Abstract:
1. A method of separation of a backbone part of a fish to obtain a quality-meat-attached backbone section comprising the steps of: a process of feeding a meat-attached backbone part, which is obtained when filleting the fish into three pieces, to a fin cutter and a kidney cutter arranged in sequence along a lateral end of mutually opposite holding faces of a pair of upper and lower conveyor belts while sandwiching and holding the meat-attached backbone part by the upper and lower conveyor belts in a state that a cut-off head side of the fish is oriented in a conveying direction and that a back side of the fish is oriented to a lateral side thereof, and then cutting off a back part of the backbone part from a back fin of the fish to a tail fin thereof by the fin cutter while controlling a cutting position of the fin of the backbone part relative to the fin cutter at the position of the fin cutter by a first control mechanism, and a process of cutting off the a kidney-attached backbone section of the fish by the kidney cutter while controlling a cutting position of the kidney-attached backbone section relative to the kidney cutter by a second control mechanism at a position of the kidney cutter.
