Can yellow eels survive in brackish water

itself it survives in fresh water.

In general, yellow eels can survive in nature from 0 to 40 degrees!

Yellow eel is more sensitive to temperature, the water temperature is lower than 5 in hibernation, rise to 10 o'clock, move to the surface, caves, start to move foraging, water temperature 15 to 30 is the temperature of feeding, frequent activity, vigorous growth, 18 -28 is the suitable growth temperature, 28 food intake is reduced, 36 is the critical temperature. The most suitable temperature for yellow eels is between 22 degrees and 28 degrees, and when the water temperature is higher than 30 degrees, you should try to cool down with the water body! When the water temperature drops to 10 degrees, the eel begins to stop feeding and go into hibernation!

As for the highest and lowest you asked, there is definitely no accurate number, under normal circumstances, yellow eels can survive from 0 to 40 degrees in nature! The water temperature is below 8 and the eel does not eat, below 5 it begins to hibernate, and 8 15 does not gain weight; Yellow eel is generally suitable for growth at 15 32, the best growth temperature is 25 32, the water temperature is higher than 36, the summer is in the hole, and 40 die.

The eel has a layer of mucus on its body, and the salt will break down that layer of mucus and absorb the water in the eel's body, causing the eel to become dehydrated and die.

Because there is a layer of mucus on the eel, that layer of mucus is used by the eel to protect itself, when the salt is sprinkled on the eel, the salt will decompose the mucus, and the salt will also absorb the water in the eel's body, which will lead to dehydration, and the salt will also burn the surface of the eel's body, which will destroy the protective material on the eel**. In the absence of water and protective substances can lead to the death of the eel.

It is because the yellow eel has a slimy protective layer on the outside, and it relies on this slimy protective layer to protect ** and lubricate its body. If his body touches the salt, this slimy protective layer will be quickly decomposed and destroyed by the salted fish, so that the yellow eel ** will hurt its ** without the slimy protective layer.

The loach has a layer of mucus on its body, which, like the frog, is its auxiliary respiratory system. Sprinkle salt on the loaches and the loaches will die instantly for two reasons.

1.Due to osmosis, the loach loses water rapidly from its body, leading to death.

2.The surface of the body is detached from the water environment, the mucus dries out, the loach cannot breathe, and suffocates to death.

Because there is a layer of mucus attached to the body surface of the yellow eel, it is to protect the yellow eel, as if if the salt is sprinkled on it, it will not only destroy this layer of mucus, but also let the water in the body of the yellow eel be absorbed. In other words, if you sprinkle a little salt on the dish before stir-frying, the moisture will be forced out, which is the same reason.

Yellow eels cannot be salted. Salt water is equivalent to poison for yellow eel, and of course it will die.

Hello dear. If there is salt in the water, you can't raise yellow eels. Because the yellow eel is a fish raised in the river, not seafood, it cannot be salted.

The water quality is required to be clean, and the fish pond should be cleaned and disinfected, and kilograms of quicklime should be used per square meter of water surface to evenly sprinkle the whole pool. After disinfection, fill the pool with clean water. At the time of stocking, the water temperature in the eel fry transport container should not be too different from the water temperature of the slag line in the fish pond (3-5).

Water quality requires certain nutrients, and the suitable water temperature for its growth is 15-30. When the water temperature is lower than 10, stop feeding and enter hibernation; When the water temperature is above 15, normal predation begins; When the water temperature exceeds 30, burrow into the cave for the summer. Dear, remember to pay attention to the real-time weather forecast in advance, take a good mouth to pay attention to protection, improve safety awareness, protect yourself and your family, here the teacher wishes you and your family a happy time.

Yellow eels are not easy to feed with clean water, and in the wild, they live on the bottom of silty water. The yellow eel is distributed in various parts of our country, the body shape is snake-shaped, the length is about 20 70 cm, the fins have disappeared, and there is only one three-edged thorn on the whole body. It is relatively adaptable, and likes to burrow into caves, and the exit of the cave is generally close to the surface of the water, which can allow it to breathe better.

It is relatively adaptable, and likes to burrow into caves, and the exit of the cave is generally close to the surface of the water, which can allow it to breathe better.

The eel is elongated, cylindrical and serpentine, and can reach up to 1 meter in length. The anterior part of the body is rounded and posteriorly flattened, and the tip of the tail is thin. The head is swollen, long and rounded, and the cheeks are raised.

mouth large, terminal, snout short and flattened; The mouth is open at the end of the snout, obliquely lobed; The upper jaw is slightly protruding, and the lips are quite developed. There are fine teeth in the upper and lower jaws and on the oral cavity. The eyes are very small, hidden under the skin, covered by a thin skin.

The gill slit is on the ventral side, and the left and right gill foramen are united on the ventral surface, in an inverted "V" shape. The gill membrane is connected to the gill isthmus. The gills often degenerate, and breathing is carried out by the oropharyngeal cavity and intestines.

There is no structure such as a swim bladder to assist breathing, but a gill hole in the abdomen, the epidermis of the inner wall of the mouth, and the intestines are in charge of breathing, and breathing directly from the air.

Yellow eels are fish.

The body size of the yellow eel is similar to that of a snake, it can grow up to one meter at most, and the head of the eel is rounder, the tail is pointed, the body color is brown, there are no scales, but the whole body is distributed with irregular patterns. Yellow eel is a tropical and warm temperate fish, benthic fish, and has strong adaptability. It lives at the bottom of water bodies and mainly inhabits muddy waters such as rice paddies, lakes, ponds, rivers and ditches.

It can even be found in swamps, flooded fields or wetlands. The length of the yellow eel cave is about 3 times the length of the body, and the hole is curved and crossed. Each cave usually has more than two caves, and the exit is often close to the surface of the water so that it can stick its head out to breathe air.

During the day, the eel likes to burrow in the humus silt, or burrow in the stone crevices where there is water on the shore of the embankment.

Habits

It is rarely active during the day and comes out of the burrow to forage for food at night. Nocturnal, the oral skinfold can be respirated, so it can breathe air directly. When breeding yellow eel, the pool area should not be too large, generally 8 15m2, the pool depth is about 70-90cm, the water depth is 20em, and the bottom mud is about 30cm.

In the pond, a porous circular or polygonal juvenile eel protection pond is built, and the hole is separated from the breeding pond by a small mesh iron net, so that the water can flow freely.

Young eels can enter the protection pool from the mesh, while male and female broodstock eels cannot, thus achieving the purpose of protecting young eels. 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, but with the help of the inner wall epidermis of the mouth and larynx cavity as an auxiliary organ for breathing, they can breathe air directly, and can survive when the oxygen content in the water is very poor.
