Abstract: The invention relates to a bait drive unit (1), in particular to be installed in a bait fish (100, 110), and to a bait fish (100, 110) having a bait drive unit (1). The object of the invention is to provide a bait drive unit (1) which, situated in a bait fish (100, 110), imitates even more effectively the movements of a “sick” bait fish (100, 110) and thus promises an even higher yield when fishing. A further object of the invention is to provide a bait fish (100, 110) having such a bait drive unit (1). The object is achieved, inter alia, by a bait drive unit (1), in particular to be installed in a bait fish (100, 110), having an energy store (2), an electromotive drive device (3) and a shaft actuatable via the electromotive drive device (3), in that the shaft (4) is curved in such a way that, when projecting into a plane, the curvature of the shaft (4) does not undergo any change in the sign.
