poor spawning conditions, which compensates for the lack of natural insemination and increases the utilization rate of sperm cells and the fertilization rate of fish eggs. 4. Artificial insemination is simple and easy to use. It can reduce the occurrence of female deaths due to childbirth and maintain the breeding season. It can arrange and master goldfish spawning time. 5. The artificial insemination method has a short spawning time and can improve the utilization of the pool (cylinder).
