Three minutes to teach you to choose and buy koi, Zhaohe tricolor brocade carp seedling screening skills

It is very important that the fry of Showa tricolor should be selected for the first time within 3-15 days of birth. In the end, the seedlings that grow into Zhaohe tricolor are gray-black, and the gray-black seedlings grow weaker and fewer, while other red, white or red-and-white seedlings grow faster. The black seedlings of Zhaohe tricolor grow slowly and will get weaker and weaker and eventually die, so the earlier the first selection, the more likely it is to get more Zhaohe tricolor.

In the first selection, pick out the black seedlings, and the white or orange seedlings can be eliminated. If it is not selected in time, by the time it is older, the tail of Zhao and tricolor may be gone. The stocking density should also be lower, usually less than half the density of red and white fry, and feed is relatively sufficient to ensure its rapid growth and survival.

The second selection of tricolor and tricolor is later than red and white and Dazheng tricolor, about 60 days. At this time, the Zhaohe trichromatic body is dark, and there are almost no white markings. To observe carefully, those with dark orange spots under the black spots should stay, while those with black and yellow markings may be gossip writing. If the pattern distribution is reasonable, you can stay, otherwise it will be eliminated. But the white markings appear relatively late, nearly a year old is not even, as long as you see a faint gray spot under the white, and the distribution is reasonable, you should stay.

For koi under the age of three, first of all, the quality begins to show, and there are very few trimming parts when the selection can be made. The important thing is to judge according to the nature of their parent fish and what they will become when they grow up. This is important not only when choosing a fish of age, but also for carps that grow up at the age of two and three.

If you are about three years old, the pattern may be good when you buy it at the age of three, but at the age of three, due to the change of pattern and the disappearance or increase of color spots, it is often difficult to stay and continue to develop big fish. At the age of three, it is a good way to observe the brother carp of the same fetus, to understand their situation at that time, and to select them according to their changes.

When buying koi, it is often not easy to see the situation of parent carp. It is best to observe other brother carps of the same birth and make a comparison, which is a good way to understand their quality.
