The invention discloses an ocean caught marine product sorting device which comprises a device body, the bottom end of the device body is embedded and sleeved with a supporting frame, the top end of the device body is fixedly provided with a working table plate, the interior of the device body is movably sleeved with storage equipment, the surface of the working table plate is detachably provided with a screening device, the top end of the working table plate is embedded with a supporting seat, the surface of the supporting seat is movably sleeved with driving equipment, the top end of the screening device is fixedly sleeved with a reciprocating block, and a baffle is integrally formed on one side of the top face of the device body. According to the sorting device, the driving equipment, the screening device and the reciprocating block are arranged and match one another, so that the problem that shellfishes are adhered together and a filter screen is blocked can be effectively avoided, and meanwhile, the reciprocating block can horizontally move forwards and backwards, so that the bidirectional anti-adhesion operation process of the shellfishes is achieved; the separation effect of the device is further improved, meanwhile, the device can treat many shellfishes in sequence, and then the working efficiency of the device is improved.
