Quirky livestream that lets viewers help fish is a hit with millions

The central Dutch city of Utrecht has installed a “fish doorbell” that lets viewers of an online livestream help fish in their springtime swim to shallow spawning grounds. The website has attracted millions of viewers from around the world with its quirky mix of slow TV and ecological activism. The idea is simple: An underwater camera at a local lock sends footage to a website. When somebody watching it sees a fish, they can send a screenshot to organizers. When they see enough fish, they alert a water worker who opens the lock to let the fish swim through.
