The sixteen papers in this volume were largely based on the data from a survey of more than 5,000 shrimp and close to 6,000 carp farms in sixteen countries and territories in the Asia-Pacific region. They provide an economic and technical efficiency of production analysis for Asian shrimp and carp farming systems. This survey was conducted under the ADB/NACA regional study and workshop on aquaculture sustainability and the environment (RETA 5534).

The Kathmandu symposium on coldwater fishes made recommendations covering three major themes: (1) distribution and conservation of coldwater fishes; (2) role of coldwater fishes in rural development and poverty alleviation; and (3) coldwater fisheries and aquaculture development. This report presents the  the recommendations of the three working groups. The symposium recommended regional cooperation among countries of the Trans-Himalayan region be strengthened for effective sharing and exchange of skills, experiences and technical cooperation.

This volume is the proceedings of the Symposium on Cold Water Fishes of the Trans-Himalayan Region, held in July 2001 in Kathmandu, Nepal. In 32 presentations it reviewed information, experiences, ideas and findings related to fish and fisheries in the region, including fish species distribution, fishing intensity, socio-economic conditions and livelihoods of fisher communities, as well as to the impact of environment degradation, conservation measures and aquaculture technologies for indigenous and exotic cold water fish.

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.
