Abstract: A fish filleting kit wherein a gate arm having a plurality of dependent pins holds the fish to be filleted by the tail against a supporting board. A revolving locking arm and a vertical stop hold the gate arm temporarily in place during the filleting process. To permit frequent and efficient sharpening of the filleting knife, the kit includes a knife sharpener attached conveniently atop one end of the supporting board. A ruler is provided on one side of the supporting board to assist in an accurate division of the fillet being carved.
