Why are pearl oysters important to the Tuamotu Archipelago's economy?

Pearl oysters are vital to the economy of the Tuamotu Archipelago primarily because they support the cultivation of black cultured pearls, which are a major industry for the region.12

These pearls, harvested from the black-lipped oyster (Pinctada margaritifera), are of significant economic importance to French Polynesia as a whole, accounting for approximately two-thirds of the country's total export earnings. Beyond their commercial value, pearl oysters, alongside fishing and coconut cultivation, serve as a fundamental resource for the local population living near the lagoons of the archipelago's atolls. Historically, the presence of pearl shell also served as an early driver for trade in the region during the 19th century.123
