Ecological circulating running water breeding system for loaches

The utility model provides a loach ecological circulation running water breeding system which comprises a breeding tank, an aeration tank lower than the liquid level in the breeding tank and an aeration pipe higher than the liquid level in the breeding tank are arranged on the two sides of the breeding tank respectively to form a three-level gradient, and a water pump is arranged on the side wall of the breeding tank. According to the utility model, the culture tank, the aeration tank and the aeration pipe are arranged to form a three-level liquid level, and the liquid at the lowered liquid level is conveyed to the high liquid level, so that two aeration mechanisms are formed, the flowability of the water body is improved, and the aeration effect is improved. Meanwhile, the oxygen content of the water body is increased, then the loach breeding quality is improved, the loach growth speed is increased, and good development prospects are achieved. 本实用新型提供了一种泥鳅生态循环流水养殖系统，包括养殖槽，养殖槽的两侧分别设置有高度低于养殖槽内液面高度的曝气槽与高于养殖槽内液面
