There are many conditions for breeding white eels, what are the conditions for breeding white eels?

First of all, we must pay attention to the water source, we must use well water, the temperature of the water should not be lower than 24, we must usually feed some earthworms, screw meat, and some silkworm chrysalis tadpoles, small insects, and then the breeding environment must avoid noise and industrial pollution, we must replace the water in time, and clean up the excrement.

It is necessary to keep the surrounding area moist and pay attention to regular sunshine. Care should also be taken to cultivate in clear water and to provide appropriate ingredients. I have to pay attention to regular spraying to prevent parasites.

First of all, it is necessary to have a very large pond, to have a clean water source, to keep the temperature at about 25 degrees, to spray vaccines regularly, to have enough fodder so that it can be cultivated well.

It is best to raise only one type of fish, or fish with similar habits. Some fish are active and aggressive, so it is not advisable to keep them with the quiet fish, which is easy to be attacked and will easily hang up. I didn't understand anything before and liked to put all kinds of tropical fish.

Polyculture together, water source Water source is the first element of aquaculture. It consists of two aspects: water quality and quantity. The amount of water should be sufficient, and deep well water is commonly used in eel breeding, generally a 2000 square meter cultivation farm, and the water output of deep well water shall not be less than 60 tons per hour; Ponds are the most common way of fish farming in rural areas, especially in mountainous and hilly areas.

A small pond is usually built at a low-lying place at the foot of the mountain or halfway up the mountainside, so that fish can be raised and irrigated downstream during the dry season.

In the daily process of fish farming, we should focus on the water quality, not the fish. Of course, to practice a good eye, you need to fail many times before you can refine it. FeedThe key to feeding is water.

Fish farming is water farming", good water is good for fish. Ordinary tap water must be left to stand for more than three days or aerated for more than one day before it can be used, commonly known as "trapped water". The newly bought fish tank must be left to dry for about a week.

Rice and fish farming is also common. The main fish cultured fish are grass carp and carp, but also crucian carp, silver carp, bighead carp, mrigal and other fish. Before raising fish, the embankment of the paddy field should be widened and heightened, and beaten firmly; At the same time, dig fish ditches, fish slips or fish pits, and set up fish fences.

The so-called fish farming of novices mostly goes to the grass tank, and they will buy aquatic grass mud, bottom sand, and negative grass (in the case of no CO2, the aquarium will recommend this kind of aquatic plants, such as crown and water banyan), landscaping stones, and sunken wood. Fish may die easily in the early stages.

Water is added to the tall glass container to make the fragrant dracaena with a planting basket.

It is advisable for the root system to be watered. Or put the fragrant dragon's blood tree with a planting basket into a plastic bucket or box filled with clean water to nourish and promote roots. Novice fish farming, to prepare a fish tank, you can first prepare a small fish tank, will raise later, and then gradually change to a large fish tank, the small fish tank is best glass tank, do not use plastic fish tank, so as not to affect the growth of the fish smell, novices should first use the naked tank to raise fish.

Generally, you should choose a sunny pool, you can spread some more silt, which is conducive to their habitat, the general water can be kept at about 15 cm, you can also put some seaweed, you can put some minced meat or egg yolk, the reproductive ability of this fish is still very good, and the profit is relatively high, so you can do scientific breeding.

First of all, it is necessary to feed by artificial feed, and it is necessary to ensure that the water temperature is between 22 and 25 degrees, and some aquatic plants can also be planted in this area, and the depth of the water is not too high, and it is not exposed to direct sunlight.

First of all, prepare a relatively open place, the water must be clean and clear, and then there must be a very good drainage system, at the bottom of the pool to a layer of soil in the sea, which can ensure the better survival of the white eel, and then feed the fish must be nutritious.

It is best to choose spring and summer when breeding, and the water temperature should not be lower than 15 degrees or 30 degrees, and the water month must be rich in small fish, shrimp, crabs, crustaceans and aquatic insects, which can provide sufficient food.

The air is very fresh, the environment is very hygienic, the temperature is also high, and there is plenty of water.

Yellow eel has strong adaptability to the environment and does not have high requirements for water bodies and water quality. Yellow eels can be cultured in ordinary ponds or cement ponds. Yellow eels have burrowing habits, like darkness, have a gentle temperament, and are good at escaping.

Therefore, when choosing a farm site, it is necessary to choose a warm cave, good soil quality, convenient drainage and irrigation, slight water in all seasons, and a pollution-free environment. creating a suitable environment that plays a key role in the breeding process of aquatic plants; Strictly control the selection, and the quality of seedlings directly affects the cost and quality of later breeding; scientific feeding; The nutritional value required by the yellow eel plays an important role in the growth and disease prevention of the yellow eel. regular prevention of disease; Strengthen daily management to keep the water fresh and the temperature exceeds the limit, and prevent the eel from escaping and floating head. Not all eels can be harvested for farming and nursery.

Generally, injured or electrocly caught eels are not suitable for artificial breeding, let alone breeding. Therefore, if there is a large number of newly caught eels, the fish and water need to be disinfected to prevent disease.

If you want to raise yellow eels at home, you must first have a good site. It's hard to do if you're just raising it with something like a bucket. There must be a pool, preferably a larger earthen pool.

If there are so many, they can be caged. Yellow eels are hermaphroditic fish. Under normal circumstances, the lower body length is greater than 53 cm for males, and when the body length is 36 48 cm, the male and female account for about half of each other, because the yellow eel in this period is in the transition period, and the body length of less than 36 cm is female.

Of course, this is just under normal circumstances. If the body length exceeds 53 cm in the same body of water, some males will become females during the breeding season. Therefore, if you want to reproduce, it is best to choose the kind with a body length of 36-48cm, which is more cost-effective, and if it is too large, let it grow with confidence.

The water source is safe and the dissolved oxygen is sufficient. It is generally recommended to install an aerator. It is best to breed in cages in underwater ponds.

The temperature and light are not easy to handle, but the cost of the equipment will be relatively large. It is best to choose hollow lotus seed grass for aquatic plant planting, which has loose environmental requirements and is also the favorite aquatic plant of eels. Needless to say, we all know that algae generally choose Cryptophyta, but only Cryptophylum because it likes to grow in still water and is not very strict in terms of light requirements.

Yellow eels have a feature that other aquatic creatures in freshwater do not have, and that is sexual reversal. Yellow eels are females when they do not lay eggs before they reach sexual maturity and become males once they lay eggs. Therefore, in the process of artificial breeding, we must remember to replenish the eel fry.

Inbreeding is a problem in closed conditions of artificial reproduction. Generally, after two generations, it is necessary to change the seed, and it is best to replenish the eel seedlings.

You can foster in a wild pond. Do a good job of escape prevention and drainage facilities. Yellow eels are highly active in the wild, and their main food is small fish, shrimp, screws and other live animals and various insects.

During the spawning season, it is common to use attachments with more water hair reed roots, which can prevent freezing and keep warm. As the water temperature increases, the attachments of the female eel gradually come out of the membrane. Where there are no other aquatic plants, eels choose to lay eggs in burrows to hatch seedlings, but the survival rate is relatively low.

First of all, the temperature around the eel must be appropriate, and the feed should be fed in it regularly, and the density of the eel should be controlled, and of course, the water in the pond should be cleaned up on a regular basis.

First of all, the requirements for the environment are not particularly high, but the water source of these environments must be sufficient, and there are no polluting substances in this place, and the water is relatively convenient to enter and exit.

First of all, the temperature must be kept above 20, and the water source must be clean, and no impurities must be used.

The requirement of breeding is to learn more professional techniques, and it also needs to have a very good environment, and it also needs a very moist soil.

Silver carp, also known as silver carp, silver carp, jumping silver carp, silver carp, belongs to the carp family, is one of the famous four major fish. Silver carp can provide two rich glial proteins, which can not only be used for fitness but also beauty, and is an ideal food for women to nourish their skin. It can raise a little more for the best rough, desquamation, and rich breeding experience according to its own conditions, and raise its own economic interests to the highest.

The water depth of the fish pond shall not be less than two meters, and the organic fertilizer at the bottom of the pond can effectively provide nutrients for the silver carp and promote the growth of the silver carp.

When choosing a pond, we should pay attention to choosing a place that is far away from the city, relatively quiet, and has enough water sources. Because silver carp are timid and will jump around in the pond if they are frightened, try to choose quieter places. Density issues:

The density is too small, and the reservoir area is wasted; excessive density; The size of the fish does not grow; For example, below 1000 mu, the number density of silver carp should not exceed 100, the density between 1000 mu and 5000 mu should not exceed about 80, and the density of 5000 mu and above should not exceed 70.

Choose a place with sufficient water source, clear water quality and convenient drainage and irrigation water to build a pond, the area can be controlled at 10-30 acres, the water depth in the pond is more than 2m, the pond is disinfected with a certain proportion of quicklime before putting the fish fry, and the large-scale high-quality fish fry without disease are selected for stocking, and they are very interested in sour food and bad food, and some will eat grass carp feces, chicken and cow feces. In spring and autumn, they eat a lot of decay bait, and in summer, they have a greater appetite, so they need to provide more feed, and in winter, they don't move much, so they eat less.

Fingerling stocking time and breeding method: generally in May and June, avoid the peak period of the wheel worm in the pond. The stocking method generally adopts polyculture, which can give full play to the utilization rate of water bodies and the economical use of food. A small amount of silver carp and carp can be mixed cultured.

The first and most important thing is the water source. Be sure to keep it sufficient, and the second is feed. It can be combined with some good feed, and it can also be combined with some artificial feed.

It has to be sufficient. The third is the geographical environment, it is best to choose a place without noise and pollution. The fourth is soil.

The fifth is to have a good power system, and the sixth is the transportation and communication field, try to choose a good place. Because there are more of them.

Be sure to have plenty of water. The water temperature should be moderate, not too hot or too cold. If you want to be a regular feed, it must be a fixed feed.

The environment in which white eels are kept must be quiet. Don't have industrial pollution. During the rainy season, it is neither flooded nor drought.

Be sure to choose a place with good transportation, because the white eel eats too much, so it has to be constantly fed. The best quality of the soil is loam.

The breeding technique is to ensure that the water source is clean, and also to ensure that the feed is sufficient**, but also to ensure that the surrounding environment is very quiet, but also to choose a warmer environment, because only when these conditions are met, can the white eel grow better and the meat quality better.

First, it is more appropriate to use deep well water, and the water temperature is controlled at 24 degrees Celsius. second, scientifically prepare feed to ensure adequate nutrition; Second, choose healthy seedlings to reduce the occurrence of diseases.

The water source must maintain a very good water quality, and the temperature must be very moderate, the feed must ensure the quality, ensure sufficient quality, the soil quality must also be maintained a little better, and the geographical environment should avoid some pollution, there needs to be a convenient transportation and power supply system.

When you need to pay attention, you should pay attention to the pond should not have a lot of silt, and you should also set up a protective net to avoid rats or birds from harming it, and the oxygen content in it, regular oxygenation, there is a high fertilizer in it, you can sprinkle some organic fertilizer.

Ensuring that the amount of water is sufficient, and that there should be some fresh food every day, and that there is also a comfortable geographical environment, without noisy sounds, these are all breeding skills.

Raising white eel is also one of the special aquatic product breeding, feeding the appropriate economic income income is higher than that of fish farming, so in rural aquatic product farming, the total number of households raising white eel, in recent years is constantly developing, but there are many farmers who raise white eel are wrong, and there are various reasons for it. However, on technical issues, there are eight key categories.

1. Indiscriminate purchase of seedlings. Many farms in different places to buy to put it bluntly "artificially cultivated" seedlings or other to put it bluntly "high-quality" seedlings, in fact, the collection of wild plant seedlings, and this kind of seedlings due to temporary breeding and multi-stage storage, transportation and other unreasonable actual operations, the survival rate in breeding is 90 100, so when purchasing seedlings, we must carefully investigate and identify. Generally, artificially cultivated white eels should purchase high-quality seedlings locally, which is not only economic development, but also ensures quality.

2. Do not reject types. From the outside, the white eel has dark yellow spots, red spots, light yellow spots, blue gray spots and other species, only the selection of the first two species has a rapid growth rate, artificial breeding can obtain ideal economic benefits.

3. Size group culture. In the same pond, the size of the group raised, the small eel is afraid of grabbing food and its physical fitness is weakened or even killed. When the bait is insufficient, the large eel devours the small eel. Therefore, although the large eel grows quickly, the total output value of the pond is low.

4. The water surface is too deep. Because there is no swim bladder in the body of the white eel, it is not allowed to float and stay in the exposed water surface in different water layers to inhale gas. The water surface is too deep, and the white eel needs to swim to the surface of the water often to inhale, which consumes a lot of physical fitness, and endangers the growth and development of normal daily life.

According to the size of the eel, the water level of pond-raised white eels should be 5 20 cm, and the net cage eel aquatic plants should be filled with all the net cages, so as to give excellent habitat and aspiration standards for white eels.

5. Apply manure to the eel pond. The water surface of the eel is small, and it is very easy to damage the water body and cause diseases when applying manure.

6. Neglect the cultivation of aquatic plants. Aquatic plants can prevent heatstroke for white eel at high temperatures and purify and treat water bodies. Eel ponds without aquatic weeds cannot build a good ecological environment, and raising white eels cannot be successful, or it is difficult to achieve high production economic benefits.

7. Feed "vegetarian" food. Some breeders feed white eels with natural vegetarian meals such as bran, vegetable cakes, bean dregs, white rice, vegetables, etc., and when they are more seriously starved and lack of bait, the white eels will also be swallowed in small amounts, but the nutrients can not meet the needs of the life activities of the white eels, not to mention the growth and development of weight gain, and the white eels will slowly become weak and die of disease for a long time. White eel is a carnivore species that is benthic** and should be fed with animal concentrate feed or full-fare concentrated feed.

8. Frequent material control. It often happens that the breeder often changes the type of bait to feed due to the lack of bait security. White eel concentrate feed should have a certain reliability, suddenly change the type of concentrate feed, white eel can not integrate and anorexia, will interfere with the normal production of all manufacturing growth and development.
