The utility model relates to an aerator which can be installed on small non motorized ships. The motor drives the propeller to rotate at high speed, and a negative pressure zone is formed in the water, and a large amount of air is sucked into the water through the aerator body to increase the oxygen content in the water. The ship aerator flexible, high aeration efficiency, good effect, suitable for large area aquaculture sites, not only solve the problem of surface water and oxygen, but also solves the problem, anoxic bottom water, and as the power of the small non motorized boat.
