Greece has enacted its first-ever legal framework to protect deep-sea coral ecosystems in the Aegean Sea. This initiative targets vulnerable coral habitats at depths beyond 50 metres, aiming to prevent damage from fishing gear and other human activities.

Prohibited activities near coral sites

Under the new rules, activities such as bottom-trawling, longline fishing, anchoring, and mineral exploration are now restricted in designated areas. The legal measures include clearly defined no-go zones, where marine habitats, including sea sponges and gorgonians, can recover undisturbed.

Scientific rationale

Deep-sea corals are vital for biodiversity, serving as nurseries and shelter for numerous marine species. They are also century-old organisms, growing extremely slowly—some less than a centimetre per year. Even minor disturbances can cause damage that requires decades or centuries to repair.

Implications for dive tourism

For dive travellers, especially those exploring deeper ravines and underwater walls, these restrictions may limit access to some dive sites. However, they also ensure that fragile coral habitats remain healthy and visually striking, safeguarding them for future dive experiences in the Aegean.
