There are many reasons why the purpose of breeding goldfish is to breed goldfish. The most common reason is that when the raised goldfish suddenly has a pile of eggs, it is based on curiosity and the eggs are eaten by the big fish. Thoughts. Under such circumstances, due to unpreparedness, there is often a situation of confusion and overwhelming. However, if there is a plan and purposeful breeding, it is better. What is a planned and purposeful breeding?

The discrimination of male and female talks about the breeding of goldfish first and foremost. Mature goldfish are better identified when males mature. On the front of the pectoral fin, there is a chasing star appearing, which is more obvious in the estrus period. There will also be star-chasing in the large male fish's gill cover. Among them, the type of long-fin type is most obvious (such as gilt, lion, etc.) and it is easy to distinguish. . The shorter fins are less obvious, especially when they are fish. When the fish aren't fully mature yet, the starchaser looks like nothing, and it hurts to check it. In the long fin type, Blister is the most difficult to distinguish.
When goldfish are small or difficult to distinguish from chasing stars, it is better to look at the vent holes. From the side of male fish vent hole, no milk convex can be seen; while the female milk convex is more obvious. That is to say, males can't see tiny bumps, while females can see a small bump. If viewed from the rear, the male fish has a narrower excretory hole, while the female has a more round excretory hole. It is said that the male and female of the fish are not easy to distinguish. It's still very easy to see what happens. There is also a round spherical pearl scales, the stomach is swollen, the vents have been deformed, so it is difficult to distinguish between male and female.
As for the size of the figure, whether the abdomen is rounded and the vividness of the color, the male and female are different, but they are not immutable. However, the fins of the long-fin males are significantly longer and are well-defined. Therefore, long-fin males and females can be distinguished by this feature.
The spawning period and the signs before spawning are spawned almost every year in Taiwan, and the fertility period is two months before and after February (that is, from December to April), and one month before and after (November to May). Month) is also common. Although spawning is less frequent in other months, it is not surprising if you are spawning! When the star catcher of the male fish is particularly noticeable, when the belly is squeezed, white semen flows out. This means that you are not going to play the game, you are going to be stunned, you're going to be sloppy, you're gonna write the grasshopper, you're gonna write the ball, and the abdomen is full and soft, which means everything is ready to go as soon as the time arrives. , you can spawn immediately. What is the timing of spawning? What is common is when the new water is changed, before and after the cold flow (when the temperature changes substantially), when the environment is changed, and when the male and female fish are newly mixed, the most special is the environment. In bad times, they spawn. In short, when it comes to stimulation, it is easy to lay eggs.
The focus of breeding - "spawning", after the successful hatching of eggs, how can the owners take care of the walls so that they can use the sands? Let's explore with us the process of breeding goldfish!
If the egg is picked by the goldfish artificially, the fish will be very tired. In particular, females are often physically exhausted and are easily injured. In addition, if you do not have time to remove the eggs before noon because of work, the eggs will be eaten by the fish that produced the eggs. Therefore, artificial spawning can be considered. There are many ways to artificially lay eggs, mainly dry, wet, and net.
The hatching of eggs is covered with nets or plates of fertilized eggs. After about 5-10 minutes, they can be transferred into a container filled with clean water and wait for hatching.
The development of the fertilized eggs and the speed of incubation are closely related to temperature, sunshine, and water quality. Therefore, it is important to keep the water clean, proper lighting and optimum temperature. The best temperature for hatching is 20°C, and hatching takes about 4-5 days. Therefore, I like to hatch in the cold, because it can use a warmer, keep the water temperature at 20 °C; and the temperature between 20-25 °C, are also considered good; if the temperature is higher than 25 °C, it will cause hatching Too fast; and if the temperature is lower than 20 °C, it will cause hatching too slowly. Both will lead to reduced larvae's yield...
