The utility model belongs to the field of oxygen supply type fish fry transport cases, and particularly relates to an oxygen supply type fish fry transport case which comprises a transport case body, a connecting assembly is fixedly connected to the inner side wall of the transport case body, oxygen supply equipment is arranged on the side face of the connecting assembly, and buffer structures are fixedly connected to the bottom face of the transport case body in an axial symmetry mode. The buffering structure comprises side plates symmetrically and fixedly connected to the bottom face of the transport box, a sliding rod is fixedly connected between the two side plates, the two ends of the sliding rod are slidably connected with sliding blocks, and hydraulic buffering rods connected with the sliding blocks are arranged on the side faces of the side plates. Through the structural design of a hydraulic buffer rod and a spring in the buffer structure, when the universal wheel is bumpy, a connecting rod pushes a sliding block to slide along a sliding rod to compress the spring, and meanwhile, the hydraulic buffer rod absorbs vibration energy, so that the multi-stage damping function is realized, and the problem that internal elements of the oxygen supply equipment are damaged due to long-term vibration is solved; and the vibration amplitude of the transport box is effectively reduced.
