Confucius said: food and color also! Koi lovers love koi not only because of its athletic physique and masculine swimming, but also because of the gorgeous colors on the back of koi. Koi lovers all want their koi fish to be colorful and mellow. Many fish friends have found that their love carp has become platinum after a period of time, and the color has faded badly. Some even the use of color-enhanced feed is not obvious. What is the reason for this? Here simply introduce the secret of brocade carp under grace! The principle of koi color enhancement: The reason why the color of koi is bright is because of the pigment cells in its body. There are four kinds of pigment cells in koi carp, which are melanocytes, yellow pigment cells, orange pigment cells and glorious pigment cells. Chromoyang feed only has a certain effect on yellow pigment cells and orange pigment cells, that is, it only increases red upenings. And what helps both types of cells is shrimp and crab feed. But the color young feed is not the more shrimp and crabs added, the better for koi fish. Especially when the variability of homemade feed increases, it should be used with care to avoid the deterioration of the texture of koi. There have been studies that the koi feed can only contain 3 to 5 mg of red plain pigment per 100 kri. Yellow pigments are generally found in algae and vegetables, but generally more than 20% will cause a burden on the internal organs, causing irreversible problems to the white matter of the koi in the future. It means that adding too much cyanobacteria or chromatin can actually damage the internal organs and affect the texture and. Therefore, although completely homemade natural koi feed is the best and safest way to raise color, it is still necessary to be very careful and not to blindly pursue the raising color ingredients. Environmental factors NO.1, the concentration of inhibiting nitric acid should be red, and the PH should be increased to 7.2~7.4. In the feeding season, the concentration of nitric acid will rise, the PH will decrease, at this time we must pay attention to check the filter tank, clean the sedimentation tank, release the bottom water at least 1 times a day, 2 to 3 times better, so that the dirt and ammonia will not all dissolve into the circulating water, how much can inhibit the concentration of nitric acid. It is also necessary to increase the additional amount of new water, in addition, at least once a month to regenerate zeolite, inhibit the concentration of nitric acid. In short, it is important to try to suppress the concentration of nitric acid. When nitrate concentration is high, the red color will fade, and when nitrite concentration rises, the whole upturn (red) will disappear. In the selection of young fish, you will find that there is no whole white fish after the first selection, but the second selection is found a whole white fish, because there is a high nitrite in the feeding water. At this time, you should check whether the filtration system and filtration materials are normal, whether they need to be cleaned, etc. NO.2, the sun irradiation and dissolved oxygen PH is normal, insufficient time, dissolved oxygen is not high, will also affect the color and. To make the fish grow fast, but also to maintain and Yang color, the daily amount should be more than 50%. If it can reach 70%, acid rain does not flow in, PH is maintained at 7.2~7.5, dissolved oxygen in the hottest summer is 7.5~7.8g/m³, spring is 11g/m³, autumn is 10g/m³, so it is not feeding the color feed, the crimson will also turn red. Why the long time, high dissolved oxygen, the upenium will turn red? This is because oxygen causes the upensin to condense in the epidermis, thickening the red color of the surface. In addition, the closer the dissolved oxygen is to the saturation point, the more nitrous acid will not be produced, and the color will be more red. NO.3, the color of solar water and disposal methods When the color of water appears white, first test ammonia, nitrous acid and dissolved oxygen. If ammonia is high, quickly increase the amount of new water, strengthen pumping or spraying. If the high level of nitrite and dissolved oxygen are reduced, the filter tank must be cleaned without reducing a large amount of pool water. When the color of the water is yellow, the concentration of nitrate may be higher than 30mg/kg, and zeolite must be immediately regenerated. When the color of the water is brown, the nitrate is more than 80mg/kg, and the nitrite is more than 5mg/kg. At this time, the fish will definitely suffer from gill disease and the goatsin will disappear no matter how much the water temperature is. At this time, increase the injection of new water, quickly dilute the pool water, and add zeolite to the filter tank to treat the pool water. When the color of the water appears green, the dissolved oxygen changes greatly during the day and night, and the fish are in danger of jumping out. When you get up in the morning, you find that fish are injured, often because the dissolved oxygen at night is reduced, and the fish feel uncomfortable jumping, so be careful of the night and day dissolved oxygen caused by the effect of algae oxygen and carbon dioxide. The water in the pool turns green, sometimes because the treatment pool is dirty and the dissolved oxygen is insufficient. Or because the speed of treatment is too fast (water flow), the dirt has been circulating without treatment. At this time, increasing the water lift of the pump is also one of the ways to solve the problem. NO.4, white ground and ink quality improvement method if the nitrate can be kept below 5mg/kg, white ground will become very white and have. This is because the acid concentration in the water increases, the metabolism slows down, and the toxins in the body cannot be removed, and the white ground will become not white. When the new water amount is increased, zeolite regeneration, nitric acid reduction, dissolved oxygen rise, white land will be significantly improved. To maintain the water quality of the white land without polluting it, do not let the feces turn in the water, but discharge the bottom water from the bottom of the pool, and the pool water slowly turns to make the precipitation of organic matter produce an effect. The more dissolved oxygen, the lower the concentration of nitric acid, the better the ink quality. If the amount of additional water can be increased or decreased, and the silicon that can be slowly dissolved, then the ink will be black and bright. New cement ponds or ponds injected with a lot of groundwater to raise koi carp, the ink quality is better, because the silicon contained in the soil or cement helps the formation of ink. The relationship between ink quality and water temperature is not the main, mainly related to PH and dissolved oxygen. The ink quality of Dazheng three colors is easy to come out when the water temperature is 8~27 ° C, especially between 17~26 ° C. The ink quality of Showa three colors will come out when the water temperature is 13~20℃, and it is most obvious at 15~17℃. You can turn the temperature to make the ink more beautiful, but the water quality must meet the conditions. The age factor says that women have changed. Similarly, age also plays a decisive role in the color of koi carp. Koi is a poikilothermic vertebrate, and the general color change is affected by nerve action, and hormones play an important role. So the most intense period of color change in koi is when the age is two to eight years old is the most stable and most beautiful time. However, koi will be affected by feeding, health, spawning, aging, and so on. From this point of view, in fact, the color of koi carp is the same as that of birth, old age, illness and death, and indeed cannot be forced. There are other factors that affect color enhancement. It is said that the stress of koi carp, the ability to adapt to the environment, etc., which is less known. Stress will cause increased melanin in koi, which may cause the problem of red and white black spots, which is related to the secretion of the pituitary gland. Similar experiments have been done in Japan and found that stress does affect pigment cells. Low dissolved oxygen in the water, deteriorating water quality, bacterial infections, external shock, etc., can be a source of stress. From this point of view, providing a good living environment for koi is one of the key points for koi to ensure color quality. Here is a friendly reminder that many fish friends spend a lot of money to buy imported fish, and find that the state is not as good as before, and the color is not so bright and beautiful. In fact, the reason is that many imported fish have been fed Seyang since childhood. This is just like the fish you bought grew up drinking this milk, and came to you to drink porridge. It must be different! So the most suitable for their own is the best!
