What is the best color of koi and the selection of koi?

The main purpose of screening brocade carp is to eliminate the bad fish and select the good one with ornamental value. So how to screen the superior brocade carp with ornamental value? The screening of koi is nothing more than looking at the size and size of koi, and to select superior koi, koi must carry out a layer of observation, discussion and appreciation of koi experts to eliminate unqualified koi.

The screening of brocade carp is not only the screening of the evaluation meeting, but also the screening of parent fish and fry, and the screening points of different species are also different.

First of all, the screening of the evaluation meeting is actually how to appreciate the koi. The screening of the koi can be said to be the most luxurious, luxurious, and most exciting screening of the koi. If your koi get a very high evaluation at the screening meeting, there will be a lot of koi players to buy from you, and the price will definitely surprise you. According to the survey, koi players bid millions to buy a koi. So where is the screening point for koi in the evaluation meeting? There are six points:

1. Eyes: whether the distance between the two eyes is wide enough, if the distance between the two eyes is wide, this koi is relatively large.

2. Lips: whether the lips are thick or not, it is difficult for koi with thin lips to develop large fish.

3. Pectoral fin: the pectoral fin is too small, too sharp, and the triangle is not good; when the koi swims, the pectoral fin moves forward too much and looks very laborious, indicating that the fish is not very healthy; the body from the pectoral fin to the caudal stalk should grow smoothly without sudden protuberance or depression.

4. Head: whether the head is long enough, whether the cheeks of the head are plump, whether the top of the head is plump, and the koi whose top is flat is not ideal.

5. Tail: the caudal handle should be strong, the caudal fin should not be too long, and the fork concave of the caudal fin should not be too deep; the highest point of altimetry should be in front of the dorsal fin, if it is in the middle of the dorsal fin, it is not good.

6. Beard: the beard should not be too short, but because the brocade carp will hit the wall or break the beard or damage caused by parasite infection when frightened, no matter how long it is, it will be very short, so this is for reference only.

Secondly, when it comes to the screening of brocade carp parent fish, this is also very important, because it is related to the breeding fry of koi. If there is no good fry, no matter how much evaluation there is, there will be no superior koi. In order to reproduce a better koi, the parent fish must have a healthy physique, no body defects, strong color, bright color and luster; the markings should be clear and balanced between left and right, and the shape should be coordinated. The ratio of body height and length is 1: (2.6: 3), beautiful swimming posture, obvious and clear species characteristics, and so on. The body type of parent fish is flat up and down, flat and oval in profile, and spindle-shaped as a whole. The age of male and female of brocade carp is also different. Although the age of sexual maturity of brocade carp is earlier in nature, the age requirement is also necessary in order to breed better quality brocade carp. The best choice for male fish is between 3 and 5 years old, while the later age of female brocade carp is between 4 and 10 years old, while the physique of such parent fish is relatively strong, the gonads are full, the sperm and eggs are more active, and the fertilization rate and hatching rate are very high. It is very ideal to be a parent fish; if the age of brocade carp parent fish is too old or too young, the fertilization rate and hatching rate will be greatly reduced.

The screening of brocade carp fry is one of the preparation conditions for raising brocade carp: in brocade carp, the most important thing is body shape, so that we can choose a good body shape and focus on which parts; the body type selection of brocade carp fry is mostly the same as the appreciation standard of the evaluation meeting. But also to see its swimming posture, put the fry in the basin to see if he swims very hard, painstaking to show that it is not very strong, the body from the pectoral fin to the caudal stalk this section of body shape must be very smooth, although the fry period color is not very good-looking, but to ensure that there are no miscellaneous colors, color spots evenly distributed, not immediately to the eyes, cheeks, nose.

Variety selection of red and white: red and white should be coordinated, there should be a sense of integrity, regardless of white matter or red matter can not be turbid. Be uniform and fine. Red should be thick, with a balanced, uniform and symmetrical flavor. Red basically has two tones: one is dark red based on purple, which is low but not easy to fade; the other is bright red based on orange, which gives people a bright and soft excitement and a higher style.

Dazheng tricolor is a koi with uniform and coordinated red and black markings on a white background. But there must be no black markings on the head. The appreciation of Dazheng tricolor red is the same as that of "red and white". It is necessary to balance left and right and stabilize the center of gravity. Black markings are required to be as uniform, dense and glossy as red matter. Generally speaking, the ink color of Dazheng tricolor is unstable, and the ink color will slowly show and stabilize only when the koi grows to the age of 2-5 years old.

Zhaohe tricolor appreciation: Zhaohe trichromatic crimson and red and white crimson appreciation require balance, coordination and symmetry, while ink is the focus of Zhaohe tricolor appreciation, the ink spots on the head should show lightning patterns, it is best to split the head in the shape of "eight" or "human", and the top of the head (nose) should be black. The dark spots on the body that roll from the abdomen to the back are more beautiful than those that extend from the back to the abdomen. The black spot of the pectoral fin must be round, and there should be no striped ink spots, which should be pitch black or blue-black and shiny, so that they can be more bold and unrestrained when matched with bright red. There must be no purple-black or matte pot smoke. The ink color of Zhaohe tricolor is as unstable as that of Taisho tricolor.
