About the Fish Doorbell

Every spring, fish swim right through Utrecht, looking for a place to spawn and reproduce. Some swim all the way to Germany. There is a problem, however: they often have to wait a long time at the Weerdsluis lock on the west side of the inner city, as the lock rarely opens in spring. We have come up with a solution: the fish doorbell! An underwater camera has been set up at the lock, and the live feed is streamed to the homepage. If you see a fish, press the digital fish doorbell. The lock operator is sent a signal and can open the lock if there are enough fish. Now you can help fish make it through the canals of Utrecht.

Collaboration

The fish doorbell is a project by the Municipality of Utrecht, Waterboard De Stichtse Rijnlanden and Water Authority Amstel, Gooi and Vecht. Together, those organisations are in charge of water management and quality in the Vecht and Utrecht’s canals.
