Stunning device for killing small animals or fish










Image Number 3 for United States Patent #6769976.

Stunning device (1) for small animals or fish of 2 kg to 7 kg weight comprises pneumatically powered piston assembly (2) which includes an extendible piston. Support (3) for piston assembly (2) includes base member (4) and multi-component trigger (22, 23, 24, 26). Piston assembly (2) is positioned to define a space between base member (4) and head plate (21) for receiving the head (27) of the animal. When the piston is activated by head (27) contacting plate (22), it extends and strikes head (27) just behind and/or between the eyes with sufficient force to kill the animal with a shock to the brain, but without affecting the external appearance of the animal or fish. The piston extends only once and then retracts, and trigger (22, 23, 24, 26) is reset by removing head (27) from device (1).
