A rotating rattle attachment for a fishing bait rig includes a generally conical hollow body member, a lead line tube axially disposed within the body member, and one or more chambers defined by the body member and the lead line tube. Each chamber contains one or more balls, and the rattle has exterior fins to promote rotation as the rig is drawn through the water. The rattle produces an audible sound that will attract a target fish or will stress a bait fish into secreting hormones attractive to the target fish.
