Why do wild carp turn yellow and what is going on with the yellowing of carp

This is due to the wild environment, water quality, feed are related. This characteristic is also what distinguishes wild carp from farmed carp.

There are 4 main differences between wild carp and farmed carp:

Body type: Wild carp react quickly and are elongated; Farmed carp swim slowly and are fatter.

Exterior color: The back of farmed carp is black, and the back of wild carp is golden yellow with fins.

It is also golden yellow.

Meat quality: Wild carp feels very solid and hard when caught in the hand; If you catch the farmed carp by hand, there will be a concave handprint on the place where you have caught it, and it will be soft.

Whiskers: Wild carp have long and stout whiskers; The whiskers of farmed carp are thin and small, hanging down on both sides.

That's not yellow. It's golden. That color can only be grown in water with a good environment.

There are many reasons for the yellowing of fish, some fish are born with discoloration, and after a long time, they will have a protective color, so don't worry too much. Others are because the water quality is not good, and the water body is wide and the tung is poor, which leads to the change of the body color of the wheel spike, as long as you pay attention to the water change, it can also be slowly improved. There is also a possibility that you are sick, in this case, do not use medicine first, change the water to heat up the salt and try the socks to see, if there is an improvement, it will be fine, and then take a medicated bath if the situation is serious.

Due to the wild environment, it is related to water quality and feed. This characteristic is also what distinguishes wild carp from farmed carp.

There are 4 main differences between wild carp and farmed carp:

Body type: Wild carp react quickly and are elongated; Farmed carp swim slowly and are fatter. Appearance color: the back of farmed carp is black with tan oak, the back of wild carp is golden yellow, and the fins are also golden yellow; Meatiness:

The wild carp feels very solid and hard when caught in the hand; Grasp the farmed carp by hand, and the place where the hand has caught will leave a concave handprint, which is soft; Whiskers: Wild carp have long and stout whiskers; The whiskers of farmed carp are thin and small, hanging down like they are trapped on both sides.

Carp is a common freshwater fish with a very keen visual system. According to research, the visual system of carp is very sensitive to yellow, so when carp see yellow objects, they feel excited and excited.

This is because the yellow wavelength of light is one of the strongest wavelengths that can be perceived by the retina of carp, and yellow objects are more visible in the water because they are more bright. In addition, yellow is also the color of many carp in liquid jujubes, such as insects, aquatic plants, etc., so they often regard yellow as the representative color of food.

In summary, the preference and excitatory response of carp to yellow are determined by the characteristics of its visual system and the feeding habits of the species.

Hello dear, carp eat earthworms, red worms, carrots, green leaves, shrimp and other brightly colored ingredients, feed it once a day to make it yellow. You can also increase the light: fix the fish tank in a well-lit place for two to three days a week, and ensure that the light time is about five hours per day.

Improve the pH value: Adjust the pH value of the water used to raise koi fish. Adjust the background color:

If you want the koi to not fade after adding color, it is best to change the background of the fish tank to a dark color. Hope it helps you <>

Do you have any other questions that I would like to answer for you, dear? <>

Summary. Hello, want to add color to the carp in addition to the light, background and water quality, more important is to feed high nutrition of the special koi color artificial feed, there are flakes or granules, this color or called the color of the feed is to maintain or increase the color of the koi fish and specially made, the main ingredient is to use salmon, trout muscle pigment (flaxanthin), after the koi eat, the red part will be significantly enhanced, you can go to the market to see, generally there are <> for sale

What do carp eat to make it yellow?

Hello, want to add color to the carp in addition to the light, background and water quality, more important is to feed the highly nutritious special koi color artificial feed, there are flakes or Chang cavity granules, this color or called the color of the feed is to maintain or increase the color of the koi fish and specially made, its main ingredient is to use salmon, trout muscle pigment (xanthin), koi after eating, the wheel of the red part of the wax will be significantly enhanced, you can go to the market to see, generally there are <> for sale

In fact, it is very simple, if you want to add color, you must feed color-enhancing feed, and you can usually feed Huai scattered bloodworms, only live bait feed has an effect. Koi fish are omnivorous fish and can be fed with animal or plant-based bait, such as daphnia, earthworms, small shrimp, corn lead powder, cracker chips, instant noodles, vegetables, and even rice balls. <>

The reason why carp has color is mainly because it contains pigments in its **. Carp**Zhongyou Bijing mainly contains three pigments: melanin, yellow pigment and red pigment, which can be combined to create different colors, such as golden yellow, silver gray, red, black, etc. The production and distribution of these pigments are related to the physiology and environment of the carp, and in general, the ** color of the carp will change with the change of age, sex, season, digital environment and other factors.

In addition, the color of carp is also related to its nutrition and farming methods. For example, adding some natural pigments or chemically synthetic pigments to the feed can enhance the ** color of the carp, making it more vivid and beautiful. At the same time, the water quality, water temperature, and light of the breeding environment will also have an impact on the color of the carp.

In short, the color of the carp is composed of the pigments in it, which is affected by a variety of physiological and environmental factors, and is a natural and changeable color.

Carp have color because they contain pigments. The pigment in the carp is ingested through the first state of the cavity. The main food ingested by carp is aquatic plants, plankton and small benthic animals, which are rich in pigments, especially carotenoids and algae pigments.

These pigments are absorbed by the adipose tissue in the carp and converted into celery pigments, giving the carp a different color on its body. Different species of carp have different colors and markings on their bodies, which is due to the differences in the ability of different species of carp to absorb and transform pigments during the evolutionary process.
