Unexpected Creatures Stir Curiosity

A surprising discovery puzzled the workers. They found larger fish, including species never seen in Paris, swimming in the canal’s murky waters. To protect them, experts devised a plan to leave just enough water to keep the fish safe while they figured things out. The team decided to capture, tag, and identify each fish before relocating them to more suitable habitats, as the urban canal was far from ideal.

Draining the canal completely for the cleanup would have made it impossible for them to survive. This unexpected task added a layer of urgency, as rescuing these fish became just as important as the restoration itself.
