Supporting Fish Passage with Underwater Cameras
The underwater doorbell camera installed in the canals of Utrecht, Netherlands, is captivating viewers worldwide. This system live-streams the moment fish pass through the closed doors of the canal.
This unique camera system is loved by people from all over the world, including the USA and New Zealand. They eagerly monitor the livestream to determine when fish need to pass through.
Connecting the World of Fish with the Underwater Doorbell
The underwater doorbell project began in 2020.
It was initiated after Dutch authorities discovered fish gathering outside the sluice gates, which are the entrance to the Utrecht canal system. The fish, trying to move upstream for spawning, were unable to pass through when the gates were closed in spring.

Instead of installing expensive structures for fish, authorities installed underwater cameras. The cameras broadcast live footage, and when fish appear on the screen, viewers can press the doorbell to signal staff to open the gates.
Strong Support from Viewers
Since its launch, 'The fish doorbell' website has attracted over a million visitors. However, only 950 people can connect to the live footage at the same time. If the 950 slots are filled, viewers can watch the livestream on YouTube.

Local Community's Reaction
Initially, locals viewed the project with skepticism and amusement, but after witnessing many fish being helped, they recognized its importance and significance.
The project's founder, Mark van Heukelum, reports that over 6,300 fish were assisted in passing through within a year.
"It's truly amazing to see people from the USA, Australia, and New Zealand helping fish in Dutch canals through live footage. I feel immense joy now," says van Heukelum.
Although the project may seem peculiar, it offers an opportunity to focus on life and ecosystems that are usually unseen. This initiative, which started in a small Dutch canal, is inspiring the world.
