From the link😲

 

Every spring fish migrate upstream, in search of places to spawn. They swim through the centre of  the city of Utrecht. Unfortunatly, the boat lock is closed during spring. You can help the fish.

Do you see a fish? Press the Doorbell!

All the photos are collected. When there are enough fish waiting, the lock will be opened.
