摘要

A method and an apparatus for processing fish in the region of their gill cavities, commonly also called throating or gulletting, is described. An unthroated fish is pushed onto a spike - shaped gulletting tool arranged above and transverse to a fish conveying path, whereby the skin extending between the last gill arches and the collar bones is pierced. The gulletting tool is provided on its upper side with a cutting edge and associated with a downwardly movable loading arm situated in its rest position approximately parallel to the spike and having a free end which is situated in the vicinity of the lower edge of the gulletting tool. Upon completion of the piercing action, the fish moved downwardly in the conveyor path by engagement with the gill cavity side of its back bone by the loading arm, and the skin and the isthmus of the fish are severed. The fish may then be processed furhter, e.g. fed to a filletting machine.
