This book is the proceedings of the “Regional Consultation on Culture-Based Fisheries Development in Asia”, held in Siem Reap, Cambodia, 21-23rd of October 2014, under the auspices of the Australian Centre for International Agricultural Research (ACIAR), the Mekong River Commission (MRC) and the Network of Aquaculture Centres in Asia-Pacific (NACA). The consultation was jointly organised by NACA and the Fisheries Administration of the Royal Government of Cambodia.

Food and nutritional security remains problematic in many developing countries.  There are many initiatives underway which are designed to increase food supply, employment and income opportunities, most of which require considerable capital inputs (for instance cropping, livestock production and aquaculture). Often overlooked, are the opportunities to produce more food from the natural productive ecology of lakes and forests. Culture-based fisheries are one example of a relatively simple and low cost technology which can deliver nutritional and economic benefits to communities which often have few livelihood options.

Culture-based fisheries are based in lakes and reservoirs, where fish populations are supplemented by hatchery-produced fingerlings. The stocked fish may breed naturally in the lakes, or they may be species which are desirable but which do not breed in the still-water environments. Fish growth is driven by the natural productivity of the water bodies. Generally, local communities have ownership of the fish, with the benefits shared or used for communal purposes. However, there are other options for management and ownership depending on local needs, cultural arrangements and other uses of the water.

Research and development of culture-based fisheries has been a major endeavour for NACA and ACIAR since the mid-1990s. This has involved projects in Sri Lanka, Indonesia, Vietnam, Lao PDR and Cambodia, the results of which have been reported in previous publications, as noted below. In this volume, we bring together an update from research conducted in those countries and others. We trust the information will foster further development and spread of culture-based fisheries in Asia and beyond, and in doing so, bring livelihood and nutritional benefits to otherwise resource-poor communities.

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.

Results of a decade of R&D efforts on culture-based fisheries in Sri Lanka

12 May 2015 | U. Amarasinghe, U. and W.M.H.K. Wijenayake | 1964 Downloads | .pdf | 1.72 MB

Culture-based fisheries in village reservoirs of Sri Lanka is a communal activity involving agricultural farmers without prior experience in fisheries. Awareness programs have facilitated establishment of CBF in small village reservoirs. Dissemination of research findings through means such as production of a documentary film, publication of a monograph which was translated to several regional languages, and holding a series of regional workshops were instrumental for CBF development at the regional level.

Potential of culture-based fisheries in Indonesian inland waters

Fish stocking in Indonesian lakes and reservoirs has been conducted for a long time. Since 1999, culture-based fisheries (CBF) practices based on scientific evidence such as using suitable fish species, consideration of the primary productivity, stocking density, economic evaluation and community participation, have been conducted in some reservoirs and lakes and have showed encouraging results. CBF is highly recommended and prioritised in small reservoirs with an area less than 200 ha.

Impact of introduction of culture-based fisheries on fish production in perennial reservoirs of Sri Lanka

12 May 2015 | J. Chandrasoma, K.B.C. Pushpalatha and W.A.J.R. Fernando | 2558 Downloads | .pdf | 453.97 KB

Sri Lanka is blessed with a large number of irrigation reservoirs. Culture-based fisheries (CBF) in seasonal reservoirs was initiated in the 1980’s and the government has recognised CBF as an effective way of increasing fish supplies in rural areas, at affordable prices, while providing employment and income to farmers and thereby contributing towards alleviation of poverty. The role of fisher community based organisations and fisheries management for effecting successful CBF are discussed.

Culture-based fishery of giant freshwater prawn: Experiences from Thailand

12 May 2015 | T. Jutagate and W. Kwangkhang | 5528 Downloads | .pdf | 429.01 KB

Releasing of giant freshwater prawn (Macrobrachium rosenbergii) for the purposes of stock enhancement and to create a fishery has been conducted in Thailand since the 1980s. Average age at harvest is around 6 to 8 months, with an average total length of 20 cm. Overall, the success of stocking M. rosenbergii is poor since the recapture rate is generally less than 5 %. However, the economic return is high.

Culture-based fisheries in lakes of the Yangtze River basin, China, with special reference to stocking of mandarin fish and Chinese mitten crab

In this paper, the culture-based fisheries in lakes are presented, with special reference to mandarin fish and mitten crab stocking in lakes in China. The stocking rate of mandarin fish is determined by food consumption rates, which are mainly related to water temperature and fish size, and prey fish productivity. A bioenergetics model of mandarin fish was established to predict the growth and consumption of prey fish in stocked lakes.

Coastal water quality monitoring in shrimp farming areas: An example from Honduras

31 May 2005 | Claude E. Boyd and Bartholomew W. Green | 5087 Downloads | .pdf | 404.31 KB

Various substances in shrimp farm ponds can contaminate waters, including nutrients, metabolic wastes, veterinary chemicals, and suspended soil particles from erosion. This report discusses ways to monitor these aspects of water quality, which is important from two standpoints for shrimp farmers. Incoming water used top supply shrimp ponds must be healthful and free of toxins to protect the growing shrimp, and effluent must be clean enough to avoid harming aquatic ecosystems and water quality standards downstream.
