Fish in the Netherlands are getting help with their annual migration from their human friends on land, who are able to help them ring a doorbell. Aptly called The Fish Doorbell Project, an underwater camera lets people see if fish are trying to get through a gate in this canal in Utrecht. When enough fish are gathered, online viewers can press a doorbell on the project’s website. Inside Edition Digital’s Mara Montalbano has more.
