A fish doorbell (Dutch: visdeurbel) is a system that allows fish to pass through a closed sluice gate through crowdsourced input when fish are present. The Utrecht Visdeurbel uses a livestreamed underwater camera that allows users to press a doorbell button to notify the lock operator that there are fish swimming in the gracht, and that the lock should be opened. [1] It is designed to aid in seasonal fish migration, [2] as an alternative to a physical fish ladder. The whole meaning for this is to save fish from predators as they all find and eat tons of fish from those waters.
It was deployed for the first time in Utrecht in March 2021, [3] [4] [5] [6] at the Weerdsluis on the Oudegracht. In the first two weeks, it was used 23,000 times.
