The Salmon Cannon Carries Fish Over Dams

The salmon cannon is a "flexible conduit" that transports fish quickly and safely over obstacles, including dams. The cannon doesn't actually shoot fish out of one end, but deposits them gently into the water after propelling them through its tube. The system was initially developed to transport fruit without bruising it.
