SOT, Todd Deligan, Vice President of Fish Transport for Whooshh Innovations (English): "One of our guys asked another as we were standing along the Columbia River whether we could put a live migratory species or not in the tube. And we all sort of chuckled, I think, but then we really realised that’s a possibility. And we did a lot of experimentation and found that the movement of fish is very efficient in our system."

SCRIPT

Slippery fish on the Washougal River, about 15 miles (24.15 kilometres) east of Vancouver, Washington were transported via 'fish cannon' to avoid manmade hazards on the water on Tuesday.

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 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. Previously, unwieldy fork lifts had to be used to carry large containers of water from the edge of rivers up to trucks in order to move fish. Now, a few seconds in a tube, and hundreds of fish can be safely relocated in a few minutes.
