Abstract: A hands-free clamping fixture in accordance with my invention for immobilizing a fish or animal carcass to enable the cleaning and/or descaling thereof comprises a base member, and a movable clamping device interacting therewith. The base member has a work surface, and the movable clamping device principally comprises a component of generally U-shaped configuration. This component has a base portion and a pair of arms, and in operation is inverted such that the arms extend downwardly away from the base portion, with the arms being guided with respect to the sides of the work surface. A foot operated arrangement is employed for causing the base portion of the inverted U-shaped component to selectively move into a tightly clamping relation with the work surface, so as to firmly grasp and hold a portion of fish or animal that has been placed on the work surface.
