Abstract: A fish scaling device which is characterized by a flat support designed to receive a fish for scaling, a tail clamp adjustably mounted on one end of the support for clamping the tail of the fish to the support and a head clamp located at the opposite end of the support for immobilizing the head of the fish. In a preferred embodiment a scaling device which includes an electric motor, to which is attached a scaling tool, is used for scaling the fish. In another preferred embodiment a transparent cover is fitted over the support and the fish to be scaled and a slot is provided in a scaling panel hinged to the support, such that the scaler can be moved from side-to-side along the support to scale the fish when the cover is used to prevent scattering of the scales.
