ABSTRACT:
A fish eviscerating apparatus employs at least one rotating brush for removing viscera from a beheaded, belly-slit fish. Bristles of the at least one brush have a length and stiffness which, when combined with a predetermined brush holdown, force, are effective for removing a predetermined portion of viscera. A water jet may be integrated with the brush for aiding the cleaning of the fish body cavity. In one embodiment, one rotating brush is controlled to contact the forward end of the body cavity with a stiff holddown force for removing the fish swim bladder and assorted viscera in the vicinity thereof and a second brush with softer bristles is controlled with less stiff holddown force for contacting and cleaning viscera and other debris from substantially the entire body cavity. A water jet cleans a dark, mucous-like liner from the inner surfaces of the belly flaps of the fish. Initial abrasion by the rotating brush, or branches, aids the cleaning action of the water jet. A pressure roller forces the dorsal fin of the catfish through a slot. A cutting knife is timed to remove the dorsal fin without sacrificing a significant amount of flesh. A snaggle, having a plurality of backward-pointing pins on its inner surfaces, engages and pulls free an intestinal fragment to complete the cleaning of the fish.
