pet.net has learned that the breeding season of golden fish is between April and May each year.

Breeding goldfish must first choose a good species. Before selecting species, first observe the star chasing of the fish to identify males and females. Star chasing refers to the red bumps the size of sesame on the two gill caps, dorsal fins and the top of the front row of the male fish. There is no star chasing for the male fish.

For breeding, choose a species of strong, species pure and good body shape, and the same species should be selected A female fish with similar traits is matched with a male fish. If there are two female fish, it is matched with two male fish, and so on. Fertilization of goldfish is carried out in vitro. When a female fish ovulates, a male fish must immediately follow Sperm is discharged from the top of the tank, so that the fertilization process can be completed, otherwise no small fish will be produced.

After selecting the species, choose to put a bunch of anchovies in the fish tank. Anchovies, use other aquatic plants, or even replace old brown silk and hemp silk. Then put the seedlings together, and other unrelated goldfish need to be moved to other fish tanks.

After seeding the fish, the females must be caught immediately and placed in other fish tanks to be raised separately. In the tank with male fish, it must be replaced with new water immediately, otherwise the water quality will be affected. The rotten smell will cause the fish to die.

Whether it is a new fish that has been sowing for the first time or an old fish that has been sowing for many years, it is generally necessary to sow three times during the breeding period. The second time to spread the seeds, the interval is about a week. The quality of the fish roe is generally better when the second time is spread.

After the fish roe is spread, it should be immediately removed with the anchovy grass. Take it out of the tank and put it in another clean water tank. But the tank must be bigger, because hundreds of young fish hatched will live in this tank for a period of time. The tank should be placed in a ventilated and sunny place. 23 After a few days, the transparency of the roe gradually decreases, and a black spot will appear at the same time, which is the head of the juvenile; after 35 days, the black spot expands into a circle, which is the body of the juvenile; after a while, a small goldfish will hatch It became

The little goldfish was very tiny when it hatched. It didn't eat for the first few days and was attached to the bottom of the tank, the walls of the tank and the original anchovies. At this point Don't disturb it and don't rush to take out the anchovy in the tank.

When the fish is hatching, it will be beneficial to the growth of the roe when it is rained or the weather is particularly stuffy and humid. , often the roe remains unchanged after a week, and even some roes will grow mold or rot. At this time, you don't have to worry, just move the fish tank to a ventilated place, and the little goldfish will still hatch after a longer time. The only thing that comes out is a little less.

The method of feeding young fish is the same as feeding big fish. Feed the fish some light yellow little water fleas (commonly known as egg yolk fish worms) or boiled egg yolks. You can also take some live fish and worms and put them in the hatching fish tank before the little goldfish are born.
