1. How to raise koi carp
1. When raising koi carp, you must first control the density. It is incorrect to raise too many koi in a small tank as this will cause them to grow poorly. Generally speaking, if the size of the fish tank is 60*30*15 cm, the number of koi that can be cultured is about 6, and you cannot raise too many.
2. When breeding koi, it is also very important to maintain suitable water quality. Therefore, it is necessary to change the water regularly and clean the impurities in the fish tank to provide a clean environment for the growth of koi. Specifically, the frequency of water changes can be controlled at 3-7 days. Water changes need to be more frequent in summer, and the intervals can be slightly longer in winter. Each time you change the water, you can replace one-third. In order to ensure that the water temperature does not change drastically, it is necessary to control the flow rate of the water and slowly inject new water.
3. Another important issue is feeding, which requires normal feeding methods. First of all, you must choose good food. Koi is omnivorous, so try not to only use one kind of food, which may cause insufficient nutrition. You can combine plant and animal foods, such as vegetables, earthworms, red worms, etc. Feeding can be done once or twice a day, once in the morning and once in the afternoon.
4. When raising koi, a certain amount of light needs to be provided every day. Especially if there are other plants in the fish tank, light needs to be provided to allow them to perform photosynthesis. However, in summer, considering that the light is relatively strong, they can be properly shaded.

In winter, special treatment can be carried out to allow koi to survive the winter by placing them in a pool with a water temperature of 5-10 degrees. At this time, the feeding frequency does not need to be too many, just once every 3-5 days.
3. Koi breeding technology and feeding methods
About Regarding this question, Koi is a common ornamental fish. Its breeding technology and feeding methods are as follows:
1. Water quality management: Koi has relatively high requirements for water quality. , it should be ensured that the water quality is clean, the transparency is high, the pH value is stable, the hardness is moderate, and the content of chemical substances such as ammonia nitrogen, nitrite and nitrate is controlled within an appropriate range.
2. Feeding: The feed for koi should be high-quality special feed. You can also add vegetables and fruits in appropriate amounts, but it is not recommended to add raw meat and Raw fish.
3. Temperature control: The suitable growth temperature of koi is between 18℃-28℃, and the water temperature should be controlled within the appropriate range.
4. Oxygen supply: Koi need sufficient oxygen supply, and the oxygen content in the water can be increased by increasing oxygen pumps or increasing water surface activity.
5. Disease prevention and control: Koi are prone to bacterial and parasitic diseases. Water quality and fish health should be checked regularly, and any abnormal conditions should be taken promptly. Corresponding treatment measures.
6. Breeding environment: Koi likes a breeding environment with sufficient light, luxuriant aquatic plants, and abundant shelter such as stones and branches. These elements can be set up in the aquarium. , improve the quality of life of koi.
4. Koi fish feeding methods and taboos
Choose fish that are strong, undamaged, and colorful. Breed fish species that have neat edges, clear markings, straight backs, good balance, strong body, steady swimming posture, symmetrical fins, and flexibility.
Determine the breeding quantity according to the size of the aquarium. Generally, an aquarium with a length, width and height of 60 cm, 30 cm and 15 cm can breed 15-20 About 6 centimeter-long koi can be cultured. A water tank with a length, width and height of 90 cm, 50 cm and 30 cm can breed 8 koi. A water tank with a length, width and height of 110 cm, 50 cm and 30 cm can breed 10 koi. Tail koi.
Koi fish often eat animal food bait and plant food food bait. Generally, koi fish like to eat animal food food bait. Common ones include fish, insects, and swords. Water fleas, paramecium, water earthworms, etc. Common plant food baits include turnips, aquatic plants, etc. When feeding fish, worms, pellet feed, small earthworms and other bait, do not feed too much. Generally, 80% full is enough.
Koi is required to be cultured in slightly alkaline water. The water temperature suitable for the growth of koi is 20-25℃. When breeding, be careful not to allow the water temperature to change suddenly, so It will affect the normal growth of koi.
1. When raising koi, if the water is not changed for a long time, the koi will suddenly die. If feeding is carried out as required, the water can be changed once a week. The amount of water changed is one-third of the total water. All the old water cannot be replaced at one time. When changing the water, be careful not to do it too fast, as long as it is done within 30 minutes.
2. Koi can only be fed once a day, and cannot exceed this number, because eating too much will cause a lot of excrement, which will affect the water. quality.
3. Novices who breed koi are recommended to use large fish tanks, which can easily control the water quality. If you choose a small fish tank, the water quality will be difficult to control
5. How to raise koi carp
In order for koi carp to grow healthily, it is necessary to Perform water changes regularly. If the stocking density is small, the water can generally be changed every one week. If the stocking density is high, the water can be changed every 3 to 5 days. One-fifth of the water in the tank needs to be replaced each time. The frequency of water changes is If it is too large, it will also affect the normal growth of the fish..
6. How to raise koi well
1. Water temperature: Don’t ignore the water temperature just because it is a cold-water fish and can adapt to a wide range of water temperatures. If you want your koi to grow big, the water temperature must be stable at 20-25°C. In winter and spring, when the temperature is low, you must turn on the heating rod in time to increase the temperature. As the temperature rises, its metabolism speeds up and it naturally grows faster.
2. Water quality: With good water quality, koi will not get sick and will grow faster and bigger. Therefore, you must provide it with a good water quality environment every day. It is best to change the water once every 3-5 days, and change one-third of the water each time, so as not to damage the stability of the system in the fish tank.
3. Food: As an omnivore, koi can eat many things. You can usually feed them whole grains, such as soy milk and soybean cakes. You can feed small fish, shrimps and lean meat. You can also feed apples, cabbage and other vegetables. In this way, koi fish are rich in nutrients and they can grow bigger.
