The method of selecting koi in that year, the choice of body size and color of koi

When selecting red and white, first choose the one with large stripes on the head. First of all, in the small fish's head to see the edge of erythema, to show the white mouth, or there are broken markings behind the mouth, this should be very clear. If you can see that kind of erythema, it will have the future. Don't cover your eyes with erythema. See both eyes, just like erythema on top of your head. This can be seen clearly in the small fish stage, and there should be a red thickness. The head markings are loose and without personality, which can be eliminated. The second is shoulder fissure, that is to say, erythema must be cracked behind the skull, even if there are very few minor fractures, otherwise it will not be the embryo of a high-quality fish.

In the selection of parent fish, the color quality and pattern are preferred, while compared with the pattern, color quality should be given more priority, preferably 80-90 cm large fish.

It is generally difficult to distinguish between 3 and 10 centimeters of small fish. if it is more than 15 centimeters, it will be a little easier. Specifically, the species with red spots, in 3-10 centimeters of fish fry, red spots are not very obvious, some will also have color infiltration. Poor quality fish, the erythema will also change, there will be a retreat, especially in the second half of the erythema, often after growing to a certain extent, leaving a white background, becoming a secondary fish. Small fish with blurred erythema are of poor quality. no matter how big they are, they should not be left to continue to raise, but should be eliminated at the right time.

For fish of the same birth who grow up under the same conditions, a darker color is better than a lighter color.

As for the old fish, it is more difficult to distinguish and judge the quality, but we must look at the glossiness of the erythema. The erythema of this kind of silk general bright color is not easy to fade to belong to the high quality; the surface is rough, the color is uneven, and there is no certain thickness. This kind of erythema is also easy to retreat, and the fish of this quality should be eliminated.
