The method of selecting koi in that year, and the skills of beginners in buying koi

When choosing and purchasing, you should first pay attention to not buying diseased or deformed fish, especially the following points:

1. Whether to act together with other fish.

2. Whether or not to leave the group and stand still.

3. With or without Gill disease and shortness of breath.

4. Don't make the scarlet pattern small, because the markings will shrink and may disappear when you grow up.

5. The margin of the scarlet pattern is blurred, because the scarlet spot may disappear, or the erythema may be scattered or dotted.

6, the right amount of erythema and ink spots should not be selected, because it is possible to reduce and disappear the danger of red and ink spots.

The method of selecting and purchasing larvae

Fish larvae only refer to the small fish grown by 2cm. The important thing is to buy the larvae produced by excellent species of carp, and it is best to see the parent fish before buying it. Usually people who buy fish larvae want to get good koi from them, but when you buy a large batch of thousands of fish larvae, the future selection work is very important and should not be left unchecked. For the first time, white landless, naked landless, deformity, deformation and so on were eliminated. The second time, those with poor patterns are eliminated. All in all, raising larvae is not just about feeding feed, but also requires patient screening in order to produce good varieties.

Juvenile fish selection and purchase method

The big 5~10cm fish are called juvenile fish. Most of the young fish are enthusiasts, and they usually choose a hundred strips to raise, hoping to breed three or five high-quality carps. Enthusiasts of this type usually go to the fish farm to select more than 10 juveniles from August to September each year, that is, the second and third screening of the fish farm. If you choose and buy red and white, Dazheng tricolor and Zhaohe tricolor, you should choose the red markings with good location, clear edges and strong colors. It is best not to choose larger and more black spots, because black spots will concentrate and become larger with the growth of love carp, and then easily fade and disperse, so it is better to choose those who can vaguely see black spots on a white background.

In addition to pay attention to the pattern, the figure should not be too thin, deformed, deformed, traumatic or sick fish are absolutely not allowed to buy. If you can, you'd better take a look at the breeding carp. If the quality of the breeding carp is good, then the juvenile fish will be more likely to get the inheritance of good lineage. In addition, the dorsal fin of koi can also be observed, and the dorsal fin of koi with good quality is white. In addition, it depends on whether the juvenile fish can grow into a large fish. At this time, the head can be observed. The bone of the head is large and round, which is larger than other juvenile fish, so it is easier to grow. Piguang carp should choose those with bright head and pectoral fins.

Although we have carefully selected juvenile fish for breeding, once variations such as discoloration or deformation are found, they must be eliminated as soon as possible in order to reduce the number of juveniles. This can not only save feed, but also reduce water pollution and increase dissolved oxygen.

Selection and purchase of juvenile fish

The so-called koi juvenile fish refers to the small fish grown by 15~35cm. There are great differences in the appearance of patterns between young fish and adult fish. for example, the beautiful tricolor patterns of young fish often lose their charm because of the large distance between the markings; and sometimes the large patterns on the body surface of young fish do not seem to be in harmony. However, once you grow into a big fish, add an appropriate white background, but become very beautiful.

German carp are also more beautiful in young fish. German carps are characterized by changes in patterns made up of large scales and distinct markings on scaleless skin, so German carps are very beautiful and gorgeous when they are young. Once grown into an adult fish, because the pattern is too bright, there is a lack of stability in the feeling. Most German carps are based on mirror carp, so the two rows of large scales on the back and in the center of the abdomen are arranged neatly and without extra scales.

It is difficult to tell a young fish from a female. Generally speaking, during this period, male carps grow fast, with thick spots and bright edges, but when they get older, females are more likely to grow up and fuller than males. So it often happens that the young fish who have won the evaluation will have little chance of winning when they reach adulthood.
