The loach, at least 2 winters old to mature, began breeding in April each year (water temperature of 18 ℃), spawning in the water depth of less than 30 centimeters in shallow grass, the output of the egg particles adhering to the water plants or flooded dry grass above. Hatchlings, often live scattered and do not form groups. Artificial reproduction is costly and pointless.

The loach, preferring to inhabit the bottom of static water, often in lakes, ponds, ditches and paddy fields at the bottom of the silt surface layer rich in plant debris, strong adaptability to the environment. Living water temperature 10 ~ 30 ℃, the optimal water temperature of 25 ~ 27 ℃. When the water temperature rises to 30℃, the loach dives into the mud in summer. In winter, when the water temperature drops below 5℃, the loach dives into the mud at a depth of 20-30cm to overwinter. When the water rises in the following year, it will go out again. Therefore, loach breeding, wild fishing, or rearing wild loach seedling-based.
