Abstract: A fish cleaning apparatus is provided which includes a cutting board attached to the first end of an elongate support arm, the second end of which is adapted to be supported upon the frame of a trailer carrying a boat, or other suitable vehicle, such that a fisherman can clean his catch at the boat landing. The cutting board is pivotally mounted to the first end of the support arm so as to be rotated between an open position for use and a closed position for transport and storage. The cutting board is provided with a cutout portion wherein a refuse bag can be mounted for the convenient disposal of fish cleaning wastes. The refuse bag is held in place while in use by a retention member which is slid in a channel defined in the cutting board along the periphery of the opening. Knife receiving slots are also provided in the cutting board.
