ABSTRACT:
A method for automatically cleaning fish such as cod comprises gripping the fish and subsequently cutting it open, first transversely behind the head from the belly of the fish and subsequently in its longitudinal direction along the belly, and finally removing the entrails. The method is characterized in that the fish is gripped in its eye sockets with its belly upwards and being held rotatably substantially about an axis extending therethrough, that the fish is displaced parallel to its axis and is moved with its back supported towards a chin lifting means, which presses the head of the fish backwards, and past a throat cutting means for cutting the fish transversely, that the fish is then turned and moved further head foremost and belly upwards and further round along a curved descending path, that the fish is thereby bent backwards and moved into engagement with a belly distending means which during continued forward movement of the fish passes into the fish along the inside of the belly, and with a knife which in immediate connection to the belly distending means cuts open the belly longitudinally, that the fish is then moved further hanging down freely with the cut open belly facing forwards, and that the entrails are then pulled out by pulling the fish over an entrails scraping means.
