Thanks for tuning in and giving the fish a hand. Because of you, thousands of our finned friends made it through.
The fish migration season has come to an end, so the Fish Doorbell is taking a break. The camera is off, the bell is silent, and the fish are finishing their journey. But don’t worry, the bell will be back! Starting March 2, 2026, the Fish Doorbell will be ringing again, and we hope to see you then—ready to help the fish migrate through Utrecht once more.
Every spring, thousands of fish swim through the Oudegracht in Utrecht, looking for a place to lay their eggs. But the Weerdsluis is often closed. That’s where the Fish Doorbell comes in. When you spot a fish on the livestream, press the doorbell. The lock keeper will check to see if the lock can be opened. Together, we help the fish continue their journey. Curious how the Fish Doorbell works, how it all started, and who’s involved?
