ABSTRACT:
A method for deboning fish is performed by means of an apparatus in which the fish rumps, with their head end leading, pass tools which initially cut free the belly spokes and ribs, the cutting free of the latter occurring up to the back spokes. These back spokes are then extracted from the back portion of the fish rump by downwardly displacing the vertebral column from the fish path, guide faces having scraping edges being guided in the rib cuts and extending up to the flanks of the back spokes, so that the extracting of the same is supported by scraping-off the meat from the back spokes. A splitting of the fish rump in the plane of the removed back spokes produces a double fillet when the cutting depth of the corresponding severing knife is limited up to the region of the tips of the belly spokes, whereas the gaining of individual fillets of maximum yield is possible by removal of the back fin strip together with the fin holders.
