Community-based shrimp stock enhancement for coastal socio-ecological restoration in the Philippines J Altamirano, H Kurokura, ND Salayo, D Baticados, JG Suyo & S Ishikawa - In MRR Romana-Eguia, FD Parado-Estepa, ND Salayo & MJH Lebata-Ramos (Eds.), Resource Enhancement and Sustainable Aquaculture Practices in Southeast Asia: Challenges in Responsible Production … International Workshop on Resource Enhancement and Sustainable Aquaculture Practices in Southeast Asia 2014 (RESA), 2015 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe reality of declining quality of coastal areas has been evident for many developing countries, especially in Southeast Asia. In the Philippines, rural coastal zones and estuaries are now being characterized by declining wild fisheries resources and degrading environment. This paper presents, as an example, the typical rural coastal towns of New Washington and Batan in Aklan province, Philippines and showcases how the concept of shrimp stock enhancement can provide incentives to restore the environment and provide sustainable fishing livelihood in the area.The New Washington-Batan Estuary in northeast Panay Island, Philippines was a productive fishing ground that has been in a state of degenerating brackishwater fisheries and estuarine environment. Average daily catch composed of various species decreased from 24 kg in 1970s to 0.7 kg at present. Shrimp fisheries, the most important livelihood, declined in quality and quantity. The highly-priced and once very abundant tiger shrimp Penaeus monodon was replaced with smaller-sized and lower-priced species like the Metapenaeus ensis. These can be attributed to the conversion of 76% of mangroves to culture ponds in the past 50 years and more than 400% increase in fishing gears since the 1990s. The need to reduce fishing structures and rehabilitate mangroves is evident. However, these drastic changes directly affect fishers livelihood. This paper explores the prospects of P. monodon stock enhancement as positive reinforcement for the estuary s rehabilitation. Number of gears per fisher may have to be reduced but shrimp catches will be relatively high-priced. Simulations with additional tiger shrimp caught due to stock enhancement show that fishers can increase income by more than 4 times from their current PhP 34 gear-1 day-1. Campaigns on the importance of mangrove especially as shrimp habitat can encourage local communities to reforest the estuary especially in abandoned ponds. With effective management, law enforcement, and sustained support from different sectors, shrimp stock enhancement can be a positive strategy in estuarine rehabilitation and livelihood sustainability in the New Washington-Batan Estuary.
Conference paperRF Agbayani - In TU Bagarinao & EEC Flores (Eds.), Towards sustainable aquaculture in Southeast Asia and Japan: Proceedings of the Seminar-Workshop on Aquaculture Development in Southeast Asia, Iloilo City, Philippines, 26-28 July, 1994, 1995 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe Community Fishery Resources Management Project, launched in 1991 in Malalison Island, Philippines is a development-oriented research project integrating biology, economics, sociology, engineering, and public administration. The general objective is to support, and learn from, the collaboration of people's organization, biologists, and social scientists in applying community-based techniques in fishery management. During Phase I, the Project concentrated on community organizing, institution building, and the introduction of seaweed farming as alternative livelihood. Studies were made on the marine resources of the island, the traditional boundaries and territorial use rights, the economic utilization of resources in the island, and the cultivation techniques for seaweeds. Phase II started in 1994 with the implementation of the territorial use rights in fisheries and the test deployment of prototype concrete artificial reefs. Phase II includes impact assessment (environmental, social, and economic), institutional arrangements in fishery co-management, ethnographic studies, economics of Seafarming techniques, and management of fishery cooperatives.
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.
