Aquaculture for diversification of small farms within forest buffer zone management: an example from the uplands of Quirino Province, Philippines.
(2002)Type: Book ChapterUpland farming systems can have severe negative effects through intensified slash-and-burn activities, erosion-enhancing farm practices on moderate to steep slopes, and further encroachment into forest areas. ICLARM studied, ... -
Aquaculture potential of seahorses and pipefishes
(1995)Type: Journal ArticleThe characteristics, food and feeding, reproduction and breeding of sea horse and pipefishes (Synanthidae) are presented together with the aspects of syngnathid culture. -
Community based fish culture in seasonally flooded rice fields in Bangladesh and Vietnam
(2004)Type: Conference ProceedingsDuring the rainy season in extensive river floodplains and deltaic lowlands, floods lasting several months render the land unavailable for crop production. These waters are considerably underutilized in terms of managed ... -
Community-Based Fish Culture in Seasonal Floodplains
(2006)Type: Journal ArticleDuring the rainy season in extensive river floodplains and deltaic lowlands, floods render the land unavailable for crop production for several months each year. These waters are considerably underutilized in terms of ... -

Delineating recommendation domains for small-scale freshwater aquaculture: deploying GIS for decision support
(2007)Type: Book ChapterThis paper highlights Geographical Information System (GIS) applications in an on-going, three-year project to develop spatial decision-support tools for identifying recommendation domains (places and sets of conditions) ... -
Economic feasibility of community based fish culture in seasonally flooded rice fields in Bangladesh and Vietnam - Community Based Fish Culture in Seasonal Floodplains
(2005)Type: Journal ArticleDuring the rainy season in extensive river floodplains and deltaic lowlands, floods lasting several months render the land unavailable for crop production for several months each year. These waters are considerably ... -
Evolution of shrimp aquaculture systems in the coastal zones of Bangladesh and Vietnam: a comparison
(2010)Type: Book ChapterBased on on-farm surveys implemented in the Ganges Delta in Bangladesh and the Mekong Delta in Vietnam, the dynamics of shrimp aquaculture in salinity-influenced coastal areas were analysed. Qualitative data were collected ... -
Ex-ante impact assessment for research on natural resources management: methods and application to aquatic resource systems
(2005)Type: Journal ArticleUnder a particular representation of the impact path way of natural resource management (NRM) research, economic surplus techniques can also be used for ex ante impact assessment. The method is applied to the case of the ... -
Farmer-participatory research approaches towards agriculture-aquaculture integration for sustainable management of natural resources
(1996)Type: ReportThe direct and indirect effects of recycling can have significant impacts on the ecological sustainabilty of the entire farming system. Indirect effects include the integration of new enterprises that promote recycling as ... -
Fitting growth with the von Bertalanffy growth function : a comparison of three approaches of multivariate analysis of fish growth in aquaculture experiments
(2005)Type: Journal ArticleThree approaches for multivariate analysis of fish growth in aquaculture experiments with Nile tilapia (Oreochromis niloticus niloticus L.) based on the von Bertalan¡y growth curve are presented and compared. The approaches ... -
Impact of development and dissemination of Integrated Aquaculture-Agriculture (IAA) Technologies in Malawi
(2006)Type: Journal ArticleMalawi is a small but densely populated country in Southern Africa. Fish is an important part of the nutrition of Malawians, providing essential protein and micronutrients. However, per capita fish consumption has halved ... -
Impact pathway analysis for research planning: the case of aquatic resources research in the WorldFish Center
(2004)Type: Journal ArticleIn line with its mandate of poverty reduction and sustainable development, the WorldFish Center is orienting its research towards high impact scientific activity. Identifying such activities is the task of prospective ... -
Increased Income from Seasonally Flooded Rice Fields through Community Based Fish Culture in Bangladesh and Vietnam
(2005)Type: Journal ArticleIn extensive river floodplains and deltaic lowlands, floods lasting several months render the land unavailable for crop (often rice) production during the rainy season. Aside from crop production during the flood-free dry ... -
Integrated smallholder agriculture aquaculture in Asia: optimizing trophic flows
(1999)Type: Book ChapterA nutrient modelling approach was applied to show how the combination of crops, trees, livestock, and fish, that is, integrated agriculture-aquaculture (IAA), helps in optimizing trophic flows in Asian rice-based agroecosystems. ... -
Integrating agriculture, fisheries and ecosystem conservation: Win-win solutions
(2006)Type: Journal ArticleIntegrated Agriculture-Aquaculture (IAA) is essentially diversification of agriculture, leading to synergisms among sub-systems resulting in a higher productivity from land/water area under the farmers' control. One method ... -
Integration of aquaculture into crop-animal systems in Asia
(2002)Type: Journal ArticleThe status of integrated agriculture-aquaculture (IAA) in Asia is reviewed, with an emphasis on rural small-scale systems. Existing IAA systems within mixed farming systems are characterised and the economic and ecological ... -
