Is eel easy to raise, how to raise eels at home, deep water or shallow water? 20

The artificial breeding of eels mainly relies on special compound feed (available on the market), and adds 50 60 grams of multivitamins (vitamins A, B, C, E) and kilograms of cod liver oil per 50 kg of special feed (cod liver oil should be stopped when the water temperature is below 20 or above 35).

Juvenile eels should be added less, and adult eels should be added more. If there is a temporary lack of special feed, small trash fish, livestock and poultry offal, silkworm pupae and other animal feed can be minced and mixed with flour instead, and its crude protein content must be more than 40%.

Eels are carnivorous fish and are voracious. When feeding, the principle of "four determinations" should be implemented, that is, qualitative, quantitative, timing, and positioning. Ensure the quality of the feed. The prepared feed should be moderately soft and hard (add water to be doubled), fresh and clean, and not deteriorate and rot.

The quality of water is the basic condition that determines the construction of an eel farm. Therefore, the water quality of the water source must be checked from the physical, chemical and biological aspects to determine whether it is suitable for the habitat and growth of eels.

1 Water temperature: Changes in water temperature directly affect the metabolism of fish. The river eel is a warm-water fish, and the water temperature requirement for its breeding growth period is 11 33, and 25 28 is the most suitable. Guangdong, Fujian and Taiwan are the most suitable for eel farming.

2 pH: Most of the water used in eel farms is taken from natural water, which is acidic or alkaline due to the influence of geographical environment. For the growth of eels, the productivity of slightly alkaline water is slightly higher than that of acidic water, and the pH range of water for eel farming is the most suitable range.

3. Dissolved oxygen: The maximum amount of oxygen dissolved in water (i.e., saturation) is directly related to water temperature. If the water temperature is low, the dissolved amount of oxygen is large; There are many phytoplankton in the water, and the amount of dissolved oxygen in the water will also increase.

The amount of dissolved oxygen used in water for eel farming is 5 12 milligrams per liter. Generally, groundwater has a low amount of dissolved oxygen and must be aerated before it can be used.

4 Calcium and silicate: The less calcium ions in the water and the more silicate ions, the higher the fish mortality rate. The ratio of silicate to calcium is not harmful to fish, so it is more advantageous when there is more calcium and more silicate.

5 Biogas and hydrogen sulfide: These two gases are produced when there is a lack of oxygen in the water and a large amount of organic matter decomposes, these gases are toxic and very harmful to fish, and the content of biogas and hydrogen sulfide in the water used for eel farming must be less than gram cubic meters.

6 Ammonia: Ammonia is abundant in surface water. According to Ellis (1944), the ammonia content of water used for eel farming must be less than a gram of cubic metre.

In addition, Biockway (1950) believed that for every 1 gram of ammonia in water, there was a decrease in oxygen in the blood1 7. Therefore, when using groundwater and surface water, it is necessary to know its content and treat it with aeration before use.

7 Iron: In surface water, iron is generally relatively low. Groundwater, on the other hand, tends to have a high iron content and exists in the form of ferrous ions, and once it comes into contact with air, it will act to form 3-valent iron precipitates, which not only consumes a lot of oxygen, but is also not suitable for eel farming.

The iron content of water used for eel farming is required to be less than 1 gram cubic meter, and the most suitable is less than one gram cubic meter.

1. Farm requirements. The selection of breeding sites is one of the most important conditions for eel farming, and it is difficult to breed eels without a suitable farm. The eel breeding site generally needs about 50 acres of specifications, and the farm should be equipped with a water injection system, drainage system, heating and cooling system, aerator and so on, and the eel pond should be planned at the same time.

2. Water quality requirements. Eel farming has particularly high requirements for water quality, preferably slightly acidic, so that the eel is more productive. In addition, the content of heavy calcium, nitrate and this stage, hydrogen sulfide, ammonia and iron in the water should be reasonable, otherwise it will also affect the normal growth of eels.

3. Bait requirements. The feed of eel farming is mainly carnivorous fish, and when breeding, if the bait selection is not reasonable, it will lead to the failure of breeding. In general, we need to have an adequate supply of earthworms or small insects and small fish.

Secondly, fresh fish can be crushed through a meat grinder and fed.

The water temperature should be between 25-28, and the oxygen content in the water should be sufficient, and the calcium, nitrate, hydrogen sulfide and iron in the water should be reasonable.

Eels are migratory and sometimes live in seawater and sometimes in freshwater. Therefore, they are relatively special and can be said to be both marine and freshwater fish. When eels are still young, they live in freshwater such as rivers and lakes.

When they reach a certain age and need to reproduce when they are physically mature, they will go to the ocean to reproduce, which is their migratory habit. <

The eel is a type of fish. If fish are classified in terms of their living environment, they can be divided into marine fish and freshwater fish. The difference between marine fish and freshwater fish is relatively large, and their living environment is very different.

However, eels are more special and cannot be divided into one of them, because they can be said to belong to both freshwater and marine fish.

Eels first lived in freshwater, and their growth and development took place in freshwater such as rivers and lakes on land. When they reach a certain age, they go to the ocean to reproduce. This habit is what we often call the habit of migration.

The process of spawning eels is done in the ocean, and they can only spawn once in their lifetime. This phenomenon is also known as river migration.

As mentioned above, eels have the characteristic of migration. When eels are young, they live in fresh water and can be seen behind rivers and streams. When they reach maturity and need to reproduce, they go to the ocean to breed, and eels can only spawn once in their lifetime.

It can be seen that eels can live in fresh water, and in fact their growth and development process takes place in fresh water. In addition, eels raised in captivity generally live in fresh water, and if they are farmed, they can be used in fresh water, and they will not be unadaptable.

Summary. It doesn't take a lot of water to feed eels at home, just a moderate amount of it, and the tap water you usually drink can be used to raise eels. Eels are also relatively easy to feed, and they can survive even if they don't eat for a month.

The water temperature suitable for eel growth is around 20 to 28. Eel is rich in nutritional value, and the meat of eel contains vitamin A, which can prevent the deterioration of vision and play a protective role. Eating eels also absorbs calcium, which is good for bone growth.

Eel skin is rich in collagen, which plays a role in beauty and beauty.

Raise a little more water at home. , or a little less.

This can be properly put in more water.

The water depth is good, or the water is shallow.

In this case, it is a freshwater fish and does not use much water.

A little more fish water than usual will do.

Summary. Eels are not suitable for keeping at home. Eels are suitable for living in water temperatures of about 12 degrees Celsius, so it is suitable for artificially farmed eels to try to keep the water temperature at about 12 degrees Celsius so that eels can grow faster.

Is eel easy to raise, how to raise eels at home, deep water or shallow water?

Eels are not suitable for keeping at home. Eels are suitable for living in the condition of a water temperature of about 12 degrees Celsius, so Zheng Jihe, who is suitable for artificial eels, should try to keep the water temperature at about 12 degrees Celsius, so that the eel can grow faster.

If you breed it at home, it will be more troublesome because the temperature requirements will be relatively high.

Is osmanthus fish farming possible.

Osmanthus fish can be raised at home.

To maintain water quality, you can feed some small fish appropriately.

Under what water quality should it be farmed?

If you want to keep it for a long time, then you need to choose to let the water flow, and you can make a simple water recycling device yourself.

During the period of raising osmanthus fish, it is best to put it in a darker environment, which will make the osmanthus fish feel safer.

Freshwater eels often hunt at night and feed on small fish, crabs, shrimp, crustaceans and aquatic insects, as well as rotting carcasses of animals, and some individuals have higher plant detritus found in their food. Feeding intensity and growth rate increased with the increase of water temperature, and were generally the highest in spring and summer.

Pond-reared freshwater eels feed less intensely in midsummer. When the water temperature is lower than 15 or higher than 30, appetite decreases and growth slows down; Stop feeding below 10. Dive into the mud in winter and hibernate.

Freshwater eels can breathe and sometimes leave the water, and as long as they remain moist, they will not die.

If you need to breed freshwater eels, the earthen pond of eel breeding requires ventilation and sunshine, sufficient water source, and the area should not be too large, and plant 1 meter wide water floating lotus or water peanut around the earthen pond, and use a fence or mesh fence, so that the eel can be prevented from escaping, and can be shaded, which is conducive to its growth.

Before stocking, the excessive silt in the land should be dug out, the bottom of the pond should be leveled, the ridge of the pond and the inlet and drainage outlets should be repaired, and the pond should be cleaned and disinfected with 100 kg of quicklime and 125 kg per 1000 square meters every 1000 days before the eel is planted, so as to completely kill wild trash fish and predators.

Then 5 days and 7 days before the eels are planted in the pond, the water is filled with meters to a depth of rice, and the water inlet is filtered with a 60-mesh sieve. Finally, apply base fertilizer, generally every 1000 square meters of 300 kg of decomposed pig manure 400 kg, until the water is light green or yellow-brown and then put eel seeds, so that they can eat sufficient natural bait after going down the pool. The water in the pond is deepened to meters in about 15 days.
