Fish Doorbell in Utrecht

Fish in the Netherlands travel upstream to spawn in the spring, but unfortunately for the fish in Utrecht, the boat lock on the river through the city is closed in the spring. Ecologists put a camera on the bottom of the lock, and viewers around the world can watch a livestream of the camera and, when they see a fish, press a doorbell to open the lock allowing the fish the opportunity to continue swimming upstream to their destiny.

This is a YouTube livestream of the doorbell camera, which is what gets shown to viewers on days like today when more than 900 people are watching the camera, but fear not because they post a weekly highlight reel.

You probably missed the pike and ide, but perch, common roach, and freshwater bream should be swimming by around now.

PS the domain is visdeurbel.nl, which translates into English as Fish Doorbell, and I think Dutch is a very charming language.
