How to distinguish koi fish from other fish?

How to appreciate koi fish: First, body shape is good. When appreciating koi fish, body shape is highly valued. Without a good figure, no matter how good the pattern is, it will not be a high-quality koi fish. Although a good graphic sounds simple, its knowledge is actually very profound. I believe anyone with a little appreciation experience can find the best figure among a group of koi fish. The problem is that this koi fish, which is considered as the best figure, may be the worst one if compared with another group of koi fish. Therefore, it takes considerable experience to identify it without comparison. So how to identify it? From beginning to end, of course. The first thing to look at is the distance between its eyes. Whether the distance between the eyes is wide enough, koi fish, whose eyes are far apart, usually grows bigger; Then see if the root of pectoral fin is long enough to the snout, that is, the length of the head; Let's see if the distance between eyes and mouth is too short. If this part is too short, it will form a triangular head, which is not ideal. Next, kiss a little thicker. It's hard for koi fish to grow into a big fish if he kisses thin. The beard can't be too small, but when koi fish is infected by parasites, his beard is often damaged by vibration or friction, and the regenerated beard is also short, so this part is for reference only. Head and tail should pay attention to whether the cheeks on both sides are even and full, and the top of the head must be full; Koi fish with a flat head is not ideal. Next is pectoral fin, which has different shapes due to different systems. In principle, it is not good for pectoral fins to be too small, too sharp or triangular. In addition, the pectoral fin moves forward too much when swimming, which seems to be very difficult, indicating that there may be something wrong with the health of this tail koi fish. The body shape from pectoral fin to caudal stalk must be smooth, without sudden uplift or depression. The tail handle is thick, and it can also be seen from the tail handle whether the physique and development of a tail fish are good. From top to bottom, the fish must have an appropriate width and an appropriate side height. Although the height of lateral height will vary from system to system, its highest point should be in front of dorsal fin. If the highest point of the side height is in the middle of the dorsal fin, it is not acceptable to look like a hunchback. The body shape is finally the caudal fin part. Although the caudal fin is very thin, it still gives people a deep and powerful feeling, preferably not too long, and the forked depression of the caudal fin is not too deep. In a word, a good figure is the foundation of high-quality koi fish, and only with a good foundation can we hope to cultivate high-quality koi fish.

2. As an ornamental fish, high-quality colored koi fish's body color is a very important viewing point, and the quality of these body colors naturally becomes an important criterion for appreciating high-quality koi fish. How to evaluate the quality of color? First of all, the color is pure, thick and oily. If the color is impure and mottled, it is not a high-quality color; But if the color is thin and light, it is difficult to show its gorgeous color, so the color quality is very poor. Koi fish of this color must not be a high-quality koi fish; Although some spots are pure and thick in color, those that reveal the background color in the spots and form the so-called "skylight" can't be good colors, which are not the colors that high-quality koi fish should have. If the color is oily, it will show excellent luster. If the color is thicker and oily, it will show its gorgeous color. If the color is dull, it will not show its gorgeous color, so it is not the color quality that high-quality koi fish should have. Secondly, due to the different lineages and strains of koi fish, the depth and thickness of its color are also different. For example, in the red and white category, the red and white of the big solar system, its erythema is orange, which is more bright and bright; However, the red and white of the Xianzhu system, its erythema is thicker and deeper, which appears darker; Another example is Nana Ogawa red and white, whose erythema is thick, delicate and oily. Like shiny gold, Zhang Fenjin is light in color and golden in color. The chrysanthemum is thick and dark, orange-yellow; Another example is the white spot on koi fish, which is a color in many koi fish varieties and is called white. Moreover, white is also a color that has attracted more attention at the National Tasting and World Tasting in Japan in recent years, and its color quality directly affects its score and award-winning ranking. High-quality white spots are fine, white and free from noise, while low-quality white spots are grayish black or yellow, which makes the color quality of white spots low, which is not the color quality that high-grade koi fish should have. Therefore, when we appreciate the color quality of koi fish, we should identify it according to its specific pedigree and strain. 3. koi fish with symmetrical patterns is an ornamental fish, and the distribution of patterns will directly affect its ornamental effect. Appreciating the decorative patterns in koi fish is relatively simple. Even if a beginner wants to pick out koi fish whose patterns are evenly distributed among a group of koi fish, it is relatively easy, or it can be said that it is easy to get started, but it still needs some efforts to really master it. So what kind of pattern distribution is an excellent pattern? When we appreciate the patterns of koi fish, we should first look at the whole. The overall pattern distribution should be symmetrical, that is, the pattern distribution should not be concentrated in one place or one side, while there are no stripes or too few stripes in other places. This model is not a good model. In addition to the symmetrical distribution of the overall pattern, there should also be characteristics in the key points of decoration to show its personality characteristics. For example, the patterns on the head and shoulders must be changed, especially the patterns on the shoulders must be broken, which is commonly known as "shoulder crack". If there is no shoulder crack, the decoration focus will not change, then the pattern will be dull and tasteless, lacking fine products, which can be said to be not a good pattern. Besides the head and shoulders, the pattern on the tail handle is also very important. A koi fish with evenly distributed patterns, if there are no good ending spots on the tail beans, is equivalent to no ending, which is not perfect. In addition to the pattern distribution on the back, it should also extend to the abdomen, which is commonly known as "belly rolling". Koi fish's belly-rolling pattern is full of strength, which makes koi fish show a strong sense of beauty. In the appreciation of patterns, in addition to the overall pattern distribution, we should also appreciate them according to their variety characteristics. Such as Dazheng tricolor, in addition to the distribution of erythema, the distribution of ink spots is also very important. Ink spots should be mainly distributed in the first half, if distributed on erythema, it is not a good speckle position; If it is distributed on white spots, which is commonly known as "cave ink", this is a very good position. These acupoint inks often get higher scores in the evaluation. Another example is Dante. Whether it is red or white, whether it is Zheng Da, Zhao He or Zhang Fen Dante, the plaque on the top of the head should be located in the center of the head, not in front of the kiss, not beyond the skull, and not beyond the sides of the eyes. This is a good Dante, otherwise it will be a bad model, and its quality will be greatly reduced. At present, in the commodity market, there are still some people who repair the spots manually, that is, remove the excess parts of the spots by manual means; Or use the method of skin grafting to add color spots in the position where the color spots are not enough, so as to achieve the effect of symmetrical distribution of color spots. However, I think appreciating the natural beauty will be smoother than artificial beauty, and at the same time, the spots removed manually will grow back after a period of time. It is only to deceive buyers in the transaction process and should not be advocated.

Fourth, good swimming posture koi fish is a "swimming work of art", and its swimming posture is bound to become one of the conditions for appreciation. Whether the swimming posture is graceful and smooth and powerful is a standard of appreciation. If koi fish swims in the water, his body is crooked, like a snake, or he often swims sideways, then this swimming posture is unqualified. Whether its pectoral fin is strong when paddling, and whether it is weak when stopping; Whether the swinging motion of the tail handle is moderate, the motion is too small, and it looks weak, which does not reflect the strong side of koi fish. If the action is too big, it seems exaggerated and uncoordinated. If you often lie under the bed, it is possible that koi fish is not normal, so you should check if he is sick. V. Huge Genre When appreciating koi fish, the size of genre is not an indispensable condition, but in actual appreciation, koi fish with huge genre often attracts people's attention, which will better reflect koi fish's vigorous swimming posture. If you have the above four advantages, plus a huge genre, it can better reflect its advantages as a "swimming art" and look more relaxed and happy. Therefore, farmers in koi fish farms and koi fish enthusiasts all aim at koi fish. koi fish has a large style and specifications, and it is proud to be able to raise koi fish with the above four conditions and grow to more than one meter.

When you enjoy and taste the favorite carp by the pool in koi fish, you will feel a lot of unspeakable joy, and you can enjoy happiness that you can't enjoy in other places. Let these "swimming artworks" and "living gems in water" accompany you through every pause.
