contribution to water ecosystem with fish doorbell

The ‘Fish Door Zili’ (Visdeurbel) project developed in the Utrecht city of the Netherlands to help the migration journeys of fish. This innovative app, which has been reactivated on March 3, supports to overcome the obstacles in the channels of fish with the participation of millions of people around the world.

How does the blind ring work?]
Weerdsluis water gate, located in Oudegracht Channel in Utrecht, is a critical pass point for fish to reach reproductive areas. But this door is able to create obstacles during the migration period of fish, since the boats are opened and closed for the passage. Fish Doorbell project broadcasting live through a camera placed under water to solve this problem. Followers report the water door officer by pressing a digital ring button when they see fish on the screen. The task also allows the passage of fish by opening the door. [

The ecological significance of the project
The migration of fish is vital for the health of water ecosystems. It protects the balance of water by nourishing with fish, algae and small water creatures. Also some types of fish are considered to be the indicator of water quality, since they can live in clean and oxygen-rich waters. Thanks to the Fish Doorbell project, the migration routes of fish are opened and protected the ecological balance of water.

Global participation and interest
Fish Doorbell, which was originally implemented as a local initiative, became an international phenomenon in a short time. Last year, about 3 million people helped the passage of fish by watching live stream. The trackers pass on the screen to observe fish, which is more active especially in the morning and evening. With the intensiveization of fish migration in April, the number of audiences is expected to increase further.

Transportation of valuable data about underwater biology]
The project not only helps the passage of fish, but also offers valuable data about underwater biology. Thanks to the underwater camera, which can observe when and how often the types of fish pass. This data provides important information about the evaluation of water quality and the health of the ecosystem.

Fish Doorbell offers a stunning example of how technology can be used in harmony with nature. With the participation of people all over the world, natural migration paths of fish are opened and contribute to the health of water ecosystems. This innovative project also offers an important contribution to the strengthening of interaction between nature and human.
