Eel certainly everyone has seen, and there are many people have eaten, eel it for the tropical and warm zone fish, in general eel it is particularly adaptable, inhabiting the bottom of the water body. It can be said that in some of the swamp flooded or silt location, is particularly suitable for eel growth. What are the environmental requirements for eel rearing?

Water temperature

The eel is a variable temperature vertebrate, the body temperature changes with the change of external temperature, all the activities and the temperature of the water has a particularly large relationship. The low water temperature leads to stop eating, the water temperature is suitable, the appropriate amount of particularly large, the water temperature is too low, will produce life-threatening, into the hibernation state for several months; the water temperature is too high, drill holes hibernation.

Water pollution-free

Feeding water body at any time there is a fresh water source to make up for, try to expand the pool surface water and air contact surface. Often organize the surface of the water too much aquatic plants, including weeds at the edge of the pool, to avoid their own pollution. In the process of eel feeding, the water color and its change is an important indicator of good or bad water quality. Water color is a comprehensive reflection of the amount and type of suspended plankton in the water. The best water color is green. Water color is too thin white, white spots, water mold, ulcerative diseases are likely to occur; too fat water color black aging, the lack of dissolved oxygen and cause floating head, affecting the use of bait and growth.

Pool water disinfection

Must be regularly splashed with 20 × 10 ~ 6 of lime water, so that the water body ph value to reach more than seven, but also must pay attention to the eel in time to fish out the dead eels, as well as eels with disease, eel treatment, you can also look for a safe and healthy soil, it will be dealt with, to avoid the spread of eel it's disease, so that the soil or the water quality of the secondary pollution, so It will be a threat to the eel's health as well as the disease condition.

Water depth?

The eel doesn't have a swim bladder like other fish, so it likes to rest in shallow water, about 20?30cm deep, and in deeper water, if there are dense aquatic plants, the eel can rely on the water plants to rest in water up to 30cm below the surface.
