Eel farming methods, eel farming techniques

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.

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.

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.

The eel breeding technology includes pond conditions, pond disinfection, purchase of eel fry, control of feeding amount, disease prevention and control, etc.

1. Pond conditions: The fish pond should be located in a place with sufficient water source, excellent water body, convenient inlet and drainage pipes, and ventilation in the morning sun. The total area of the pond is generally 5 30 square meters, and the depth of the pond is 70 100 cm.

The pond should be built in an east-west direction, and the soil of the pond should be soft and appropriate. Dig an inlet pipe at the relatively high end of the pond and leave an outlet at the lowest point on the opposite side.

2. Disinfection of the pond: use lime powder to clean the pond and the amount of quicklime powder used. Dry Qingtang is 80 to 100kg per mu. Wet clear pond 150 to 200 kg.

3. Buy eel fry: eel fry is best to choose sunny day seedlings, shrimp seed back, should be the size of the difference, eliminate red seedling, save a healthy life eel species, specifications and models, a catty of 30 tails.

4. Control the amount of feeding: the normal feeding amount of yellow eel is calculated according to fresh material. The daily feeding amount is 8%-10% of the body weight of the yellow eel, and the daily feeding amount is the body weight of the yellow eel according to the compound feed.

5. Disease prevention and control: The prevention and control of eel disease should be prevented by green ecology and assisted by drug prevention and control. When building ponds, it is necessary to pay attention to the disinfection and sterilization of the ponds, and the fish fingerlings should be soaked and disinfected before free-range.

Feed concentrate should be designated to feed, and the residual bait should be removed in time. The special tools used in the production process should be disinfected and sterilized frequently, including 2 to 3 times a week.
