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 undertaken. 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 Kah 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). |
