How to raise yellow eel, how to raise yellow eel

Hello! Yellow eel can be fed bait can be directly purchased eel feed, river group feed, carp or frog feed, adding earthworms, etc., concentrate and binder to process into soft strip bait. Specific Law:

Crush the fish feed, add animal bait and concentrate such as earthworms after grinding, then add a small amount of binder and an appropriate amount of water and mix well on the machine, use a meat grinder (prepare 3 5 mm die holes, choose to use according to the size of the eel) and twist it into a thin strip of soft strip feed, dry it for a while, gently turn it by hand, and let the longer strip be naturally disconnected. Small-scale eel farming can be used in the way of mixing dough: crushed fish feed to add chopped earthworms and other animal bait, and then add concentrate and a small amount of binder and add an appropriate amount of water to mix into a dough, the compound should be ready for use and should not be stored for a long time.

In order to reduce the labor intensity, we can adopt a new fattening method: first add a small amount of compound feed for domestication, and then directly feed the fish feed. In this way, we can first add the fish feed pellets to the concentrated feed and a small amount of binder, and then pour in the appropriate amount of water and sprinkle them directly into the eel pond to feed the eels.

The dosage should be moderate, so that it is better to eat within 10 minutes, and after the eel has eaten the pellets, then throw animal bait such as earthworms or fly maggots. When there is a shortage of bait, you can feed all the fish feed pellets. --I wish you success!

Aren't yellow eels parasites?

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.

1. Choose a pond with good water quality, no pollution sources, and less external interference. Use bamboo to set up a bracket in the pond, and fix the four corners of the cage on the bracket. A food table is set up in each cage.

Because of the habit of cannibalism, the stocking specifications are basically the same, generally 20 to 50 grams.

2. The stocking time of yellow eel should be selected in April, May, or August to September, so as to avoid the sexual maturity and breeding period of yellow eel from mid-May to July. The most suitable temperature for eel growth is 24 to 28 degrees Celsius.

3. Feeding should be timed, eels are out at night during the day, and it is advisable to feed at 6 o'clock and 8 o'clock in the afternoon. The feed should be fresh, and the feed with freighty mold should not be put in. The feed should be washed before it is put in, and each cubic water body should be soaked with 3 to 5 grams of salt for 10-20 minutes, and then rinsed with water before feeding.

Generally, small trash fish in freshwater are selected, and the daily bait quantity is 3%-5% of the total weight of the yellow eel in the cage.

4. When artificial breeding, due to feeding a large amount of feed, the feces excreted by the yellow eel are easy to pollute the water quality, so it is necessary to add new water frequently to keep the water fresh. Change the water every 7 days and 10 days in the spring, and change the water every 3 days and 5 days in the summer.

The cage should also be disinfected regularly, with 10 grams of bleached powder water per cubic meter of water, and the whole pool should be splashed.

5. After stocking, an appropriate amount of loaches can be stocked in the cage, and the habit of upstream and downstream of the loaches can be used to divert and increase oxygenation, and the residual bait of the yellow eel can be eliminated. A certain amount of silver carp is stocked in the pond to regulate the water quality.

Clean the cage in a timely manner to remove excessive debris and attached algae, and keep the water exchange inside and outside the cage unimpeded. The cages are planted with aquatic plants, water hyacinth, and water peanuts to provide a good place for the growth and habitat of yellow eels. When transplanting water peanuts, it is best to remove the roots and wash them and soak them in 5 salt water for about 10 minutes to prevent locusts and other pests from being brought into the box with the grass.

The cultivation of yellow eel can start from pond conditions, eel seed stocking, feed feeding, daily management, etc.

1. Pond conditions.

The pond for breeding yellow eel should have the characteristics of being close to the water source, fresh water quality, and no pollution source, and it is better if it is a pond with convenient transportation and independent intake and drainage systems. Eel cage rearing, the pond is recommended to be east-west, rectangular, sheltered from the wind and sun, the area is 10 667, the slope ratio is 1:, the bottom of the pond is flat, and the water depth is.

2. Eel stocking.

The stocking size is about 25g tail, and the stocking density is in mid to late May. Before the eel seed is put in, it is soaked in 3% 4% salt water for 10 minutes, and during the bathing process, the injured and weakened eel species are eliminated again, and the size is graded. In addition, the size of stocking in the same cage should be consistent to avoid killing each other due to differences in growth due to different feeding capacity.

3. Feed feeding.

The eel seeds are not fed 3 days before they are put into the box, and they are fed from the 4th day, and the eel is soaked in filtered slurry water. Gradually reduce the amount of slurry water added according to the eating intensity until it is completely gone. Usually within 5 to 7 days, the yellow eel can be induced to eat compound feed normally.

When the yellow eel feeds the compound normally, the feed is fed on the aquatic weeds, and each cage is fixed in 3 4 positions, and it is fed once a day at 5:00 and 6:00 in the evening.

After 10 days, the feeding time was changed to 6:00 a.m. and 7:00 p.m.

4. Daily management.

The water should be changed in time according to the change of water quality, generally every 10 15 days, and the amount of water exchanged each time accounts for 1 3 of the total water volume of the pond to keep the pool water fresh. The cage may be damaged due to quality or damage by predators such as rats, so it is important to check the cage regularly for damage. In addition to regular rodent extermination, it can also be judged whether the box is broken according to the eating situation of the yellow eel.

In case of rainy days, it is necessary to pay attention to the change of pond water level to prevent the pond water ** or water peanuts from growing too vigorously and escaping out of the box.

The habits of the yellow eel

During the day, the eel likes to burrow in the humus mud or burrow in the stone crevices with water on the embankment. It is rarely active during the day and comes out of the burrow to forage for food at night. Nocturnal, the oral eggplant skinfold can be respirated, so it can breathe air directly.

In winter and dry season, burrows are dug to a depth of 1-2 meters underground, and several fish live together. The gills are underdeveloped, and the epidermis of the inner wall of the oral cavity and laryngeal cavity is used as an auxiliary organ for respiration, which can directly breathe air; It can survive when the oxygen content in the water is very poor. After coming out of the water, as long as it is kept ** wet, it will not die within a few days.

Yellow eel is a carnivorous and ferocious fish, mostly feeding at night, can prey on a variety of small animals, such as insects and their larvae, and can also swallow frogs, tadpoles and small fish. The feeding of the yellow eel is mostly a sucking method, whenever it feels a small animal near its mouth, it opens its mouth to suck. It is an omnivorous fish that feeds on all kinds of small animals, is greedy, and eats the most vigorously in summer, and can not eat for a long time in the cold season without dying.

The way to raise yellow eels is to choose a good pond, quiet and sunny. The soil is a hard one, with a mud layer of about 30 cm at the bottom of the pond, which makes it easier for eels to burrow.

The depth of the whole pond does not need to be very deep, except for the mud layer, the water depth is about 30 centimeters, and the depth of the whole pond is less than one meter, so it is more convenient to manage. It is more convenient to enter and exit the water, but the pipeline must be protected to prevent the eel from escaping from the pipe.

If you want to raise yellow eel well, seedlings are very important, and they need to be artificially domesticated to have the kind of yellow eel with dark yellow spots, or the yellow eel with golden spots, which is the most popular in the market. It is also necessary to pay attention to the appropriate breeding density, if it is raised too densely, it is not conducive to the overall growth of the yellow eel. It is best to have a special aerator, if there is no or too few aerators, it can not be raised too densely.

Feeding of the eel:

Relatively speaking, the feeding ability of the very small yellow eel is not very good, and it is easy to die, so especially in the early stage of raising yellow eel, it must be more carefully managed. For example, you can feed them some earthworms, or other bugs.

Then it's better to have a special feeding station, and if the pond is larger, you can build a few more, so that they can come and eat at a fixed point and develop a pattern. The platform can be installed 5 cm below the water, which is also easier to observe, for example, by observing how much feed they are left over from the feed, and then deciding how much to feed each time.
