More than one hundred marine species restored along Barcelona’s coast
The fifty artificial reefs in the waters of Port Olímpic have been completely colonised by seaweed and other marine life, becoming a refuge and breeding ground for more than one hundred species just a year after their installation.

Invertebrates such as molluscs, crustaceans and sponges, together with fish from families including wrasses, blennies and sea breams, are among the species that have significantly increased their presence in these coastal waters. In this way, Port Olímpic, managed by BSM, has taken another step towards promoting marine biodiversity and helping to regenerate Barcelona’s shoreline, establishing itself as a leading harbour in this field.
Port Olímpic will regularly monitor underwater activity, and scientists will track the recovery of biodiversity and the regeneration of the seabed. The project is led by the Barcelona Zoo Foundation in collaboration with the Institute of Marine Sciences (ICM) of the Spanish National Research Council (CSIC), the University of Barcelona (UB) and the Polytechnic University of Catalonia-BarcelonaTech (UPC).
In recent years, several initiatives have been undertaken to transform Port Olímpic into a renewed and sustainable space that combines community sailing, the blue economy, gastronomy, culture and family leisure.
