[HIGHLIGHTS] “Fish Doorbell”: How a live stream with a digital doorbell helps with fish migration

Anne Nijs is part of a team that runs a so-called fish doorbell in Utrecht. An underwater camera at the Weerdsluis lock lets fish through when they want to.

Only around 1,000 people can use the doorbell at the same time. Users can watch the stream on YouTube, but cannot ring the bell when they see fish. The project is not just about letting fish through, it is also about creating awareness among people, she says.
