“De Visdeurbel,” or in English, “The Fish Doorbell,” has created a fun and easy way for fish from the Vecht to travel through the Utrecht canals. Every spring fish migrate to reproduce, but floodgates block fish from completing their journey. On visdeurbel.nl, anyone can watch the live stream from a camera placed at the gate’s lock and ring a digital doorbell, which sends signals to an operator to open the floodgates and let the fish through.
