The invention relates to a method for obtaining skin-free belly flaps of fish and to a device for implementing the method. On the basis of a filleting machine which processes the fish, which is conveyed tail-first and has a belly-filleting and back-filleting tool, a rib-separating tool which takes the form of a scraping tool and a severing tool for separating the bands of flesh on both sides of the spinal column in the tail region, the arrangement of a cutting device between the two former tools and of a further separating device immediately downstream of the rib-separating tool is described. By activating the latter tools at the moment of arrival of the belly cavity end, the cutting elements of the tools, which include a knife blade, penetrate the flesh to be filleted until the undersurface of the skin is reached and divide the latter as conveying continues from those parts of flesh which cover the ribs and the lateral spinal column extensions of the skeleton, i.e. the belly flaps, so that the latter are skinless once they have passed the rib-separating tool.
