Each Spring in Utrecht, The Netherlands thousands of fish swim through canals and waterways, searching for a place to spawn and reproduce.
In the heart of the city you will find Weerdsluis, a manually operated lock. When the gates are closed, fish are forced to wait, wasting valuable time and energy – making them easy prey for birds and predatory fish.
To help the fish, an underwater camera is installed at the lock. If fish appear on screen, you can press the doorbell! This alerts the lock keeper, who will open the lock when many fish are waiting.
You can “ring” the Fish Doorbell from early March to late May. Migration really picks up starting in early April.
Here is the link to watch the live stream and press the doorbell.
Below is a video from a past year that will give you an idea of what you will see .
