Abstract: The invention relates to an apparatus and procedure for extracting bones from fish. The procedure comprises detaching the bones from the meat using vibrations, and then, extracting the bone using only enough traction force in order to pull out the bone, thus preserving its integrity, without damaging the interior and exterior of the meat. The apparatus comprises a vibrations generator, a boning device, and means transmitting said vibrations from the generator to the boning device. In a preferred embodiment, the apparatus further comprises a torque generator including maximum output torque controlling means.
