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.

Culture-based fisheries (CBF) are practices to enhance fish stocks in waters that don't have enough natural recruitment to sustain a fishery. CBF practices are usually applied in small water bodies such as village dams and irrigation reservoirs. Fish growth is driven by the natural productivity of the waters. Usually there is no feeding and the fish are left to forage on natural food supplies. Ownership and management of the stock distinguish CBF as form of extensive aquaculture.

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 publishes technical papers and manuals for a wide variety of farming systems and related environmental and social issues. Many of these provide guidance on better management practices with a view to improving crop outcomes and on-farm resource utilisation efficiency. By using inputs such as feed and power more efficiently, farmers can simultaneously improve their profitability and environmental performance.

The Quarterly Aquatic Animal Disease report provides information about the status of aquatic animal disease in 21 participating states in the Asia-Pacific region. The diseases covered in the report are reviewed annually by the Asia Regional Advisory Group on Aquatic Animal Health. The report was first published in the second quarter of 1998. It is a joint activity between NACA, FAO and the OIE Regional Representation (Tokyo). 

Ths paper enumerates different carp integrated farming systems being prevalent in Asia along with successful case studies indicating potential and constraints of such systems. It recommends to integrate carp farming with agriculture and irrigation, livestock farming, sewage utilisation and water pollution control not only to increase the productivity of land and water and improve the economic conditions of poor farmers but also to maintain health and hygiene of the rural poor and city dwellers alike.

This document briefly describes the status of the aquaculture in the Regional Aquaculture Lead Centre for Thailand circa 1981, in terms of available species and research priorities. Work was conducted on air-breathing catfish Clarias batrachus, snakehead Channa striatus, giant freshwater prawn Macrobrachium rosenbergii, silver barb Puntius gonionotus, snakeskin gourami Trichogaster pectoralis, mussels Perna viridis and oysters Crassostrea spp. Includes brief descriptions of culture methods prevalent for these species at the time.
