What problems should be paid attention to in raising koi fish at home?

Koi habitsKoi picking: The best choice for koi fish should be bright colors, clear markings, and neat edges. The red quality of the koi is peach-colored, and the koi with good red quality is beautiful and thick.

And if you use the color to promote the red of the feed, it is more turbid and unnatural. In addition, it is easier to identify koi that are more than 15 cm tall, and the appearance of koi that are too small will change as they grow.

The body shape of the koi should be one with a straight back, a balanced left and right body, and a steady and upright swimming posture. The shape of the cheeks and the position of the mouth are upright, the ends are full and not concave, the fins should be symmetrical, complete, flexible, and strong.

Koi rearing: The tap water is stored in a bucket to dry for 2 days to remove chlorine, the drying process will also increase the oxygen content in the water, the body temperature of the koi will change with the change of water temperature, if the water temperature changes abruptly, it will cause discomfort to the koi, the best water temperature should be controlled at 23 28. Hard water is more conducive to the growth of koi carp, well water is hard water, and tap water is soft water.

Sudden switching from hard to soft water can also cause discomfort in koi fish, which is why the water is mixed with water.

It is also fed 2-3 times a day, and it is best to feed the koi for seven or eight points. If it is the breeding season, the amount of koi bait can be reduced by half or one-third, and the amount of koi fish can be reduced by two-thirds if it is weak and sick.

Because koi fish are larger in size and have a long lifespan, if you are a real koi enthusiast or feng shui fish enthusiast, it is recommended to customize the fish tank and not use the kind of small aquarium sold in the supermarket.

How to clean the koi fish tank, if you buy the kind of fully automatic fish tank, with a cleaning system, you can change the filter cotton or clean it once every half a month.

Koi fish tank maintains water quality, and koi fish do not have high requirements for water quality. 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. Another issue to be aware of is not to let the oil contaminate the bathtub, otherwise it is easy to cause hypoxic suffocation.

Don't plant aquatic plants, those aquatic plants are very expensive now, and if you raise koi, the aquatic plants will soon be eaten, and the gains outweigh the losses.

Benefits of Fish Farming::

Raising fish and raising gods, "The Yellow Emperor's Neijing" says: "Tranquility is hidden, and restlessness is extinction." Fish farming can calm people's hearts, so that the owner can concentrate and meditate through fish farming, less restless, and the movement of fish farming is a single-minded and unmixed movement of raising the spirit.

Fish farming requires patience and carefulness. Patience is constant, and care is subtle. Lao Tzu said: "The big things in the world must be done in detail", and Du Fu has a poem that says: "The beginning knows that Hao is placed in the subtlety". Therefore, changing the water and feeding every day is a kind of practice.

Fish farming, fish farming, usual observation is the most important. Sun Guoting said in the "Book Pedigree": "Those who observe it are still fine, and those who imitate it are expensive." When raising ornamental fish, we pay special attention to the observation ability of the eyes, including the state of the fish and the changes in water quality.

Fish farming is the process of learning to appreciate beauty, discover beauty, and create beauty. For example, the landscaping of the fish tank and the matching of fish polyculture, etc., in fact, we are creating a dream world for the fish, and also looking for a spiritual space for ourselves to relax and decompress.

How should koi fish be raised, and pay attention to preparing to raise koi fish.

How should koi fish be raised, and pay attention to preparing to raise koi fish.

1. Changes in water temperature.

Koi are afraid of drastic changes in temperature. When changing the water, be careful not to "shower the head water" of the fish, and inject it slowly against the tank wall, and the temperature difference should not exceed 2 to 3 degrees Celsius in a short period of time.

2. Maintain good water quality.

Koi fish can be eaten and pulled, and there must be a strong filter!

3. Food diversity.

Koi fish are omnivores, and can be fed with minced vegetables, garlic, and bread worms 1-2 times a month.

Fourth, bare tank feeding.

Koi swim vigorously, and too many decorations and stones and other objects in the tank can easily cause koi scratches and cause lesions (such as perforations, prints, etc.).

Fifth, use less medicine and provide more oxygen.

Koi are aerobic, and it is best to use an air pump to supply oxygen 24 hours a day. If the disease occurs, try to use as little medication as possible and increase the amount of oxygen.

Nothing else is particularly special, just pay attention to the feeding density.

Koi fish (Cyprinus carpio haematopterus) belong to the family Cyprinidae biologically, and there are more than 3,700 species of carp in 210 genera worldwide. It is a kind of high-end ornamental fish that is popular in the world today, and has the reputation of "living gem in water" and "art that can swim".

1. Koi stocking: When you buy back the carp from the farm or aquarium (store), you must first rinse the plastic bag with water and clean it with the whole bag of fish into the pool, and after about 15 or 20 minutes, the pool water will be flushed into the bag (so that the water temperature inside and outside the bag is balanced, and the water in the original bag should be discarded under normal circumstances), slowly put the fish into the prepared basin, soak it in 3%-5% salt water and then enter it. It is best not to feed the fish that has just been bought for 2-3 days.

2. Bait: Koi fish are omnivorous fish, and animal or plant bait can be fed. However, in order for koi to be colorful, in addition to water quality factors, it is more important to feed high-nutrient special koi fish to enhance the color.

The principle is to feed a small amount and many times, and too much will cause diseases such as food accumulation and constipation. Feeding fish adheres to the principle of "four determinations", that is, timing, positioning, quantitative, and qualitative.

3. Seasonal management: In spring and summer, the feeding should be gradually increased from a small amount, and plant feed should be fed as much as possible. Autumn is the most suitable season for koi to grow, and you can feed more feed with higher animal protein.

In winter, when the temperature is lower than 10, feeding should be stopped, the water temperature should be kept above 4, and the management work such as changing water, adding water, and removing dirt should be reduced to a minimum.

The specific amount of bait: to give eighty percent full, to the extent that it can be eaten in 30 minutes. The bait is generally given at 10 a.m.

Around 4 p.m., bait is given, and no bait is given in the evening.

4. Water source: river and lake water, well water, spring water, tap water. The water is filtered and can be used

Well water and spring water need to be exposed to the sun for 12-36 hours, and the water temperature is suitable before fish can be raised. Let stand for 2-3 days before the chlorine gas volatilizes before raising fish.

5. Water temperature: Koi fish live in the water temperature range of 4 -30, the most suitable for living in temperature 21-27, and the general water temperature changes 3

6. Dissolved oxygen: Koi fish live in water and rely on gills to absorb oxygen dissolved in water, and whether the amount of dissolved oxygen is sufficient is the key to raising koi. Therefore, it is necessary to inject oxygen into the water, use an air pump to pump the air to dissolve the oxygen in the water or replace the fresh water frequently, and remove the residual bait, feces and other organic matter in time.

7. Hardness: Koi fish like to live in a slightly alkaline and low hardness water environment. Generally speaking, carp can be raised in both soft and hard water, so avoid moving koi fish from soft water to hard water abruptly to avoid allergies.

8. pH (pH value): The pH value of water is 7 to indicate neutral, below 7 is acidic, and above 7 is alkaline.

9. Nitrite, ammonia nitrogen and other harmful substances; The excrement of koi fish is contained in water, and harmful substances such as nitrite and ammonia nitrogen are produced through various ways. When the concentration of harmful substances is too high, it often causes the nameless death of koi. Raising Jinlu must pay attention to the management of water quality, a good filtration system to breed a large number of beneficial bacteria is conducive to reducing ammonia nitrogen.

Be careful not to feed too much, novices should remember this. In addition, it proves that there is a lack of oxygen at the beginning, and it is enough to change the water or oxygen.

Carp cannot be raised with real grass. Since I am also a novice in fish farming, I have only heard that I should not put peppercorns on koi fish before. The fish will eat it.

I would like to experiment with whether carp eats nori or not. So I put a few real grasses in the fish tank, and it ate grass with bare hands after less than three days, as you can prove by looking at the picture below. What should I pay attention to when raising koi fish?

Second, don't raise the density of carp too much, carp This fish eats too much, eats long, eats fast, buys more than ten centimeters when you buy it, and grows taller in a few days, and you have to see that the dough has become bigger. Oxygen to watch the fish is not enough. Especially when it rains, it is low.

The fish swim to the surface to breathe. Therefore, carp farming should never be too dense. What should I pay attention to when raising koi fish?

Thirdly, carp farming will use as wide a tank as possible.

My fish tank is 80 cm high and 30 cm wide. The carp looks down at the fish, so the fish are still stuffy in my tank and can't swim, and the carp is not so beautiful when I look at it from the side. What do I need to pay attention to when raising koi fish?

Fourth, don't feed too much koi. In the summer, oxygen is already low, so the oxygen consumption of nitrifying bacteria is relatively large. If you eat some more fish, you won't be able to eat fish, and it is easy to damage the ecosystem, and watch the water quality deteriorate little by little, and watch the fish tank turn white.

The whitening of the fish tank water is the mass death of nitrifying bacteria, and the small white dots are the corpses of nitrifying bacteria. Therefore, if you raise carp, don't feed too much.

In the case of carp, indicators such as ammonia nitrogen, nitrite, and pH in the water must be constantly observed. The closer the first two values are to 0, the better. The pH value is best between.

Below or above it should be taken seriously, which can usually be adjusted by changing the water. Temperature: The survival temperature of carp is between degrees, 22 to 28 degrees is the best water temperature for carp to grow, when the water temperature is lower than 31 degrees, the growth rate of the fish decreases, and when the water temperature is lower than 10 degrees, it basically does not grow.

Therefore, in the process of breeding, it is necessary to control the water temperature as much as possible within the suitable temperature for the growth of the fish, and pay attention to temperature fluctuations. When changing the water, it is best to control the temperature difference of the water within 2 degrees.

Under normal circumstances, it would be better for us to eat less. When the water temperature is above 20 degrees, 3 or 4 times a day, and when the water temperature is below 20 degrees, 2 or 3 times a day is fine. When it is below 10 degrees, it is fed once at noon when the temperature is high, and it is not necessary to feed it on low temperature and rainy days.

It is best to feed and eat between 20 and 30 minutes. Too long or too short is not good for the growth of the fish. In addition, for the best fish, it is necessary to choose the appropriate feed when feeding the fish, if the fish is fed inferior feed, it will seriously affect the quality of the fish.

Fish farming must focus on the prevention of language diseases, and we must do a good job in the prevention of language diseases, and deal with problems in a timely manner. Under normal circumstances, if there is no problem with the water quality, the bait can be mixed regularly in the feed fed and fed to the fish to improve the resistance of the fish to disease.

When breeding koi, we must pay attention to the water environment, clean it regularly and prepare for sterilization, and maintain a good water temperature to make it grow better.

The first point should be noted that the process of its breeding should be carried out in a timely manner, feeding some food, the second point should be paid attention to spraying some drugs when sick, so that it can be, and the third point should pay attention to the temperature, so as to breed well.

1. Don't overfeed, usually only once a day, remember not more than two feedings a day. Feeding koi fish too much will only kill them.

2. Choose the koi fish tank correctly, pay attention to the smaller the koi fish tank, the more difficult it is to control the water quality, the larger the water capacity of the koi fish tank, the lower the difficulty of controlling the waste concentration.
