The white eel is a carnivorous fish. In nature, eel fry mainly feed on planktonic crustaceans, and when they grow up, they mainly feed on small shrimps, crabs, aquatic insects, snails, clams, earthworms, etc., and they also prey on small fishes and the debris of higher plants. In the artificial rearing pool, it should be fed with artificial compound feed. The proper temperature for eel growth is 20-28℃. When the water temperature drops below 8-10℃, it basically stops feeding and dives into the bottom mud or stone holes for hibernation; when the water temperature reaches 30℃, it also stops feeding.

The eel can be built to raise eel pond monoculture, can also be mixed in the fish pond. The monoculture pool requires the ability to prevent the escape, there is a self-flowing drainage and irrigation system, and there is sufficient feed. Generally, each acre of eel seed 0.5 million - 10,000 tails, 1 year output of up to 1-2 tons; mixed farming is mainly to fish ponds in the wild small fish and shrimp for food, each acre can be stocked with 50-100 tails, 1 year can be harvested into the eel 20-30 kilograms.
