ABSTRACT:
In a method and an apparatus for gutting non-decapitated fish, in particular breeding fish such as trout, it is characteristic for the processing that the fish are conveyed with their tails leading in longitudinally aligned conveyor troughs, and the treatment of the fish comprises the processing steps of slitting the belly cavity from the anus up to the region of the belly cavity; spreading the belly flaps and tearing open of the bloodstream; collecting and sucking off the entrails; and tearing off the gullet in the area of the mouth cavity. This processing can selectively be combined with the removal of the gills. For correctly performing this process, the cutting tool for slitting the belly cavity is provided with lateral knife blades, which sever the intestine in the anal region, while the suction nozzle is designed as a clamping mechanism in order to tear off the gullet.
