conveyed along the First, the vicinity of the gills is pinched by the pinching member 34, and the ovary Y inside the body is pushed to the caudal side (lower side in FIG. 1). In this state, the head is cut off by the round head cutting blade 31. Since the ovary Y is pressed as described above, it will not be damaged when the head is cut off. The abdomen of the fish F whose head has been cut off is pressed by the pressing member 33, and the ovary Y is removed. The removed ovary Y is stored in a saucer (not shown).
The fish F from which the ovary Y has been taken out is changed by the rotating roller 35 into a posture such that its longitudinal direction is along the transport direction A, and reaches the terminal end of the first transport path S1.

Next, the fish F passes through the second transport path S2.
At this time, since the opposing surfaces 24a and 24b are twisted, when the fish body F reaches the terminal position of the second transport path S2, the posture of the fish body F is changed to a state with its abdomen facing downward.

Next, such a fish body F with its abdomen facing downward is conveyed along the third conveyance path S3 with its both sides held between the opposing surfaces 24a and 24b. In the middle of this third transport path S3, the abdomen of the fish F is first incised by the round blade 37 for laparotomy. FIG. 4 1 shows a sectional view of the fish body F in this state. The fish body F with its abdomen incised is further transported, and the internal organs, black skin, etc. are removed by the gutting pulley 38.
