Book (stand-alone)Small-scale Oyster Culture on the West Coast of Peninsular Malaysia - BOBP/REP/63 1993
Also available in:
No results found.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). -
Book (series)Installation and operation of a modular bivalve hatchery. (Printed version contains CD-ROM) 2007
Also available in:
No results found.Limiting factors such as minimal capital investment, lack of technical support or expertise and available physical space may put severe restrictions on setting up a hatchery. Not all investors have the means or the will to take the risk to support a large commercial aquaculture operation without substantial proof of its production capacity. For these reasons, the setup of an inexpensive modular hatchery may be a simpler option to the start-up of a large commercial operation, or may be sufficient to the needs of a smaller operation. This manual was written for those interested in establishing a bivalve hatchery, with minimal experience in this activity, limited technical support and restricted access to information. The manual stands as an entity, providing not only the technicalities of setting up and operating a hatchery, but also makes some of the scientific background, deemed useful to the aquaculturist, readily accessible. The manual is divided into chapters for each stage of reari ng: broodstock conditioning, algal culture, hatchery, nursery, growout and economic considerations. The first five chapters include both the physical requirements and culture considerations and procedures for the relevant rearing stage. The final chapter on economic considerations provides an insight into the labour involved for each stage of production, along with a list of equipment and supplies, which may be used as a template for a new installation. -
