is an order of carp that belongs to the family of fishes. English name: Oriental weatherfish.
The body is elongated, slightly rounded at the anterior end and laterally compressed at the posterior end. The snout is prominent, the eyes are small; the mouth is small, inferior, horseshoe-shaped. Lips soft and well developed, with fine wrinkles and small protuberances. Head without fine scales; body scales very fine, body mucus abundant. Dorsal fin without hard spines, starting a little in front above the start of the ventral fin; caudal fin rounded, with narrow, flat leathery folds ribbed above and below the caudal peduncle. The body is grayish-black with many small black spots, and the body color often varies depending on the living environment.
The loach prefers to inhabit the bottom layer 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. Loach can not only use the gills and skin breathing, but also has a special intestinal respiratory function; when the weather is hot and stuffy or the bottom of the pool silt, humus and other substances decay, causing severe oxygen deficiency, the loach can also leap out of the water, or rise vertically to the water surface, with the mouth directly into the air, and by the intestinal wall of the assisted respiration, when it turns its head slowly dive, the exhaust gas is discharged from the anus. At this time, the loach in the entire body of water are rising to the surface of the water inhalation, one after another, so the Western Europeans have it "climate fish" said. Winter cold, the water body dries up, the loach will be drilled into the mud, relying on a small amount of water to keep the skin from drying out, and rely on intestinal respiration to maintain life. When the water rises in the following year, it will go out again. Because the loach's ability to tolerate low dissolved oxygen is much higher than that of ordinary fish, it survives for a longer time after leaving the water.
Except for the western plateau area, there are fish growing everywhere from south to north in China.
