I have got to get myself one of these. Whooshh Innovations have developed a solution (shown below in the video) to the falling salmon populations. The salmon had been kept from their migrating areas by a series of dams. The obstacles at dams leave them “disoriented” and lost. So enter the “salmon cannon” — a pneumatic tube that can shoot up to 40 fish a minute to up to 22 mph. Apparently, getting shot out of a cannon is less disorienting to the salmon but, come on, who would not want to be shot out of a cannon? It is the ultimately water park attraction for the high-end gill crowd.
The “salmon cannon” sucks fish out of water and fires them over barriers. It is really not much of a cannon (anymore than the Salad Shooter is a real gun). The tube has a soft salmon-loving fabric that creates a vacuum that propels the fish. (I just hope that a restaurant doesn’t latch on to this concept).
Tests at Kalama Falls, Columbia River Gorge and Roza Dam in Washington state reportedly show that the salmon are happy to become fish missiles. So there you have it: the salmon cannon
