This utility model discloses an aquatic product distribution and storage box, including a box body. A handling mechanism is fixedly connected to the outer surface of the box body, and a protective mechanism is rotatably connected to the inner wall of the box body. The protective mechanism includes a rotating frame rotatably connected to the inner wall of the box body, and a support groove is provided on the upper surface of the box body. The lower surface of the rotating frame is in contact with the upper surface of the support groove. This aquatic product distribution and storage box belongs to the field of aquatic product distribution technology. The aquatic product distribution and storage box uses a filter screen to form a damping barrier through dense mesh. When the water sloshes, the friction between the mesh and the water consumes the wave energy, attenuates the wave peak height, and suppresses water splashing. The duckbill one-way valve utilizes the principle of fluid mechanics. When the water surface fluctuates and water overflows the rotating frame, the one-way valve automatically opens under water pressure, guiding water into the box. When the water recedes, the valve closes to prevent water from overflowing, ensuring a stable water volume inside the box during transportation.
