I am a novice how to raise koi well, how to raise koi fish as a novice

First, the environmental requirements of koi and goldfish are not strict on water temperature and water quality, the appropriate temperature range is 2 30, but can not resist the sudden change of water temperature, the temperature difference suddenly exceeds 2 3 koi will be uncomfortable, the optimal water temperature is 20 25; It requires sufficient oxygen and is suitable for living in a slightly alkaline and low-hardness water environment.

2. Feeding requirements Koi fish are omnivorous fish, which can be eaten by mollusks, higher aquatic plant fragments, benthic animals and even fine algae or synthetic pellet bait.

3. Fish species selection should be selected with healthy fish body, no injury, no descaling and other diseases, bright fish body, diverse colors and clear boundaries.

Fourth, the stocking density of the fish pond density can refer to the density table of the fish pond stocking koi; The density of the water cluster box is generally 60 cubic centimeters, 30 cubic centimeters, 15 cubic centimeters, and 6 koi fish with a body length of 15 centimeters and 20 centimeters; 90 cubic centimeters, 30 cubic centimeters, 50 cubic centimeters, can be stocked 8 tails; 110 cubic centimeters, 30 cubic centimeters, 50 cubic centimeters, 10 tails can be stocked.

Fifth, bait feeding.

Koi fish are omnivorous fish, and it is best to feed synthetic pellets, bait, bean cakes, vegetable cakes, bread crumbs, fish insects, clams, crab meat, turnips, duckweed, etc.

6. Four Seasons Management The management methods of koi fish vary with the change of seasonal temperature. In spring, the weather is warm and cold, the koi begin to recover from hibernation, and the feeding is transferred from indoor to outdoor, but special attention should be paid to the sudden cooling, and the film should be covered in time to keep the water temperature stable; The bait is mainly plant-based bait, and the amount of bait gradually increases from less to facilitate the digestion and absorption of koi. In summer, when the weather is hot and hot, it is necessary to cover with a plastic shading net to prevent direct sunlight, so that the sunlight illumination is reduced from 8000 12000 lux to 5500 5800 lux.

In autumn, the weather is less rainy and more sunny, and the water temperature drops significantly, which is the most suitable for the growth of koi carp, which can increase the proportion of animal sex (protein), such as silkworm pupa. Increase the amount of investment to promote fast growth. In winter, the weather is relatively cold, when the temperature drops to 0, the koi carp should be transferred to the indoor fish pond in time for wintering, the indoor water temperature should be kept at 2 10, pay attention to the focus is on heat preservation, appropriate bait, fat protection and disease prevention, from November to March of the following year for the koi wintering period.

It is best to raise it in a pool.

Raised in a tank, the filtration must be super powerful. Change the water frequently. Change 1 5 every 3 to 5 days.

for they ate and drank Lazar in abundance. Fish can also pee. So keep the water fresh.

Only frequent water changes. Otherwise, you will get sick with love.

Control the water, fish food can not be single, small fish, artificially bred insects, fruits...

Fill with water. Throw it down! Water is no problem. Fish is good!

Try not to raise it in a red container.

Novice koi fish are as follows:

1. Maintain water quality

Koi do not have high requirements for water quality, and there is a lot of excrement every day, so buy a filter (which runs 24 hours a day) and filter the water quality while delivering oxygen. Generally, the daily consumption of electricity is less than 1 kWh. The frequency of water changes is once a week, one-third to one-half of a water change at a time.

Do not change the water too much at one time, which will cause the instability of the ecosystem in the fish tank, and it is easy for the koi to be unadaptable.

Second, the cleaning of the fish tank:

If you buy the kind of fully automatic fish tank, it is equipped with a cleaning system, and you can change the filter once every half a month or clean it once. However, koi fish are not such complicated equipment, so the fish tank is easy to grow green moss, and the way to prevent green moss is to clean the fish tank frequently.

When cleaning the fish tank, take out all the fish, and keep half of the water so that you don't pour it out, and pour it back after cleaning the fish tank. If you don't have time to clean your fish tank often, you can put it in a cool place away from direct sunlight and put wallpaper on a sunny area.

3. Don't plant aquatic plants:

Now those aquatic plants are very expensive, and if you raise koi, the aquatic plants will be eaten quickly, and the gains outweigh the losses. And eating the leftover residues can easily pollute the water quality. My method is to raise aquatic plants in a separate pot and regularly add aquatic plants to the tank to replenish nutrients.

Fourth, the control of water temperature:

If the weather is particularly cold, pay attention to putting some nutritious fish feed to supplement calories. If the weather is particularly hot, feed less food, clean the fish tank more, and change the water more. When changing the water, pay attention to the water temperature, if you suddenly put the koi fish in cold water, it will be difficult for it to adapt, so put the water in the basin to cool for a while, so that the water temperature and temperature are about the same before pouring it into the bathtub.

5. Food: Koi fish are omnivores, crickets, earthworms and other insects can be eaten, and vegetarian foods such as bread crumbs and steamed buns are no problem. In short, it eats basically everything you eat. If you feed a lot, you should change the water frequently, and the more you feed, the worse the water quality will be.

How much feed is appropriate for a fish? The general standard is that after you feed the koi, the koi will eat quickly, and you will feed a little more. If the koi haven't eaten within 5 minutes, you've fed a lot.

Sixth, the irradiation of the light:

Koi do not need special lighting, but for sterilization, you can also buy those that have a sterilizing effect and leave them on for an hour or two at night. Of course, this is not to say that this lamp is ineffective (some hospitals also use this principle to sterilize), but I can't see it.

7. Pond and tank culture:

1. Pond culture. The main difficulty of pond cultivation is that not everyone has the space and reasonable conditions for pond farming.

2. Tank culture. The main difficulty of tank culture lies in the oxygen supply filtration, and the water change needs to be changed slowly, because the tank does not touch the ground like the pool and the amount of water is large, and the water change is easy to cause large changes in water temperature, resulting in the weakening of the koi fish's cold physique.

It is recommended to raise a bare tank, because the koi is an artistic painting, the aquatic plants will be eaten up by the koi, and other rockeries take up space, adding some alkaline coral stone or volcanic stone is not for decoration, but alkaline properties make the color of the koi better and the body is healthier.

Feeding: Novices should raise koi fish and avoid overfeeding. Live bait can be fed in combination with artificial feed, but it needs to be sterilized before feeding live bait.

Water quality: Koi fish like clean and clear old water, and it is best to install a circulating pump for them when novice breeding to reduce the number of water changes. Oxygen:

Koi fish have a high demand for oxygen, and breeders also need to install an oxygen pump in the tank. Fish tank: Koi fish are larger, and it is best for breeders to choose a large hard fish tank to raise.

1. Feeding: Koi don't know how to be hungry and full, as long as there is food, they will always eat, so novices must not feed too much food to avoid them being strangled to death or gastrointestinal diseases. Under normal circumstances, it is enough to feed 1-2 times a day, and the amount of each feeding can be eaten in 5-10 minutes.

Koi fish have a variety of food habits and can eat a wide variety of foods, and the more common fish feeds on the market can be fed to them.

2. Water quality: Koi fish like clean and refreshing old water, but they can eat and pull, which is very easy to damage water quality, so the breeder needs to install a circulating pump for them, which can slow down the deterioration of water quality and reduce the frequency of water change. After installing the circulating pump, it is enough to change the water 1-2 times a week.

3. Oxygen: Koi carp have a large demand for oxygen, and in the process of feeding, if it is found that the oxygen is insufficient, it is necessary to immediately oxygenate or change the water to ensure that the amount of dissolved oxygen in the water is sufficient.

4. Fish tank: Koi fish are larger in size when they become adults, so it is best for breeders to choose some fish tanks with high hardness to raise them.

To raise koi fish, the first thing to pay attention to is density, they grow faster and have a high demand for oxygen, if the density is high, it will make them hypoxic. The second is to pay attention to the environmental changes should not be too large, although the koi are adaptable, but they can not accept sudden changes in the environment, so the keeper usually needs to keep the surrounding environment stable. Finally, it is necessary to pay attention to the prevention of diseases, usually observe carefully, and once you get sick, immediately**.

The basic tutorial on koi raising for beginners is as follows:

If a novice wants to raise koi, he must first choose a suitable fish tank, because koi fish should be kept in a fish tank. At the beginning of the manuscript, the volume of the fish tank should be large, at least 80 cm or more.

In fact, before the fish tank is released, it is necessary to raise water for at least 10 days. In addition, the fish tank should be matched with a powerful filtration system, after all, the metabolism of koi fish is relatively vigorous.

Secondly, it is necessary to choose large koi, because if the novice is short of respecting the small koi, the small koi has poor resistance and is easy to die if it is not raised well. Whereas, the giant koi fish have stronger resistance and a lower mortality rate. Generally, novices raise koi fish between 25 cm and 40 cm, and observe the activity when selecting.

Since koi fish do not have a stomach, it is generally necessary to eat small and frequent meals when feeding koi. And when feeding koi, try to keep it to about 3 to 5 minutes. Koi fish can feed many things, but if you want to raise koi well, you must feed them for a special one.

Because the adaptability of koi fish to water quality is relatively strong, but when breeding koi, it is necessary to pay attention to changing the water. After all, koi fish are afraid of sudden changes in water temperature, and when the water temperature suddenly rises or drops to about 6 degrees, the koi may die. In addition, when breeding koi fish, it is also necessary to pay attention to the prevention of diseases.

1. First of all, it is important to control the density, and the number of koi fish should not be too much if the fish tank is relatively small. Then there is the water quality problem, it is very important to change the water regularly, and it can be changed every 3-7 days according to the specific situation. Then there is the problem of feeding, which can be fed once or twice a day, and the food needs to be richer.

It is also necessary to provide proper light every day. However, if the light is too strong in summer, it needs to be blackened.

2. Control density: To breed koi, we must first control the density. It is not correct to breed too many koi fish in small tanks, which can cause them to grow poorly.

Generally speaking, if the size is 60*30*15 cm, the number of koi that can be raised is about 6, and you can't raise too many.

3. Regular water change: It is also very important to breed koi fish and maintain suitable water quality. Therefore, it is necessary to change the water regularly and clean up 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 to 3-7 days, with more frequent water changes in summer and slightly longer intervals in winter. Each time you change the water barrier, 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.

4. Cooperate with Heng Lu Li feeding: Another important problem is feeding, which requires the use of normal feeding methods. First of all, you need to choose a good food, koi fish are omnivorous, so try not to use only one food, so it may be insufficient in nutrients.

You can combine plant and animal foods together, such as greens, earthworms, bloodworms, etc. It can be fed once or twice a day, once in the morning and once in the afternoon.

5. Proper light: When breeding koi, you also need to provide a certain amount of light every day. Especially if there are other plants in the tank, light needs to be provided for them to photosynthesize.

However, in the summer, considering that the balance line is relatively strong, they can be properly shaded.

6. Precautions: In winter, special treatment can be carried out to let the koi fish survive the winter, and they can be placed in a pool with a water temperature of 5-10 degrees. At this time, the number of feedings does not need to be too much, and it is enough to feed once every 3-5 days.

1. Fish tank requirements. If you use a glass fish tank to raise koi fish, the tank body should be relatively large, at least 80 cm or more. Before releasing water in the fish tank, it is necessary to raise water for at least 10 days.

In addition, the fish tank should be equipped with a powerful filtration system, it is recommended that 20% of the space is placed in the filter cotton and biochemical cotton for simple physical filtration, and 80% of the filter tank space is used to put the ceramic ring of the bacterial house, because the metabolism of koi fish is relatively large, so the ammonia nitrogen conversion in the water is more frequent, so more nitrifying bacteria are needed to deal with it.

2. Choose big fish. When raising koi fish, it is best to choose big fish, because small fish have poor resistance and are easy to die if they are not raised well; The big fish has strong resistance and a relatively large fault tolerance rate. Generally, novices raise koi, and it is best to start raising fish between 25 cm and 40 cm.

When we select, we can observe its activity, and we know that koi fish have the habit of jumping. The more robust the koi, the easier it is to jump from the tank, or swim fast and brightly colored, then such a fish is healthy and high-quality.

3. Feeding management. Because koi fish have no stomach, it is generally necessary to eat small and frequent meals when feeding koi, and it is recommended to keep it for about 3 to 5 minutes as much as possible when feeding koi. There are many things that koi fish can be fed, but if you want to raise koi well, you must feed special feed.

Koi feed is generally divided into five types: enrichment, breeding, color, germ and staple food. In addition, koi fish love to eat live bait, but live bait can cause damage to koi. Each feed has its own role and should be fed according to the temperature.

When the water temperature is lower than 20 degrees, it is recommended not to feed the body and color feed; When the water temperature is below 20 degrees, it is recommended to feed embryo feed.

4. Pay attention to water change. Koi carp have strong adaptability to water quality, but it is still necessary to pay attention to changing the water, in addition, koi are most afraid of sudden changes in water temperature, when the water temperature suddenly rises or drops by about 6 degrees, koi may die immediately. Therefore, when changing the water, be sure to control the temperature difference and do not exceed 3 degrees.

In addition, excessive levels of ammonia nitrogen and nitrite in the water can also cause koi poisoning, and in severe cases, it will lead to direct death of koi. If conditions permit, increase the biological filter tank and add more filter media to improve the filtration effect.

5. Disease prevention. Although koi fish are relatively easy to raise, they are also prone to illness. Generally, newly introduced koi fish should be quarantined first, and if conditions permit, it is best to isolate and observe for 1-2 weeks, and then put them into the main fish tank to raise them.

To prevent illness and mild illness**, sea salt is probably the best medicine. If the koi fish are always sick, the reason can be found from factors such as feeding density, filtration system performance, feeding amount, water quality control, and new fish quarantine.
