Fish with migration paths blocked by a dam can be shot over the top via the Whooshh Passage Portal technology after being sorted by artificial intelligence.
Whooshh Innovations is a Seattle-based company that is developing better technology to help fish migrate over dams. The Whooshh Passage Portal is their latest all-in-one system for fish passage.
Dams block rivers to create hydropower, which is a source of sustainable energy, but they stop fish being able to swim back upstream to where they spawned in order to reproduce.

"New ways of thinking are needed for this problem," Mike Messina, a director at Whooshh Innovations, told Dezeen.
"Where we have seen so many other fields benefit from clever design and technological innovation, when it comes to fish passage the technology has remained the same for 60 years." The modular, portable system offers a faster and less arduous alternative to fish ladders or fish being transported in tanks by trucks or helicopters.

Fish swim into the system mounted on a floating pontoon via a ramp, which then slides them back down into a scanner.
The scanning machine takes 18 rapid-fire images, measuring the length and girth of each fish to determine whether they are from a hatchery or wild, or even an invasive species.
The artificial intelligence (AI) sorts the fish accordingly, with invasive species released, and the remaining fish routed according t...
