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.

This report documents a training course that was held at the Research Institute for Mariculture, Bali, Indonesia in May 2003. The course covered both theoretical aspects of grouper husbandry via lectures and practical hands-on work in a grouper hatchery, including broodstock management, tank preparation egg collection, live feed production, health management, harvesting and transport and visits to commmercial grouper and milkfish hatcheries, grow-out facilities, markets and exporters.

The Asia-Pacific Grouper Network was initiated in 1998 at a meeting of grouper aquaculture researchers in Bangkok, Thailand, to promote effective regional cooperation among Asia-Pacific economies involved in grouper aquaculture research and development. This report has been prepared based on the recommendations of the NACA member governments to formalise the network within NACA as a regional network to support research and development in marine fish culture in the Asia-Pacific region.

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.
