Economics of aquaculture feeding practices in selected Asian countries. FAO Fisheries Technical Paper No. 505, edited by Mohammad R. Hasan, 205p.
This technical paper provides an analysis of the economic implications of, and the reasons for, adopting various feeding practices for different fish species and aquaculture systems in Asia. It consists of case studies in six Asian countries (Bangladesh, China, India, the Philippines, Thailand and Viet Nam) and an overall synthesis ending with conclusions and recommendations. The systems studied include extensive/traditional, semi-intensive and intensive farms for a number of different species including sutchi and pangasiid catfishes (Bangladesh and Viet Nam), hybrid catfish (Thailand), carp polyculture (India and China), prawn and milkfish polyculture (the Philippines). The work identifies the principal input costs, assesses the economic rates of return (gross and net margins), returns to labour, land and capital, gross and net total factor productivity, and break-even prices and production. For the most part, intensive farms applying industrial feeds attained the highest economic returns, although not necessarily the highest benefits. |

Study and Analysis of Feeds and Fertilizers for Sustainable Aquaculture Development, FAO Fisheries Technical Paper 497, Edited By Mohammad R. Hasan, Thomas Hecht, Sena S. De Silva, Albert G.J. Tacon, 2007, 507 pp.
NACA is pleased to post the above FAO publication which has brought together a voluminous amount of information on global practices on feeds and fertilizer usage in aquaculture. This volume is the result of a workshop that was held in Wuxi, PR China that brought together 21 experts from different regions to reflect the diversity of aquaculture practices and the feeds and fertilizer usage in those practices. The book provides information on the use of feeds and fertilizers in individual countries (nine from Asia and Six from Africa) that is not readily available to most, and also includes a global synthesis and three regional reviews (Africa, Asia and Latin America) on feeds and nutrients for sustainable aquaculture. It also contains a workshop report that deals with recommendations for sustaining aquaculture development in the above regions. |

By M.G. Hussain, Bangladesh Fisheries Research Institute.
ISBN 984-32-1839-6, hardcover, 149 pages.
Tilapia has recently been recognized as a global fish and described as one of the most important aquaculture species of the 21st century. Farming practices of the fish from extensive to super-intensive both for fresh and brackish waters are expanding day by day in Asia and many countries of the world. It has been felt that very little readily available information on farming practices of tilapia is available in Bangladesh and elsewhere in the region. Therefore, this comprehensive handbook has been published for national and international readers.
The book consists of 12 chapters covering mainly tilapia biology, brood stock replacement and breeding plans, simple genetics, development and operation of mixed and monosex commercial seed production systems including semi-intensive and intensive culture systems, disease and parasite control, marketing and future strategies and prospects of frontiers development of tilapia aquaculture.
It is expected that this book will be useful as a guide to hatchery operators, entrepreneurs, progressive farmers, researchers and planners developing programs for simple breeding, stock improvement, mass seed production and various aquaculture techniques of the fish in Bangladesh and elsewhere in Asia where tilapia is being used for promotion of aquaculture. |

 The first planning meeting for the iceida-funded project Strategies for Development of Asian Reservoir and Lake Fisheries Management and Development was held 14-16 January in Bangkok. The main objective of the meeting was to identify priority activities and develop a work plan for the two-year project. Based on the deliberations, ten projects have been selected considering the importance of each to the proposing country as well as its degree of relevance to reservoir fisheries management and development in the region.
NACA is pleased to announce that the activities selected for funding are:
- Role of fish species introduction in reservoir fisheries in China. A case study on successful introduction of icefish in Chinese reservoirs. Implemented over two years by the Institute of Hydrobiology and the Freshwater Fisheries Research Centre, Chinese Academy of Fisheries Sciences.
- Investigation of successful practices of culture-based reservoir fisheries in China. Implemented over two years by the Freshwater Fisheries Research Centre and the Institute of Hydrobiology, Chinese Academy of Fisheries Sciences.
- Capacity building of field staff on scientific aspects of inland fisheries development and effective data collection methods. Implemented over 6 months by the National Aquaculture Development Authority of Sri Lanka and Aquatic Resources and Quality Improvement Project.
- Exploitation of untapped fishery resources in reservoirs through proper management. Implemented over two years by the University of Kelaniya, the National Aquaculture Development Authority of Sri Lanka and the National Aquatic Resources Research & Development Agency.
- Impact of stocking size of fingerlings on culture-based fisheries in village reservoirs and their implications on the economics of mini-nurseries. Implemented over two years by the National Aquaculture Development Authority of Sri Lanka and National Aquatic Resources Research & Development Agency.
- Strengthening and consolidation of the knowledge of reservoir and lake fisheries management for livelihood improvement of near by communities. This will have two components implemented over a total of two years the Nepal Agricultural Research Council and Directorate for Fisheries: i) complete documentation of the success story of provision of alternative livelihoods to displaced communities at Indrasarrobar Reservoir, Kulekhani, and ii) Updating the database/profile on reservoirs and lakes (tectonic and oxbow) in respective to fisheries development and conservation management, specifically Jagdishpur Reservoir, and the Pokhara and Rupa lakes, Kapilvastu.
- Trend analysis of reservoir fisheries in Thailand. Implemented over 18 months by the University of Udornrachathani.
- Evaluation of the contribution and performance of tilapia and Macrobrachium rosenbergii to the fisheries in selected reservoirs in Thailand. Implemented over 18 months by the University of Udornrachathani.
- An evaluation and critique of tilapia fisheries outside Africa. Implemented over 18 months by NACA; the University of Kelaniya, Sri Lanka; the Department of Fisheries, Thailand, and the University of Udornrachathani, Thailand.
