Fish that currently swim in the Utrecht canals are pike, bream and oride. They enter the city via the Vecht and the Krommerijn. “People who have looked at the fish doorbell also see that all kinds of fish enter the system through the Weerdsluis.

We want it so much possibly stimulate: it’s good but it could be better.”
