The invention relates to a method for the controlled treatment of headless and gutted whitefish (1), especially saltfish. According to said method, before the fish membrane and main bones are extracted, distal blood residues of the neck are removed by means of a high-pressure cleaning liquid jet. Once the main bones have been cut out, proximal blood residues of the neck on the flesh of the fish can be accessed in the region of the abdominal cavity and removed with cleaning means (708) which protect the flesh. The aim of the invention is to mechanically remove the proximal blood residues of the neck, which vary considerably in size and position, in such a way that the flesh is protected. To this end, said residues are removed in layers. An upper part is removed in a device (8) by means of at least one high-pressure cleaning liquid jet oriented towards the proximal blood residues of the neck, said jet being adjusted in such a way that a residue of the proximal blood of the neck remains in order to contribute to the protection of the exposed fish flesh during the application of the jet. The residue is then removed by means of another flesh-protecting means (7). The device for carrying out the method comprises a cleaning device (708) for the layered removal of the proximal blood residues of the neck, said cleaning device being arranged downstream of the filleting device (6).
