ABSTRACT:
In a machine for gutting fish, particularly trout and salmon, wherein the fish is guided through the machine in swimming position, and wherein the machine comprises tools for cutting the fish's belly, removal of the intestines, cutting the abdominal membrane covering the blood rim, and removal of the blood rim, one has aimed to provide a tool for cutting said abdominal membrane such that the blood rim is not torn up, and such that the rear part of the abdominal cavity of the fish is not damaged. This is achieved in that the cutting tool for the abdominal membrane consists of a rotary knife disc (4) having a V-shaped circumference portion (4', 4"). When such a knife disc (4) approaches the rear edge of the abdominal cavity of the fish, the fish will be raised by the V-shaped circumference portion of the knife disc, so that one avoids that the knife discs causes damages in the rear part of the abdominal cavity of the fish.
