It’s time again for the yearly fish doorbell!!!
In a canal in the Dutch city of Utrecht, fish are beginning to mass behind a lock called the Weerdsluis. Now, for the sixth year in a row, you can help them get the attention of the lock’s operators. The Fish Doorbell—or Visdeurbel in Dutch—is back.
Started in 2021, this project allows viewers around the world to monitor the feed from an underwater camera. When they see a fish that wants to move through the lock, they can ring the doorbell and alert operators to the finned animal waiting outside.
“The project is a good mix of doing something for nature and for people to join and do something,” says Anne Nijs, an ecologist for the city of Utrecht and one of the Fish Doorbell’s originators. http://spklr.io/6044DhUlp
