Documents the presentations at ADSEA '91, the 2nd Seminar-Workshop on Aquaculture Development in Southeast Asia. ADSEA '91 includes reviews of the status of the researches conducted by Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC/AQD) on the following cultured species sea bass, groupers, snappers, milkfish, rabbitfish, mullet, tilapia, carp, catfish, bivalves and the seaweed Gracilaria. Topics on aquaculture development in Southeast Asia and Japan were also discussed. The status and development of seafarming and searanching in different SEAFDEC member countries and their ecological, social and economic implications were also presented. The contributions of the selected participants during the meeting which are contained in this volume are cited individually.

Lacanilao, F.; Coloso, Relicardo M.; Quinitio, Gerald F. The 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.

Lacanilao, F.; Coloso, Relicardo M.; Quinitio, Gerald F. Aquaculture production in Singapore is mainly from Seafarming and is about 2% of total fish consumed. At present, there are 79 licensed floating fish farms located in the East and West Johor Straits that culture popular species like sea bass (Lates calcarifer) and estuarine grouper (Epinephelus tauvina). Aquaculture development is geared towards the establishment of highly intensive fish farms such as land-based systems in agrotechnology parks, smaller brackishwater pond systems, and large-scale floating systems in designated sea areas. Research and development on improvement of farming techniques are on-going.Freshwater aquaculture is focused on ornamental fish production. This is a high value trade with yearly growth of 11 % in 1986-1990. Development of intensive farming systems, improvements in water quality management, disease control, and quarantine are considered important. Research concentrates on breeding and genetics.

Lacanilao, F.; Coloso, Relicardo M.; Quinitio, Gerald F. Significant developments in the culture of tilapias and seaweeds in the Philippines for 1988-1991 are reviewed. The country was the top producer of the Nile tilapia (Oreochromis niloticus) and red seaweed, Eucheuma sp., in the world during the period. Intensification of cage and pond culture of tilapia in freshwater with artificial feeding was prevalent. The National Tilapia Production Program was launched in 1990 and is being implemented in 26 sites of 12 regions in the country. Culture of sex-inversed tilapias (O. niloticus and O. niloticus x O. mossambicus hybrids) in freshwater cages, brackishwater ponds, and sea cages was pilot-tested for the first time. For seaweeds, studies were made on the culture of other economically-important species such as Gracilaria sp. and Porphyra sp. A trial on the integrated searanching of abalones (Haliotis sp.) and giant clams (Tridacna sp.) with Euchema was also conducted.
