The abdominal opening levers 3d, 3d, which only hold the abdomen, open the abdomen without disseminating the internal organs, and the abdominal opening state is maintained thereafter by the abdominal opening levers 3d, 3d, which move together with the transport device B.

In this way, while the abdominal opening state is maintained by the abdominal opening levers 3d and 3d), the fish body is transported by the general feeding device B with its throat positioned and fixed at a predetermined position regardless of the size of the fish body. At this point, as mentioned above, the tip is devised so as not to cut the abdominal cavity wall, and at the same time as the fish is transported, the tip is inserted from above the base of the stomach into the abdominal cavity, regardless of the size of the fish. The rotary knife 4e with a cover, which descends until it abuts against the wall and immediately rises, cuts off the base of the stomach pouch while leaving a part of it without damaging the abdominal cavity, regardless of the size of the fish.

Next, when the fish being transported in an open state with the base of the stomach pouch partially cut off reaches the viscera removal device F, the throat is positioned and fixed at a predetermined position regardless of the size of the fish, as described above. Regardless of the size of the fish, the clamping levers 2r, 2r descend sufficiently from above the stomach pouch in time with the fish body being transported, and immediately rise, thereby firmly clamping the stomach pouch and connecting it to the stomach pouch, regardless of the size of the fish body. Internal organs other than the kidneys are removed from the abdominal cavity along with the membranes.

In this way, by cutting the base of the stomach pouch, leaving a part of it, and then grabbing the stomach pouch and removing the internal organs connected to it, damage to the ovary can be reduced, and kidney removal and abdominal cavity cleaning can be made easier. It can be implemented to

Next, when the fish body is being transported in an open state with the kidneys remaining, when it reaches the kidney epidermal cutting device G, the tip part is devised so as not to cut the abdominal cavity wall, and the fish body is cut as described above. Regardless of the size of the fish, the throat is positioned and fixed at a predetermined position, and in time with the fish being transported, the tip descends from above the throat until it touches the spine regardless of the size of the fish, and this contact state is maintained during 1ull transport. 2g rotating knife with a cover that rises after maintaining regardless of the size of the fish.
As a result, the epidermis of the kidney is completely cut off regardless of the size of the fish, and the kidney can be easily removed in the next step.

Thereafter, the fish body being transported in an open state with the epidermis of the kidney cut off, when it reaches the kidney removal devices H, H, moves smoothly along the spine regardless of the size of the fish body, as described above. The tip is designed so that it can smoothly escape from the anus position of the open abdomen, and the throat is positioned and fixed in a predetermined position regardless of the size of the fish. The rod-like body 2h for kidney removal and washing descends from above until the tip touches the spine regardless of the size of the fish body, maintains this contact state regardless of the size of the fish body being transported, and then rises to clean the fish body. Regardless of the size, the kidney is completely removed and the abdominal cavity is washed without damaging the abdominal cavity. In this case, if the epidermis of the kidney is not sufficiently cut in the previous step, it will be difficult to remove the kidney only by spraying high-pressure washing water.

The fish body, from which the kidneys have been removed and the abdominal cavity has been washed, is discharged from the transport device B and becomes a highly valuable semi-dressed product.

It goes without saying that the automatic fish processing method of the present invention is not limited to the above-mentioned embodiment using one embodiment of the automatic fish processing apparatus of the present invention.
