In a method for removing blood released during filleting from the backbone and the indentations therein in the region of the vertebrae of fish that are conveyed in a row with the head forwards and the belly downwards, the removal of blood is carried out at the same time and in the same place as the cutting of the backbone. The backbone, which is freed of ray bones and rib bones, is guided through a cutting gap and is cut clear on the belly side of the fish over the entire length of the fish as far as the root of the dorsal fin to leave a backbone stump. The fish fillet flesh is covered by covering surfaces which converge at the cutting gap and of which at least two covering surfaces form the cutting gap. Pressurised cleaning fluid is sprayed onto the backbone that is guided between the covering surfaces through the cutting gap during cutting. A device for removing said released blood comprises a backbone cutting device having two backbone cutting circular blades, which are arranged obliquely in an inverted V shape and form the covering surfaces, and having fish guiding means forming covering surfaces that cover the fish fillet flesh. A cleaning device comprises at least one cleaning nozzle aligned with the cutting gap. An actuating device actuates the cleaning device and the backbone cutting device simultaneously. The covering surfaces protect the fish fillet flesh from being sprayed with the cleaning fluid.
Method for removing blood released during filleting from the backbone and its indentations in the region of the vertebrae of fish fed head-first in a row in a conveying direction with belly downwards, each having a torso which is separated from the head, including the collarbone, and at least essentially freed of guts, wherein said removal of blood is performed at the same time and place as a backbone cut such that the backbone freed of ray bones and rib bones is guided through a cutting gap and in this process is cut clear over the entire length of the fish on the belly side of the fish down to the dorsal fin roots to leave a backbone stump, wherein the fish fillet meat is covered by covering surfaces converging at the cutting gap, of which at least two covering surfaces form the cutting gap, and wherein pressurised cleaning fluid is sprayed on the backbone guided through the cutting gap between the covering surfaces while it is cut clear.
