Abstract: A device for cutting or shredding fish into chum or bait size pieces while the device is towed through water which operates by water turning a propeller and shaft having cutters positioned along the shaft. Surrounding the cutters is a perforated container, hinged for easy opening, loading of the large pieces of fish and closing, with wings or stabilizers symmetrically affixed to each side. A cutting or shredding operation is effected by towing the device through water causing rotation of the propeller and shaft with cutters affixed inside the perforated container containing large pieces of fish or bait. As the shaft and cutters rotate inside the perforated container, the chum or bait is cut or shredded into small pieces which are then washed out through the holes in the container thereby attracting game fish. The device may be made a multitude of colors thereby additionally acting as a colorful lure to game fish.
