Abstract: Fish slaughter device includes fish positioning device with fish head abutment, against which the fish head abuts temporary stop position by controllable fish slaughter tool. Fish head abutment element is a trigger releasable by a trigger sensor of a controllable trigger, controllable to move the fish head abutment into different trigger positions. device includes a first control actuator with a first actuator, a coupling device, connecting the fish head abutment to the first actuator for adjusting movement into the trigger positions, and an additional second control actuator with a second actuator controllably placeable in at least two fixed trigger adjustment positions. The two actuators are coupled so an adjusting movement of the first actuator is stopped by a coupling impact against the second actuator in a fixed trigger adjustment positions, which brings about an associated trigger position of the fish head abutment.
