Thanks for watching and ringing the bell!
Thanks to you, thousands of fish were able to continue their journey. The fish migration season has now come to an end, so the Fish Doorbell is taking a break. The camera is off, the doorbell is silent, and the fish have reached their spawning grounds. The Fish Doorbell will be back on March 1, 2027. We hope to see you again next season to help the fish on their way.
New to the Fish Doorbell?
Every spring, thousands of fish swim through Utrecht’s canals on their way to the Kromme Rijn to spawn. Along the way, they reach the Weerdsluis, a historic lock that isn’t always open. That’s why there’s an underwater camera at the lock. If you spot fish on the livestream, ring the doorbell. The lock keeper receives a notification and opens the lock when enough fish are waiting.
Curious about how the Fish Doorbell works, how it all began, and the people behind it? Read on and discover the story behind the Fish Doorbell.
