Site Overview

The Pearl Farm Site on Manihi offers a unique diving experience where the pearl farming infrastructure has created artificial reef structures that attract diverse marine life to the calm waters of the atoll lagoon, providing an interesting combination of cultural heritage and biological observation. The pearl lines and associated structures have become colonised by marine organisms over many years, creating thriving artificial habitats that support communities of fish and invertebrates that might not otherwise concentrate in such numbers in the open lagoon environment. Schools of snapper form dense aggregations around the pearl farm structures, their golden bodies creating shimmering clouds of fish that patrol the water column above the submerged lines in search of small prey items. Moray eels have colonised the various sheltered spaces created by the farm infrastructure, with multiple individuals occupying favoured hiding places among the submerged equipment. Batfish are regular visitors to the pearl farm area, their distinctive triangular bodies and curious nature making them frequent companions for divers exploring the artificial reef structures. The site provides an interesting window into the pearl farming industry that has been central to the economy and culture of the Tuamotu atolls for generations, allowing divers to observe both the human infrastructure and the marine life that has adapted to living among these submerged artificial structures.

Dive Briefing

"Descend from the boat near the pearl farm structures where the submerged lines and equipment immediately reveal their role as artificial reef habitats supporting diverse marine communities. Schools of snapper form dense aggregations around the structures, their coordinated movements creating mesmerising patterns as they patrol for food among the submerged lines. Moray eels occupy sheltered spaces within the farm infrastructure, with some large individuals extending from their hiding places to investigate the current. Batfish cruise around the structures with their distinctive swimming style, often approaching divers with apparent curiosity. The pearl lines themselves are covered in marine organisms including sponges, tunicates, and algae that create living surfaces supporting the diverse community of associated species. Take time to appreciate the unique combination of human industry and marine ecology that defines this site and provides insight into the pearl farming heritage of the Tuamotus. The shallow depth allows extended bottom times for thorough exploration before a leisurely ascent."
