This paper examines farming practices in marine fish cage aquaculture in southeast Asia with reference to feed and feeding. It proposes a range of reforms to improve the economic performance of the sector, including selective breeding, use of hatchery-reared fingerings, modernisation of cage systems, improved feed management and use of dry pelleted feeds, relocation of cages to better quality sites and a greater degree of government and private sector co-operation in research and development.

These are the proceedings of a workshop focussed on grouper culture, but also explored management strategies required to support the sustainable development of seafarming in the Asian region. The emphasis was on technology transfer and management strategies for the benefit of farmers and coastal communities. The workshop included special sessions on diversification of seafarming systems and culture species, the role of seafarming in the livelihoods of coastal communities.

This volume, the third major publication arising from the Conference on Aquaculture in the Third Millennium, contains the information essential to conduct well-informed discussion of sustainable aquaculture development - both at the Conference, as well as after. The information provide basic reference points on the progress, direction and magnitude of aquaculture changes, and the factors associated with these changes, within global, regional, sectoral, thematic and technical perspectives.

Aquaculture Asia Magazine is an autonomous publication that gives farmers and scientists in developing countries a voice. Stories concern the small-scale aquaculture prevalent in the region and the circumstances of farmers trying to make ends meet in an increasingly globalised world. We accept articles on any aspect of aquaculture and the related processing, marketing, economic, environmental and social issues. An RSS feed is available if you wish to stay informed of new issues.

NACA implements collaborative development assistance projects on issues of regional interest. Individual projects draw heavily on the personnel and facilities of participating centres in member states. Projects are essentially implemented by participating centres with the Secretariat acting as a coordinating body. NACA supports technical exchange, capacity building, institutional strengthening and policies for sustainable aquaculture development. Network partners include research centres, member governments, farmer associations, development agencies and the Food and Agriculture Organization of the United Nations.

NACA publishes a wide range of aquaculture publications including technical manuals, workshop proceedings, better practice guidelines and several serials including Aquaculture Asia Magazine, the NACA Newsletter and the Quarterly Aquatic Animal Disease Report.

This training manual on scallop and sea cucumber hatchery and aquaculture techniques was prepared for the Scallop and Sea Cucumber Breeding and Culture Training Course, conducted by the Yellow Sea Fisheries Research Institute in Qindao, People’s Republic of China and organised by the Regional Seafarming Development and Demonstration Project in May 1991.
