The Fish transportation Tube
We’ve all seen cannons on pirate ships or at the circus, but a fish cannon? A frictionless transport system originally developed to move fruit by Whooshh Innovations of Seattle, the “fish cannon” has been adapted to quickly move fish migrating upstream in the Washougal River to transport trucks operated by the Washington Department of Fish & Wildlife. The system can be used to bypass dams, fish ladders or to help fish reach their spawning pools.
Not technically a cannon, pressure is used to push the fish through the tube while keeping it moist, where it emerges from the end of the transport tube directly back into the water. After a few seconds in a tube, and hundreds of fish can be safely relocated in a few minutes. Where are the human version? It would be a delight to commute!
Who says innovation is dead?
