From TIME and Cheddar – The pressurized “fish tube” as it called is the environmentally-friendly brainchild of a company appropriately called Whooshh Innovations. Dams can block migration for salmon who need to get where they’re going, but this contraption transports live salmon through the tube and over dams in order to significantly cut down their travel time. This salmon cannon transports the fish between bodies of water. (Via @CheddarGadgets)https://chdr.tv/4ac6a. (more)
