High-efficiency and high-survival-rate fry hatching and breeding device

The utility model discloses a high-efficiency high-survival-rate fry hatching and breeding device which comprises a mounting frame, a hatching tank is arranged on the top of the mounting frame in a penetrating mode, a feeding assembly is arranged in the middle of the inner side of the hatching tank, oxygenation assemblies are evenly arranged on the top of the inner side wall of the hatching tank, and a recycling assembly is arranged at the bottom of the hatching tank. Through the arrangement of the mounting frame and the cooperation of the hatching tank and the recovery assembly, the hatching tank can conveniently collect and discharge feed residues and excrement and meanwhile can conveniently flow water, pollution of feeding to water quality is reduced through the arrangement of the feeding assembly, meanwhile, sufficient oxygen is conveniently provided for fry through the arrangement of the oxygenation assembly, and the fry breeding efficiency is improved. The death rate during fry breeding is reduced, and
