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.

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 frequently organises technical workshops and consultations on aspects of aquaculture. The proceedings of such meetings are made available for free download. Audio and video recordings of technical presentations are also available for some meetings (please see the podcast section).

Information about the NACA Secretariat and key documents.

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.
