PREFACE

This paper describes the small-scale culture of the flat oyster (Ostreafolium) in Pulau Langkawi, Kedah (between 1979 and 1980), which was part of a programme aimed at developing oyster culture along the west coast of Peninsular Malaysia.

The trials were initially managed by a Bay of Bengal Programme (BOBP) field biologist with help from the fishermen and their families and with support from the Bay of Bengal Programme (BOBP) and the Department of Fisheries, Malaysia.

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, the Director of Research and Charles Angell for encouragement, guidance - and constructive criticism of the manuscript, and to Ruslan B Shamsuddin for information furnished on the project.
