Conference paperS Sahavacharin - In TU Bagarinao & EEC Flores (Eds.), Towards sustainable aquaculture in Southeast Asia and Japan: Proceedings of the Seminar-Workshop on Aquaculture Development in Southeast Asia, Iloilo City, Philippines, 26-28 July, 1994, 1995 - SEAFDEC Aquaculture DepartmentCoastal aquaculture in Thailand has expanded rapidly in both area and production in the last decade. The important cultured species are the shrimps (Penaeus monodon and P. merguiensis), sea bass Lates calcarifer, groupers Epinephelus malabaricus and E. tauvina, green mussel Perna viridis, horse mussel Modiolus senhausenii, blood cockles Anadara granosa and A. nodifera and the oysters Crassostrea belcheri, C. lugubris and Saccostrea commercialis. The total production from coastal aquaculture in 1991 was 230,444 tons, consisting of 70.3% shrimp, 28.8% mollusks, and 0.9% fishes. The seaweeds Gracilaria spp., pearl oysters, scallops, and abalones are cultured on a pilot scale in some places. Hatchery technologies have recently been developed for groupers, oysters, scallops, and abalones. Expanded aquaculture has had some adverse effects on the environment and has also suffered from the environmental changes and conflicts due to other sectors using the same water and other resources.
Conference paperP Sungkasem & S Tookwinas - In F Lacanilao, RM Coloso & GF Quinitio (Eds.), Seminar-Workshop on Aquaculture Development in Southeast Asia and Prospects for Seafarming and Searanching; 19-23 August 1991; Iloilo City, Philippines., 1994 - SEAFDEC Aquaculture DepartmentSeafarming is undertaken in the coastal sublittoral zone. Different marine organisms such as molluscs, estuarine fishes, shrimps (pen culture), and seaweeds are cultured along the coast of Thailand. Seafarming, especially for mollusc, is the main activity in Thailand. The important species are blood cockle, oyster, green mussel, and pearl oyster. In 1988, production was approximately 51,000 metric tons in a culture area of 2,252 hectares.Artificial reefs have been constructed in Thailand since 1987 to enhance coastal habitats. Larvae of marine organisms have also been restocked in the artificial reef area.
Conference paperMN Delmendo - In F Lacanilao, RM Coloso & GF Quinitio (Eds.), Seminar-Workshop on Aquaculture Development in Southeast Asia and Prospects for Seafarming and Searanching; 19-23 August 1991; Iloilo City, Philippines., 1994 - SEAFDEC Aquaculture DepartmentThe paper reviews developments in Seafarming and searanching in the Philippines. Seafarming activities concentrated on seaweeds and molluscs, technology for which are already widely practiced. In Seafarming of oysters and mussels, technology is mature but only applied in traditional sites. As such, the quality of products and consumption is low due to known pollution of oyster and mussel farming areas. Seafarming of giant clams is just beginning. Hatchery techniques of producing juveniles are being refined for mass production and seeding of reef areas to enhance giant clam population. Seafarming of marine fishes is also practiced but constrained by the lack of seed stock. Sea cage fanning operators mainly depend on wild-caught fry and juveniles although the hatchery technology for sea bass has been developed. There is more research work to be done to mass-produce fry and juveniles for Seafarming of other fish species. Seafarming and searanching appear to be the future major means of supplementing the production of animal protein by year 2000 as arable land continues to dwindle. Declining arable land area would not be sufficient to produce the food needs of the increasing population. There is great potential for Seafarming and searanching to enhance coastal resources and produce more food. However, there is a need to provide stronger legal and institutional support for these activities to sustain development efforts.
