How to identify the authenticity of koi fish, and whether the color changing koi fish is real or fak

Is koi real or fake? For the first time, I heard that koi fish were true or false. Koi refers to the colored carp, which is a prerequisite for koi. The distinction between koi fish mainly depends on factors such as bloodline, color, body type, etc., and there is no difference between true and false, as long as it is good or bad.

The difference between real and fake koi is as follows:1. The size of the koi is similar to that of the carp, and the scales of the body will be different according to the species, most of which will be more colorful.

2. Looking at the core of the beard shirt, the koi have a beard, while the fake koi are all crucian carp and have no beard.

3. Looking at the tail, the tail of the koi carp is still short and small, while the tail of the crucian carp will be relatively wide.

4. Look**, the price of koi's **, adult fish will be much higher than that of crucian carp, and it will be slightly different because of different varieties.

The basic criterion for the appreciation of red and white koi1. Red and white must be distinct.

2. The boundary around the markings is clear.

3. The eyes and fins should not be crimson or dyed red.

4. The markings should not appear below half of the body height (lower abdomen).

5. The markings should be cut off at the end of the nose and the root of the tail.

Color-changing koi fish are generally fake.

It is created by the merchant through laser coloring, pigment dyeing, surgical color removal, pigment feeding and other methods, and the basic introduction of koi is as follows: Appearance characteristics: Koi fish are physical, and the colors on the body crack mold are bright and rich, and the colors include one to several colors, including white, black, blue, yellow, orange, red, etc.

Growth habits: Koi fish are omnivorous fish, mild in nature, like to swim in groups, easy to raise, and have strong adaptability to water temperature.

Four Seasons Management:

The management methods of koi fish vary depending on the season.

In spring, the weather is warm and cold, the koi begin to recover from hibernation, and the feeding is transferred from indoor to outdoor, but special attention should be paid to the sudden cooling, and the film should be covered in time to keep the water temperature stable; The bait is mainly plant-based bait, and the amount of bait gradually increases from less to facilitate the digestion and absorption of koi.

In summer, when the weather is hot and hot, it is necessary to cover with a plastic shading net to prevent direct sunlight, so that the sunlight illumination is reduced from 8000 12000 lux to 5500 5800 lux.

In autumn, the weather is less rainy and more sunny, and the water temperature drops significantly, which is the most suitable for the growth of koi fish, which can increase the proportion of animal sex (protein), such as silkworm pupa. Increase the amount of investment to promote fast growth.

In winter, the weather is relatively cold, when the temperature drops to 0, the koi carp should be transferred to the indoor fish pond in time for wintering, the indoor water temperature should be kept at 2 10, pay attention to the focus is on heat preservation, appropriate bait, fat protection and disease prevention, from November to March of the following year for the koi wintering period.

The selection of koi fish should be observed from the following aspects one by one, and it basically meets the requirements, even if it is a good koi fish.

1.Observe the degree of health: no matter what kind of fish you buy, you must choose the kind of fish that swims flexibly, eats actively, has a well-proportioned and strong body, has wide shoulders and a thick mouth, and has a strong tail peduncle.

2.The body color of the koi: The body color of the koi fish is only one point, that is, it is thick and bright.

The white should be pure and warm cotton, the crimson should be bright as blood, and the ink should be thick and not scattered. For example, the red matter of koi is pink, without the assistance of color-enhancing feed, natural color, such koi is a high-quality breed, if you eat the color-enhancing feed and color of the koi, once you stop feeding the color-enhancing feed, the color is very obvious. To observe whether a koi fish has excellent genes, body color is the most direct manifestation.

3.Pattern: Looking at the pattern of the koi, different varieties have a clear attention, for example, the crimson color is not the nose, not lower than the eye; Taisho's ink is not on the top, and Showa must have face cutting and so on.

When buying 3-10 cm small koi, their body color is not obvious, and some will even bleed, so when we buy, do not buy small fry with blurred colors, even if they grow up, they will not have good quality, do not listen to the recommendations of bad vendors, and believe in their own vision.

According to a fixed scoring scale, the score of a koi fish can be divided as follows: 50 points for posture, 30 points for body color, and 20 points for suit color. The so-called posture includes its health, as well as its appearance, which is the best standard to prove the superiority and inferiority of genes, and the body color and pattern are the common embodiment of genes and later development, which can be seen whether the feeding is nutritionally balanced, whether the water quality is up to standard, whether the fish itself can maintain a good state and so on.
