How to breed eels, eel farming methods

1. Scientific stocking of eels as ectothermic animals, as long as the water temperature is 10-32, they can be stocked throughout the year.

2. Before entering the pond to prepare the eel into the pool, a small amount of fermented and rotted organic fertilizer can be applied to breed aquatic animals such as mosquito larvae, silk earthworms, aquatic insects, etc., or snails or loaches can be put in the pool.

3. After 1-2 days of short-term adaptation, the bait can be fed, and the amount of bait is generally 2%-10% of the total weight of the fish. The amount of bait should be increased or decreased according to the water temperature, bait quality, water quality and so on. Generally, the bait is cast once a day.

4. Adjust the water level and water qualityBecause eels can breathe oxygen directly in the air, they need to often stick their heads out of the water. Therefore, the water level of the fresh fish pond should be shallow.

Fifth, the timely screening pond eel species is very competitive, the same size of the fish in the pool, after a period of feeding, the specifications will be uneven, in the long run is not conducive to the increase of production.

6. Prevention and control of fish diseases: The eel pond must be disinfected with quicklime or bleaching powder before releasing seeds.

Seventh, do a good job of protection work, the eel pond is small and shallow, and when the water is new, it is necessary to prevent the overflow of fish from escaping.

1. Site selection: Choose a pollution-free site for breeding yellow eel, and use cement to build a rectangular pond with a depth of one meter and an area of 15 square meters.

2. Feeding management: feeding every 3 days during the breeding period, mainly animal feed such as earthworms.

3. Disease prevention and control: provide pollution-free feed for yellow eel, and feed it regularly and quantitatively.

The eel culture method is to use the guess front method of cage culture for yellow eel culture.

The main advantage is that the water flows through the mesh holes, so that the box forms a living water environment, so that the water quality is fresh, the dissolved oxygen is abundant, and high-density intensive culture can be implemented. A few days before the stocking of eel seeds, the water quality should be properly cultivated, so that the water color is thick, and the transparency is about 15cm, so that the invasion of yellow eels by the grasshopper mites in the pond can be controlled or reduced.

The cages can be set up side by side in the pond, and a bamboo frame is built in the middle of the two rows of cages for people to walk and feed management. The setting area of the cage should not exceed 50 of the total area of the pond, otherwise it is easy to cause water quality deterioration. Aquatic weeds, preferably water peanuts, are placed in the cage, and their coverage area should occupy 90 95 of the cage area, providing a good environment for the growth and habitat of yellow eel.

Eel feed feeding

In order to meet the needs of the life activities of the yellow eel, animal feed and full price compound feed should be fed, and less or no plant-based feed should be fed. At the same time, the eel eats feed with a certain degree of fixity, changing the type of feed, and the eel is difficult to adapt to and refuses to eat for a while, which will affect its normal growth. Therefore, in mixed feeding, the feed should not be changed frequently, so as not to cause a lot of feed waste and increase the cost of feeding.

Set up a food table in the fish pit and feed it in the evening. The amount of feeding should be eaten in the early morning of the next day without leaving any residual bait.

The bait is mainly artificially cultivated earthworms, and when earthworms are scarce, tadpoles, fly maggots, snail meat, small trash fish, etc. are fed. The excrement of loaches and yellow eels can be absorbed by lotus roots in the lotus root pond, which is beneficial to the growth of lotus roots, and the water quality in the lotus root ponds is also purified.

Where there is a heat source, so that the pond water is kept at 25-30 all year round, the eel can avoid hibernation and grow all year roundTechnical measures for artificial breeding of yellow eels: selection and stocking of stocking eel species and eels, feeding and management, and prevention of escape

Management of yellow eel breeding: Feed palatable bait, often add new water, create a suitable environment, pay attention to the prevention and control of eel disease, and the wintering of yellow eelYellow eel disease technology and control, several common diseases of yellow eel

Yellow eel is also known as eel, long fish, etcThe growth rate is fast, generally 10 cm in a month, and the body length can reach 300 grams in 9 months, that is, it reaches the size of commercial fish. Yellow eel is especially suitable for artificial breeding in rural areas, and it is a good way for farmers to get rich

Should choose sufficient water sources, the four seasons of the sunrise place, in terms of water quality, is the key technology of breeding yellow eel, must be frequent water change, maintain good water quality, spring and autumn 3-5 days to change the water once, summer 1-2 days to change the water once, the water depth is not less than 10 cm, the injection water temperature can not exceed 5, so as not to cause death due to the sudden drop in temperature.

1. Selection: To breed yellow eel, choose a pollution-free site, and use cement to build a rectangular pond with a depth of one meter and an area of 15 square meters. 2. Feeding management

During the breeding period, it is fed every 3 days, mainly with animal feed such as earthworms. 3. Disease prevention and control: provide pollution-free feed for yellow eel, and feed it regularly and quantitatively.

Site selection to breed yellow eel to choose a good soil, sufficient water, pollution-free site, and the use of cement to build a pond, the depth of the pond is kept at about 1 meter, the area of a single pond can be controlled within 15 square meters, and the pond is best built as a rectangle, easy to manage.

Feeding management in the process of breeding yellow eel, can be fed every 2-3 days, feeding time in the morning of each day, feed to earthworms, tadpoles, frogs, fish and shrimp, mosquito larvae, etc., or provide artificial feed, and after the water temperature is lower than 5 degrees, to stop feeding.

Disease prevention and control during the growth of yellow eel if you eat putrefined bait or starve for a long time after sudden overeating, it will lead to digestive tract infection bacteria, enteritis disease, so during the breeding period to choose clean, mildew feed, and to regularly feed the eel, strictly control the amount of feeding.

1. Construction site: Ponds with a water depth of more than one meter should be used for breeding yellow eels, and clean and pollution-free water should be used for water quality.

2. Put fish fry: disinfect the pond with quicklime, and then put the yellow eel fry in the pond.

3. Bait preparation: use earthworms, tadpoles, fly maggots, etc. to prepare feed.

4. Regular inspection: sprinkle quicklime every 10 days.

Answer: There are cage culture, rice field culture, pond culture, and soilless culture, and yellow eel is an omnivorous fish based on animals. 1. Cage farming The mode of cage farming is a new breeding mode that has emerged in recent years, which is a large-scale breeding mode mainly used in natural waters, and is carried out in the same water area by arranging cages.

Due to the short breeding time of eel, the seedlings are too small to meet the standard, and because the too small ones are females, the survival rate is low. When stocking, it can be used with 3-5 loaches to remove residual bait and clean the cage in the box.

I think eels and loaches have the same place, they both like to live in sludge, the water requirements are not as high as ordinary fish, and they are suitable for the surface layer without water but the soil is slimy, which is relatively easy to raise.

Cement pond eel is divided into soil and soilless two breeding methods, both of which should be planted with water peanuts or water hyacinth, in the hot season to adjust the water temperature and for the eel to rest, can be planted in the whole pond to leave only a small part of the feeding mouth.

The outlet is secured with mesh to prevent the eel from escaping. There are two ways to raise eels in cement ponds, with soil and without soil, both of which are planted with water peanuts or water hyacinths, and the water temperature is adjusted in the hot season for eels to rest.

In terms of selecting land and building ponds, the breeding ponds of yellow eels should have a certain wind resistance, sufficient sunlight and high-quality water sources. According to the number of breeding to control the amount of feed, there is also a special attention to the release of fry.

Keep the pond water at 25-30 all year round, and eels can avoid hibernation and grow all year round. Yellow eel breeding technology Technical measures for artificial breeding of yellow eel: stocking eel species and eel selection and stocking, feeding and management, and escape prevention.

Ponds with a water depth of more than one meter should be used for the cultivation of yellow eels, and the water quality should be clean and pollution-free.

Keep the pond water at 25-30 all year round, and eels can avoid hibernation and grow all year round.

9/7/18 - Insulation measures. Eels, which do not have enough commercial specifications in the current year, can overwinter in the original pond and maintain a high water level during the wintering period. Especially when the water surface is frozen, loach culture should be kept above the depth of the water under the ice, and changed by 1 per month

You can put the good stocking in the pond because there is enough thin mud at the bottom of the pond for him to make a hole.

The cultivation method of yellow eel is as follows:1. Reasonable construction of eel ponds: the breeding pond of yellow eel should be selected to be built in a sheltered from the wind and sun, close to the water source, and the area should be controlled at 50-100 square meters, for small-scale farming, such a size is enough, the depth of the eel pond should be 1-1 meter 5, and set up the inlet, drainage pipe and overflow pipe, and use barbed wire to secure and close the seal, strictly prevent the yellow eel from escaping.

Once the pond is built, bricks and stones need to be thrown in to provide a place for the eels to perch.

2. Scientific stocking of eel species: after disinfection and water injection, you can put eel seeds, before restocking, you need to soak the eel seeds with 2-4% salt water for 15-20 minutes to kill the pathogens on its body surface. The size of the stocked eel species should be neat, and the stocking density should be 50-150 per square meter.

In order to keep the water and air unimpeded, it can also be polycultured with loaches to improve the water environment, increase the amount of dissolved oxygen in the water, and increase the yield of yellow eel rapidly.

3. Strengthen feeding management: regularly check the pool water, if you find that the yellow eel is outcropping, the feeding is reduced, it is necessary to change the water in time, and pay attention to remove the bait or debris in the pool, and spread a layer of straw or wheat straw at the bottom of the pool, heat preservation and moisturizing, because the yellow eel is a scaleless fish, susceptible to germs and parasites, so it is necessary to pay attention to disease prevention and control, common diseases are plum spot disease, water mildew, fever, rot skin disease, different diseases, to implement different methods of prevention and control.

The cultivation method of yellow eel is as follows:

1.Build an eel pond.

Yellow eels are highly adaptable to the environment. Some abandoned water bodies that are not suitable for the cultivation of other fish and puddles and ponds that are not suitable for growing crops can be used as eel ponds. You can also choose a watery, ventilated, sunny place to build an eel pond.

Yellow eel ponds are best rectangular from east to west, with a depth of about 1m. The area depends on the scale of the farm, generally 20 50 m2.

2.Selection and stocking of eel fry.

At present, the eel seedlings must be harmless, disease-free, healthy, smooth and golden in color. Generally, about 80 eel seedlings per kilogram are selected. If the eel fry are too small, it will affect their feed intake and weight gain, so they cannot be harvested that year.

The stocked eel fry must be of uniform size and size.

3.Artificial baits.

Yellow eels should be fed regularly, fixedly, qualitatively and quantitatively. It is convenient for us to observe the feeding of the eels and clean up the remaining bait. The bait must be fresh, and the daily feeding amount is about 6% of the eel's body weight.

When feeding, it should be adjusted according to the feeding situation of the eel on the previous day, and it is advisable to have a little surplus after feeding.

The methods of raising yellow eels are:Choose high-quality seedlings. Rapid eel raising should choose a species with dark yellow body color and large black spots, no disease and no injury, sensitivity, and strong escape ability.

Reasonable dense breeding. Conventional culture, stocking about 50 grams per square meter of individuals, the density of about 2 kg is the most reasonable. At the same time, the stocking density of eel ponds with more ponds (such as gully eel ponds), more aquatic weeds, convenient water exchange, and thorough sewage discharge can be increased. Instead, it should be reduced.

The size of the yellow eel is large, and the total weight of stocking can be increased; The size is small, and the total amount of stocking should be reduced. The stocking density of those with breeding experience is large; Inexperienced people have low stocking densities.

Size grading pools. The overall weight gain of large and small eels is low in the same pond or in the same cage, that is, the overall growth rate is slow and the benefit is poor. The general purchase of "unified goods", at least three or more grades of breeding, the more grades, the more conducive to breeding and the overall rapid weight gain.

Yellow eel, also known as long fish, is adaptable, has a strong ability to live, is resistant to hunger, can survive in all kinds of freshwater, and is easy to manage. 1. Build an eel pond: choose sunny open space, fields, and old ditches to build a pond.

2. Selection and seeding: select good seeds, yellow is better, and cyan is secondary. 3. Feeding bait:

Yellow eels are retained in ponds, and because their range of activity is limited, they must be intensively fed for bait. The fed yellow eel eats the river mussel meat, snail meat, small miscellaneous fish and shrimp, livestock and poultry offal and borer, silkworm pupa, food factory scraps, rapeseed cake, and likes to eat artificially bred earthworms, flies, etc. Yellow eel is a carnivorous fish, very greedy, when the bait is seriously insufficient, the yellow eel has the habit of killing each other or eating too big and small, strong and weak.

Second, to check the bait, we should pay attention to the observation of lack of bait, single bait, and mixed bait, and pay attention to the fact that when it rains and lacks bait, the yellow eel is frightened and flees outward, does not eat, and does not enter the hole. Check the condition three times, as long as you prevent it in advance, pay attention to observation. The "three defenses" are:

One prevents escape. The second is to prevent harm, geese and ducks are not allowed to enter the pool. The third is anti-poison, and it is strictly forbidden to put cigarette butts, fertilizers, pesticides polluted or polluted water into the pool.

Hello, glad to answer for you. 1, breeding site: yellow eel to the environment adaptability is strong, to the water body, water quality requirements are not very high, can be used both general ponds can also be used cement pond breeding, yellow eel has burrowing, like dark, like warm and good escape habits, so the choice of breeding site should choose the hole head warm, summer shade, good soil quality, convenient drainage and irrigation place, and can maintain a perennial micro flow, the surrounding pollution-free environment.

2. Eel seedlings: There are two kinds of yellow eels in China, one is the ligament yellow eel of Thailand and Vietnam, this kind of yellow eel has strong fecundity, omnivorousness, and fast growth, but the meat taste is not good, and the market price is low.

3. Feed: animal fresh bait, animal scraps, artificial compound feed. Natural insects can also be used as eel feed, among which animal feed is the best choice for eel feed, because of its high protein content and high conversion.

4. Adult eel breeding technology: to create a suitable environment, aquatic weeds play a key role in the process of re-breeding; Strictly control the selection of seeds, and the quality of seedlings directly affects the cost and quality of breeding in the later stage; The nutritional value required by the yellow eel plays a very important role in the growth and disease prevention of the yellow eel. regular prevention of disease; Strengthen daily management, keep the water quality fresh, the temperature is not stopped, prevent the escape of yellow eels, and prevent and control floating heads.

5. Disease: Yellow eel has evolved and adapted to the natural environment for a long time, has strong disease resistance, and the probability of infection is small, and there are few diseases in the process of artificial breeding, but under high-density feeding, poor management of squid and deterioration of leeches will also lead to the occurrence of diseases, which causes yellow eel diseases mainly caused by: external factors, improper use and cleaning of yellow eel ponds, and poor water quality; Internal factors, such as the eel's own physique, imperfect breeding conditions, excessive density, improper baiting, and the entry of harmful substances.
