You may remember an article about Utah’s fish-stocking method involving an airplane and a hatch.  Well, a recent post on outdoorlife.com revealed that “Washington has one-upped Utah, and is now using a cannon to move fish.”

Apparently, the cannon they use is a “lengthy, flexible vacuum sleeve designed by Whooshh Innovations“, which was, oddly enough, originally used as a method for transporting fruit.  After Whooshh Innovations heard of the difficiculties Washington wildlife officials were having moving fish through dams, they experimented and came up with what is basically a fish cannon.  The fish are sucked through the tube at a whopping 32 feet per second.  Yakima Nation Fisheries has already moved hundreds of spring Chinook through the Roza Dam via this cannon method.
