The Fish Doorbell is an innovative and quirky project that allows people worldwide to help fish pass through the Weerdsluis lock in Utrecht. An underwater camera streams live, and when viewers spot fish waiting to pass, they press a virtual button that alerts the lock operator to open the gates. This creative project combines environmental conservation with community engagement.
