The latest information on pearl farming in Tahiti

Pearl farming is now one of the main sources of aquaculture revenue in the Republic of the Marshall Islands, second only to giant clam mariculture. The black-lipped pearl oyster (Pinctada margaritifera) is found in selected atolls where it is commercially exploited.

There are currently four active pearl farms in the country, successful enough to consider expanding their production. Interest in the sector is growing, with several new entrepreneurs expressing their willingness to invest in this promising industry.

A Major Challenge: Lack of Natural Stock

The main threat to the sustainable development of pearl farming in the region remains the insufficiency of natural pearl oyster stocks. Previous studies indicate that the current stock cannot sustainably support a commercial industry and that there is a high risk of total depletion.

Experiments using natural spat collected from different atolls have produced inconclusive results.

A Turning Point with Hatchery Production

This problem has largely been addressed through the implementation of commercial-scale hatchery techniques, which now make it possible to produce spat for the entire industry.

Recognizing the potential of pearl farming as a primary or supplementary source of income for the local population, public authorities are encouraging the creation of small pearl-farming businesses to diversify the economy and reduce dependence on copra.

They are also putting in place sustainable management systems to preserve marine resources.

Outlook

This monograph provides a detailed overview of pearl farming in the Marshall Islands and outlines development prospects for the coming years, underlining the strategic role of this activity in the island economy.

Since time immemorial, India has been renowned for the beauty of its natural pearls. The country has an abundant supply of pearl oysters, particularly the akoya oyster (Pinctada fucata), found in the Gulf of Mannar, the Palk Bay, and the Gulf of Kutch.

This species is often confused with Pinctada radiata — a common but incorrect identification. The black-lipped pearl oyster (Pinctada margaritifera) is found mainly in the Andaman and Nicobar Islands.

The Beginnings of Modern Pearl Farming

Experimental pearl farming was first attempted in India in the early 1970s under the leadership of the Central Marine Fisheries Research Institute (CMFRI) at its Tuticorin center on the country’s southeastern coast.

In 1972, CMFRI produced its first cultured pearls, marking the official start of this industry in India. The institute subsequently refined hatchery techniques for rearing P. fucata (1982) and later P. margaritifera (1987).

A Growing Sector

Once sea-farming and pearl production techniques were standardized, private entrepreneurs and village associations along India’s coasts began engaging in pearl farming, paving the way for genuine local economic development.

Recent Innovations

This monograph briefly traces the evolution of India’s pearl farming industry and highlights recent innovations, such as the development of land-based pearl culture, which could further diversify production.
