    Pearls, one of the highly esteemed gems, are very valuable due to the high demand and prices for them. Several countries bordering the Indian and Pacific Oceans and some countries along the Eastern Atlantic Ocean have pearl oyster resources. Many of these countries, particularly those in Asia, are very much interested in pearl oyster farming and pearl culture. Japan stands foremost in the two fields having developed technologies and innovations in the field. The techniques of pearl oyster farm ing and pearl culture are not widely known. There is a need to promote more widely the techniques and relevant information on the bionomics of pearl oysters. In India, interest in pearl culture began at the start of this century. Several studies have been conducted by the Madras Fisheries Department in the 1930s. In 1972, the Central Marine Fisheries Research Institute (CMFRI) took up intensive research on pearl culture at Tuticorin achieving a breakthrough in July 1973 when it produced free s pherical cultured pearls by employing the mantle graft implementation technique. Since then intensive research has been carried out by the Institute on pearl formation, pearl oyster biology and ecology, and hatchery techniques for production of pearl oyster seed. Considerable information of applied value has been obtained. The development of the pearl oyster hatchery technology in India in 1981 opened the way for large and commercial scale culture of this bivalve species. Based on the technica l know-how provided by the CMFRI, a company has been established at Tuticorin to produce cultured pearls.

    This paper describes small-scale oyster culture trials carried out in the states of Kedah and Perak on the west coast of Peninsular Malaysia. Rafts and longlines were found to be economically viable and the technology was transferred to fishermen. Spat of the slipper oyster, Crassostrea iredalei, were transplanted from the east coast of peninsular Malaysia to the west coast sites. Small-scale depuration units were established at farm sites and a series of market promotions successfully un dertaken. Hatchery seed production and remote setting were done by biologists and staff of the Fisheries Research Institute with assistance from temporarily hired field biologists. Artificial spat production was necessary to supplement short supplies of wild spat. Acknowledgement is due to the Director General of Fisheries, Malaysia, Dato Shahrom bin Haji Abdul Majid, for his kind support and permission to publish this paper. Thanks are also due to the Director of Research, Mr. Ong K ah Sin, for his guidance and encouragement, and to Messrs. Ng Fong Oon and Kamal Zaman for their contributions. The trials were undertaken from 1988 till mid-1993 as a BOBP subproject under the regional project “Small- scale Fisherfolk Communities in the Bay of Bengal” (GCP/RAS/ll8/MUL) funded by DANIDA (Danish International Development Assistance) and SIDA (Swedish International Development Authority).
