with the spawning of domestic goldfish? After the spawning of domestic goldfish, if the breeder wants them to reproduce, he should choose several male fish that have reached the breeding period to stimulate them to ejaculate, so that the eggs become fertilized eggs. After the eggs become fertilized, the breeder needs to prepare a suitable environment to incubate them.
If the breeder does not want the goldfish to reproduce, the eggs can be fished out immediately after the goldfish spawns, or the parent fish can eat the eggs to help them recover. If there are fish eggs sticking to the wall or bottom of the tank when the goldfish throws eggs, the breeder needs to transfer the fish in the tank first, then clean up the fish eggs on the tank wall with a brush, and finally disinfect the tank with potassium permanganate solution before it can be used again.
the eggs of domestic goldfish? The hatching method of goldfish is relatively simple. After fertilization, the eggs will become transparent or yellow, and there will be a small black spot in the middle. At this time, the breeder only needs to control the water temperature at 30 C and keep the PH value between 7.5 and 8.0. During the incubation period, breeders should not change water to avoid fluctuations in the environment, but also maintain adequate oxygen, which can speed up the incubation of fertilized eggs. When the eggs hatch, the breeder should close the filter to avoid the filter sucking the eggs away.
