In the Netherlands, humans are lending a helping hand (or fin) to fish through an underwater livestream equipped with a digital button, providing entertainment for viewers and assistance for aquatic creatures. Located in Utrecht, the Fish Doorbell camera is stationed at the Weerdsluis lock, a crucial stop for fish migrating to spawn during spring.
Typically, the boat lock remains closed during this time, posing a challenge for fish on their journey. However, the Fish Doorbell offers a solution. Online viewers monitor the livestream and press the virtual “doorbell” button when they spot fish. This prompts the lock operator to open the gate, allowing the fish to continue their migration.
While the livestream provides entertainment, its primary purpose is to aid fish in their travels. By reducing wait times at the lock, the doorbell helps prevent fish from being preyed upon by other animals like grebes and cormorants. Additionally, researchers utilise the footage to track fish species and population numbers in the city’s canals.
Although the livestream can accommodate up to 950 viewers with access to the doorbell at once, exceeding this limit redirects users to a doorbell-free YouTube stream. Nonetheless, the popularity of the Fish Doorbell is evident, with over 200,000 viewers tuning in within the first week, mostly from outside the Netherlands.
Now in its fourth year, the Fish Doorbell operates for around three to four months annually. Updates and highlights from the camera are regularly shared on YouTube. Whether you’re interested in assisting fish or simply enjoy watching underwater antics, the Fish Doorbell offers an engaging and meaningful experience for viewers worldwide.
