In Manihi, the Rahui has brought the lagoon back to life

28/12/2025

In Manihi, in the Tuamotu Archipelago, the rahui - an ancestral practice for managing and preserving natural resources - is now showing its benefits. Introduced eight years ago, this system has profoundly transformed the state of the lagoon and allowed marine life to visibly return.

For the atoll’s fishermen, the results are now clear. "Before, there were no more fish. We had to go far away to fish. Today, the fish have returned. We see big specimens on the reef and in the pass," says Tehitirava, a fisherman in Manihi.

This regulation inspired by Polynesian traditions has become a real guarantee for the future of fishermen, both ecologically and economically.

"We sell our fish in Tahiti. We manage at least three sacks per week. Well-filled sacks can reach 15,000 francs," Tehitirava explains.

This success largely relies on the commitment of the municipality and the determination of the atoll’s residents. "This rahui was difficult to establish," recalls Lyse Haoatai, former mayor of Manihi. "We had to convince people and sometimes oppose those who had their fish traps. Today, tatihi and even marava have returned. It is magnificent."

Thanks to this regulation, the lagoon has gradually regained its natural balance. Among the most visible signs of this improvement is also the return of sharks.

"Their numbers have increased," says Joackim, another fisherman from the atoll. "The lagoon is healthy and there is fish."

For the current mayor of Manihi, John Drollet, the challenge now is to preserve this fragile balance. "We will have to find the right balance: open to earn money, close to allow fish stocks to regenerate."

In Manihi, the rahui now goes beyond the simple framework of tradition. It represents a collective commitment to preserve the lagoon, transmit ancestral knowledge, and ensure the livelihood of future generations.
