Overview

• More than 100 species have colonized the reef field within a year, and project leads estimate 150–200 may now be present.
• The city placed 50 concrete mini-reefs in five clusters at 8–10 meters depth near the Dic de Recer and added 20 oyster‑shell cages to shelter juvenile fish.
• A press dive recorded over 60 species in roughly an hour, with officials highlighting the unusually rapid colonization.
• The initiative is led by Fundación Barcelona Zoo with ICM-CSIC, the University of Barcelona and UPC, while the port is managed by BSM.
• The area is off-limits to fishing and non‑scientific dives, and claims of cleaner water and CO2 capture will be tested through the new monitoring program.
