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.

Method for removing the bones from fish and an apparatus for carrying

An apparatus forming part of a filletting machine for removing meat from the skeleton of fish in the region of the ribs is described, through which the fish are conveyed with their tails leading and guided by guides which penetrate into cuts already performed for cutting free the belly and back spokes. The removal of meat from the ribs is performed by means of a tool, which comprises a scraping knife arranged on each side of the belly-cut guides and exending in a plane which forms an angle of between 10.degree. and 50.degree. with the guidance plane defined by the belly-cut and back-cut guides.

Device for detaching meat from the skeletons of fish

The invention relates to an apparatus for gaining boneless fish fillets. In a fish filleting machine which processes the fish being conveyed tail first and comprises a belly and back filleting toot, and a severing tool for releasing meat bands on either side of the spinal column in the tail region, a pinbone tool is arranged between the two first-mentioned tools, this pinbone tool comprising circular knives between which a graving knife is arranged for severing the meat strip containing the pinbones immediately after this strip has been cut free.
