These are the proceedings of a workshop hosted by APEC and NACA under the project 'Collaborative APEC-NACA Grouper Aquaculture Network' (APEC Project FWG 01/99). The objectives of the workshop included the establishment of a regional research network to facilitate development of a sustainable grouper aquaculture industry; reduction of reliance on wild fingerlings for coastal grouper aquaculture, facilitate development of new aquaculture industries.

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.

The Asia Regional Advisory Group on Aquatic Animal Health meets annually to discuss regional disease issues including emerging disease threats. The group was established by the Governing Council of NACA to provide advice to member governments in the Asia-Pacific region. This collection comprises the reports of the annual meetings of the group. The reports are a rich source of information concerning the current disease status of the region and new or emerging diseases of aquatic animals.

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.
