Sustaining environmental integrity in the midst of intensified aquaculture development
MetadataShow full item record
The escalating aquaculture production from Southeast Asia during the past decades seems inevitable notwithstanding its significant contribution to economic growth and guaranteed food security of the countries in the region. Despite its good prospects, the region’s aquaculture sector is being confronted with various issues that should be addressed to enable it to develop sustainably and contribute unceasingly to poverty alleviation in the region. Responsible aquaculture has been practiced in the region as means of easing the crisis in capture fisheries; however, this has to be matched with effective approaches that address concerns on the fishery resources that are deteriorating. Resource enhancement of economically important aquatic species has been considered as one of the effective approaches that would help protect and restore the aquatic resource habitats and stocks, the latter connotes stock enhancement. As could be gleaned from the current scenario of fisheries in the Southeast Asian region, the recurring over-exploitation of common natural resources has affected the livelihoods of fishers and coastal communities. The imbalanced extraction of natural aquatic resources and natural recruitment has worsened through the years and if left unabated could result in the extinction of many of the region’s endemic aquatic species. It is for such consequences that the Aquaculture Department of the Southeast Asian Fisheries Development Center, while intensifying its efforts in developing sustainable aquaculture, is also promoting resource enhancement as these two approaches are expected to enhance the region’s fishery resources and food security in view of their perfect roles in improving the productivity of aquatic stocks and status of the natural habitats. Nonetheless, aquaculture techniques have always been used to facilitate the stock enhancement of commercially important, threatened and endangered aquatic species. The National Oceanic and Atmospheric Administration of the USA defines stock enhancement as “restoration aquaculture” or the release of hatchery-bred juveniles of fish and shellfish to the wild, and considers this approach as a management tool to recover depleted stocks due to overfishing and habitat loss. The Food and Agriculture Organization of the United Nations has demonstrated that stock enhancement is a type of culture based fisheries since part of the life cycle of certain aquatic species is being controlled in hatcheries before the seeds or juveniles are transplanted or released into open waters — freshwater or brackishwater or marine environments — and allowed to propagate or grow on natural foods until reaching harvestable size.

Institutional capacity development for sustainable aquaculture and fisheries: Strategic partnership with local institutions RF Agbayani & JD Toledo - In K Tsukamoto, T Kawamura, T Takeuchi, TD Beard Jr. & MJ Kaiser (Eds.), Fisheries for Global Welfare and Environment: Memorial Book of the 5th World Fisheries Congress 2008, 2008 - TerrapubMany people living in the rural areas in the Philippines, as in other developing countries in Southeast Asia, depend on aquatic resources for their food and livelihood. For the past two decades, the Aquaculture Department of the Southeast Asian Fisheries Development Center (SEAFDEC-AQD) has been working with fishing communities and people’s organizations, business sector, local government units, national government agencies, non-government organizations (NGOs) and academic and other research institutions to promote the efficient conservation, management and sustainable development of the country’s fisheries and aquatic resources so that these may continue to serve the needs of the people today and tomorrow. Using the lessons learned from those two decades of multi-sectoral and inter-disciplinary collaborations, SEAFDEC-AQD launched in late 2006 a project called Institutional Capacity Development for Sustainable Aquaculture (ICDSA) to hasten the transfer to and adoption by coastal villagers of appropriate technologies that would enhance the productivity of aquatic resources and at the same time safeguard the fragile balance of the aquatic ecology. The experience of SEAFDEC in coastal resource management shows that it is important to engage the collaboration of the local government units and other “on-the-ground” institutions, such as NGOs and people’s organizations, to be able to introduce effectively any social and technological interventions to target community-beneficiaries. However, before a fruitful collaboration among these institutions could be attained, there is a need to build their capacities, and those of the beneficiaries, for the vital roles that they play in the implementation of livelihood projects and environmental management programs. As of January 2008, SEAFDEC-AQD is implementing ICDSA projects in four provinces—Antique, Capiz, Guimaras and Northern Samar in central Philippines. In the pipeline are similar projects for a province in southern Philippines and two provinces in the north.
Conference paperH Choudara - In JH Primavera, ET Quinitio & MR Eguia (Eds.), Proceedings of the Regional Technical Consultation on Stock Enhancement for Threatened Species of International Concern, Iloilo City, Philippines, 13-15 July 2005, 2006 - Aquaculture Department, Southeast Asian Fisheries Development CenterFisheries development in Lao PDR is confined to inland fisheries development and sustainable freshwater aquaculture including culture-enhanced capture fisheries and fishery-enhanced aquaculture. Given the potential of water, wetland and aquatic resources and the magnitude of decline in fish catches from the Mekong River and its tributaries, the Government of Lao PDR has given priority to fisheries development with strong concern for sustainable aquaculture. The overall policy framework is therefore geared toward the sustainable use, appropriate management and protection of natural resources: forest, land and water resource including aquatic biodiversity. The national goal for fisheries development during the last decade was focused on how to increase fish production from aquaculture while maintaining capture fisheries, recognizing that about 50% of the dietary protein of Lao people comes from living aquatic resources which are important for food security of the nation.
Conference paperAS Camacho & N Macalincag-Lagua - In JV Juario & LV Benitez (Eds.), Seminar on Aquaculture Development in Southeast Asia, 8-12 September 1987, Iloilo City, Philippines, 1988 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe aquaculture sector of the Philippine fishing industry registered the highest growth rate of 12.5% in 1977-1986. The contribution of aquaculture to the total fish production was equivalent to 24% in 1986 compared to only 85 in the early 1970's. In terms of quantity, the mariculture subsector registered the highest growth rate of 10.2% in 1982-1986, whereas in terms of value the brackishwater fishpond subsector showed the highest growth rate of 33%. Meanwhile, freshwater aquaculture production exhibited a negative growth rate due to reduction of activities in Laguna de Bay and the slow expansion in hectarage of the commercial freshwater fishponds. Research by several agencies concentrated heavily on the culture of milkfish (Chanos chanos), tilapia (Oreochromis niloticus), Chinese carps (Aristichthys nobilis and Hypophthalmichthys molitrix), tiger prawn (Penaeus monodon), and sea bass (Lates calcarifer). Innovations in seaweed, oyster, and mussel farming are also discussed. Research directions are presented to assure an ecologically sustainable growth in aquaculture with emphasis on countryside development.
