Salmon Cannon
Really interesting and wondering why this was invented a long time ago.

A Washington state-based company has created a fish-launching device — a “salmon cannon” if you will — but its intent is not for the sheer purpose of watching fish fly.
According to Whooshh, the device’s creator, the fish cannon was created to help salmon and other fish overcome man-made obstacles.
The Verge reported that the fish cannon was specifically created to help Chinook salmon in Washington make the leap over hydroelectric dams that were blocking their migratory path.
According to the company’s website, the hope is that the fish cannon is more efficient, faster (up to 40 fish per minute) and more cost-effective than other methods. The company also said it has little to no height and length limitations. The cannon also gives wildlife departments the opportunity to collect data or tag fish as they pass through the system.
