Koi has been regarded as auspicious by the Chinese since ancient times. It is often raised in the pond of the mansion’s deep courtyard. With the spread of koi breeding and koi culture in recent years, koi has become more and more popular as a feng shui fish. Koi is of great ornamental value, rich in patterns and beautiful colors, put in the pond, it is pleasing to the eye and eye-catching.
As more and more people raise koi, the problems encountered are endless. Why does the color of koi become lighter? What effect does water in different environments have on the growth of koi?
We know, scarlet , white, strong 25strong _span strong are the three core colors of strong strong 25strong . Only when the three colors cooperate with each other can there be a koi that really makes people feel heartbeat at a glance. Today I’m going to talk about how to improve the color and freshness of koi by managing the water quality, feeding and lighting of the koi.
1. How to improve scarlet, white, and ink colors:
1. How to make the “white ground” bright
p0 A, as much as possible to eliminate salt in the water span12spanB, enhance the biological filtering effect,Keep the rearing water pure, if possible, drain the bottom water of the fish pond every day, add oxygen-explosive fresh water
C, strengthen the oxygen melting of the rearing water, increase the air circulation of the breeding environment
D, keep The softness of the feeding water
E, completely remove the iron in the water
F, increase the amount of feed containing calcium

A. Keep the pH of the water between 7.0 and 7.2. You can place coral sand or oyster shell
B in the filter tank or in the water circuit. Feed natural carotene-containing feed
3. How to make dark spots deeper
A, keep a relatively low water temperature and a pH value slightly lower than 7.2span_span_span_span_span
B, reduce the chance of Koi carp directly exposed to the sun
C, reduce the feeding of fat-containing feed, this type of feed will reduce the excretion of Koi carp
D, in a certain period of time The hardness of the feeding water can be increased by adding water of appropriate hardness ,Afterwards, the original hardness can be used to strengthen the ink quality of the black spot carp;
two span_span_strong2ppan0pstrongp The color of the carp is mainly determined by the pedigree, feed, and water. If the pedigree and feed are good, and then the water is treated well, the color of the koi can be perfectly expressed.
1. The relationship between koi's body color and water temperature
The color will be affected by the water temperature and change, for example, in summer when the water temperature is higher, the body surface color looks lighter, and vice versa , When the water temperature is low, the color will be more intense. Sometimes we may find that the color of the koi is lightened after being brought home for a period of time. This is because most of the koi franchise stores use well water to raise the koi, and the temperature of the well water is lower. , And use tap water to raise after buying home, the temperature is relatively high, so the color becomes lighter.
2. The water quality factor that makes the koi white ground more vivid
eliminates the ammonia in the water as much as possible. If the ammonia content is high, it will cause the fish body to renew Toxins are discharged slowly, and the white ground will become worse. Enhance the filtering effect and keep the feeding water pure, if possible. Suction the feces at the bottom of the pool in time every day and replenish dechlorinated fresh water. Increase the dissolved oxygen in the water,The increase in dissolved oxygen helps to reduce the ammonia content.
3. Water quality factors that make koi red spots brighter
keep the pH of the water between 7.0 and 7.2. Coral sand or oyster shells can be placed in the filter tank to improve the water body的PH. Appropriate light and high dissolved oxygen are easy to cause red matter to condense on the epidermis. If the dissolved oxygen is high, the ammonia concentration will generally be low, and the pH will not decrease. If the dissolved oxygen is low, the ammonia concentration will increase, and the pH will decrease. Therefore, it is necessary to take measures such as sewage and water exchange to control the concentration of dissolved oxygen and ammonia.
4. Water quality factors that make koi ink spots darker
Keep the water temperature relatively low. The hardness of the aquaculture water can be increased appropriately, and then return to the original hardness after a period of time, which can strengthen the precipitation of the color of the koi ink.
Of course, water quality factors are one of the reasons that affect the body color of the koi. Other factors include the age, stocking density, feed and ancestry of the koi. I suggest that all aquarists, don’t worry if you find that the color of the koi is fading, and find out the cause, which is the solution to avoid the color of the koi again.
Finally, let’s talk about why can’t we feed the koi before moving?
Koi must stop eating before moving. Why is this?
Answer: Stopping feeding can also be called "hanging water".Koi with poor hanging water are particularly sensitive to the movement of . If it is transported to a distant place without stopping, the skin of the koi will have symptoms such as hyperemia and protruding eyeballs... But these symptoms are not bad, and there are many deaths, so it is absolutely necessary to stop feeding before moving.
So, why do you have to stop feeding before moving? If there is food in the abdomen and put it in a plastic bag, the koi itself needs to consume a lot of oxygen in order to digest the food. Not only that, but the carbon dioxide will also increase. In addition, the feces and urine produced by Koi will deteriorate the water quality. That is, the probability of hypoxia, gas poisoning, and ammonia poisoning is very high.
Also, if the koi shakes around in a full belly state, you may get motion sickness.
also causes pressure on the koi due to movement, which makes the function of the intestines worse, and sometimes even does not work. In this way, there will be residues in the intestines decayed, the breeding bacteria will spread throughout the body through the blood vessels, or the gas will stay in the body and press the internal organs and other dangerous situations. The various situations and their inferences are explained above. Please stop eating 5-7 days before moving.
Note: Koi carp may also eat green algae in the pond after stopping feeding, so that it has not reached the real stop. The so-called cessation of food means to completely empty their intestines. Therefore, if there are green algae in the pool, find a way to use the preparatory basin.
