A central axle is directed coaxially of the container and exterior bucket projecting through a lid for accommodating a drill to permit its rotation. The axle includes a central conduit, with exterior ports to effect washing of fish directed within the container, with the ports in fluid communication with a fluid source, such as a garden hose and the like. Interior projections cooperate with paddles mounted to the axle for effecting the descaling of fish.
