When are koi fish farmed and how to raise koi fish?

It can be farmed all year round.

Kindergarten children: As long as you don't freeze, you can do it anytime.

It can be farmed at any time.

Koi and goldfish have the same requirements for water temperature and water quality, and the suitable temperature range is 2 30, but it cannot resist the sudden change in water temperature, and the temperature difference suddenly exceeds 2 3 Koi will be uncomfortable, and 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.

Koi fish are kept in aquariums or fish ponds because of their body shape due to the environment. Do not put too many decorations in the aquarium to avoid damaging the fish. Aquarium breeding koi generally choose to be raised in the body length of 20cm below, too large often because the space is too small and affect its normal activities, the best conditions are equipped with filters, water lifters, thermostatic heaters and other facilities, the formation of a complete water circulation system, can effectively maintain water quality.

Koi fish are also not suitable for growing aquatic plants like ordinary ornamental fish, because they will eat the grass, they have a habit of digging, and they tend to get all the grass out of the bottom sand.

Koi have relatively large requirements for aquariums, and the general aquariums used include large cabinet aquariums and round tank aquariums, both of which have their own advantages in breeding and ornamentation. Square aquariums allow players to view from the side and appreciate the overall beauty of the fish, while tank aquariums generally enjoy the bright colors of the koi from the top. From the perspective of breeding, square aquariums can generally be equipped with advanced facilities such as automatic filtration systems and water pumps, which are more convenient for players to raise, while tank aquariums generally use regular water changes to maintain water quality.

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

1. Feed according to the growth stage of koi

During the growth process, koi fish need to be fed scientifically according to their growth stage. Generally speaking, the growth of koi fish is divided into three stages: juvenile stage, rearing stage, and maturity stage.

In the juvenile stage, high-protein feed, such as fishmeal, should be given to help koi fish strengthen their immunity and promote their healthy growth. During the rearing period, the feed ratio should be gradually adjusted, and an appropriate amount of carbohydrates and fats should be given to help koi maintain physical strength and increase fat content. During maturation, protein and fat content should be reduced and fiber and mineral intake should be increased to ensure healthy reproduction.

2. Feed according to weather changes

Weather has an important impact on the growth of koi fish. In the case of low temperatures, the amount of feeding should be reduced appropriately to avoid indigestion of the fish. When the weather is hot, the amount of feeding should be increased appropriately to meet the metabolic needs of koi.

At the same time, if there are more extreme weather conditions, such as strong winds, heavy rains, etc., it is necessary to suspend feeding and wait for the weather to stabilize before feeding, so as not to cause fish and waste of feed.

3. Feed the fish according to their activity

Koi fish are lively and active fish, and their activity directly affects their digestion, absorption and feeding. In general, the amount of activity of koi fish is related to factors such as water temperature, feed type, and water quality.

In the case of high water temperature, correct selection of feed type and suitable water quality, the activity of koi Changmin is large, and the feeding amount should be increased appropriately to avoid emaciation and lack of nutrition. Conversely, in cases where the water temperature is low, the feed type is not suitable, or there is a problem with the water quality, the amount of feeding should be reduced to avoid feeding problems such as indigestion and diarrhea.

4. Regular and quantitative feeding

In order to avoid overfeeding and waste of fish, regular and quantitative feeding should be adopted. Generally, feed 2-3 times a day, and the feeding time should not be too long, generally 10-15 minutes.

At the same time, the amount of feed should be scientifically adjusted according to factors such as the number of fish, the size and type of water body, etc., to avoid overfeeding, resulting in deterioration of water quality and feed waste.

Domestic koi fish can breed on their own, but certain conditions need to be met. First of all, there is the age of the koi, the male fish must be at least 2 years old to reproduce, and the male and female are preferably more than 3 years. Age meets the requirements, and the surrounding environment must be adjusted.

They need to be sure that the water quality, water temperature, oxygen and light are suitable for them to reproduce successfully. In addition, the ratio of male to female fish should be controlled to about 2:1 so that they can reproduce better.

When raising koi fish at home, many people will want them to breed on their own, and that's okay. Domestic koi fish can be bred on their own, but certain prerequisites need to be met. The first is the issue of age, only after reaching the right age, koi can reproduce on their own.

Specifically, males need to be at least 2 years old to reproduce, and females must be at least 3 years old to reproduce. After meeting the age conditions, there is also the question of whether the surrounding environment is suitable, and only under the right conditions can koi fish reproduce on their own.

Specifically, there are still many aspects that need to be paid attention to. For example, water quality must be kept clean; Another example is the water temperature, which must not be lower than 18 degrees, if the temperature is too low, it will lead to reproductive failure; There are also problems such as oxygen and light, which need to be paid attention to. However, some manual manipulation is also required in the process of koi breeding.

For example, we need to prepare a breeding pond, then put the male and female fish in it in a 2:1 ratio, and then keep the surrounding environment suitable for them to reproduce naturally.

Koi fish generally breed at a fixed time of year. If you breed during the appropriate breeding period, the success rate of reproduction will be relatively high. Specifically, the breeding period of koi fish is generally in April-May, which is the best breeding season, and it is best to let them breed during this period.

Koi fish are large ornamental fish, and in order to secure sufficient space for movement, it is necessary to build large breeding ponds. Koi have high requirements for water quality, there can be no suspended dirt, and there are strict requirements for pH and water hardness. The survival temperature is 0-32, but the most suitable temperature is about 22, and the feeding amount needs to be changed according to the change of water temperature.

Koi fish have a gentle temperament and should be farmed with other fish.

Koi is very beautiful, bright color, changeable pattern, is a large ornamental fish, need to live in a large breeding site, so that koi fish can have enough empty ants to go to the activity, the current koi are artificially reproduced, so when breeding koi carp, we should grasp the pH, hardness, temperature and its living habits of water quality.

1. Water quality requirements for aquaculture.

Koi fish are kept under different conditions from goldfish, requiring higher water quality conditions, and pH between pH 6 is the most suitable. And the water should be clean and transparent, light green, light yellow is the best, and there should be no suspended dirty debris in the water. Generally normal dissolved oxygen in water is 5 7 mg l.

The content of magnesium ions and calcium ions in the water will affect the hardness of the water, the higher the content, the harder the water quality, and koi fish are suitable for living in water with lower hardness. The content of nitrite and ammonia nitrogen in the water will not cause direct harm to koi, so it can be controlled below 30mg L.

2. Temperature requirements.

Koi can survive in cold water, 0 to 32 degrees, but the best water temperature for it to survive is 20 to 25 degrees, which is perfect for it to eat, and it helps digestion, and the growth rate will increase. Reduce the amount of feeding when the water temperature is 15 to 20 degrees, and stop feeding when the water temperature is below 5 degrees. Feed according to the change in water temperature to avoid enteritis caused by indigestion.

3. Life habits.

Koi fish are omnivorous fish, usually eat some plant fragments, algae, small shrimp, earthworms, etc., artificially farmed can also be fed koi feed. Koi are gentle and easy to raise, and like to swim with other schools of fish, and koi fish are used to measure their age based on their scales.

1. To control the 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.

2. It is also very important to change the water regularly, breed koi, and maintain the water quality all the time. 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, you can change a 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. Reasonable feeding, and another important problem is feeding, which requires 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.

4. 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 light is stronger, they can be properly shaded.

5. 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.
