Abstract
The invention concerns a method for deboning fish of the mackerel family such as the Thunnus genus, the scomboid type and the like, and an apparatus for performing this method. Fish of this family have belly spokes extending along the full length of the backbone into the area of the belly cavity, so that conventional cutting free of the back and belly spokes will lead to a separation of the ribs from the remaining bone structure. To allow an accurate filetting of mackerel fish with their specific bone structure in the ventral cavity region, the invention suggests a slice of fish meat including the ribs to be cut free automatically by providing a computer controlled tool including a knife with a cutting edge diverging with respect to the conveying path of the fish, and a supporting element, which in combination with the knife allows the ribs to be cut away progressively while respecting the anatomical characteristics of the fish.
