Potential and prospects of southeast Asian eel resources for sustainable fisheries and aquaculture development The world demand for river eels has been increasing mainly because of the market expansion of some delicacies such as the kabayaki (broiled eel with sweet soy sauce) in East Asia. While most of the world’s eel production is derived from aquaculture, it should be noted that eel aquaculture is still dependent on the natural resources. As techniques for the full-life cycle aquaculture of eels have not yet been fully developed for commercial use, the eel aquaculture industry is still solely dependent on wild resources for seed stocks. However, the natural resources had been confronted with various factors that could possibly create negative impacts on the eel resources including habitat alteration, overexploitation, climate change, pollution, and incidence of diseases. Thus, concerns on the sustainability of various eel species in the world have increased in recent years. It should be reckoned that the European and American eels are already threatened to certain degree by pollution and damming (or the construction of dams that prevent their migration to freshwater bodies) leading to almost “close to collapse” of the European eel resources. This situation prompted CITES to list the European eel (Anguilla anguilla) in CITES Appendix II in 2009 and accordingly, trade restrictions of the European eel and its products came into effect. In Southeast Asia, it is known that aquaculture and inland capture fisheries of eel are practiced but data and information on the total production of eel in the region remain very minimal. In this regard, the Southeast Asian countries have been encouraged to report their respective eel production to SEAFDEC in order that the status and trend of the region’s eel resources could be established and the statistics could be appropriately reflected in the Fishery Statistical Bulletin of Southeast Asia produced yearly by SEAFDEC. Meanwhile, in an effort to conserve the eel resources in Southeast Asia, SEAFDEC recently launched a project on Conservation, Management and Sustainable Utilization of Eel Resources in Southeast Asia with funding support from the Trust Fund for SEAFDEC of the Fisheries Agency of Japan.
BookLMB Garcia (Ed.) - 2001 - SEAFDEC Aquaculture DepartmentThis report describes the present state of marine resources in several coastal barangays of Ibajay and Tangalan, Aklan (Philippines). Field data were obtained from rapid surveys conducted from July to September 1998. Recommendations based on analyses of the data will guide fisherfolk and other stakeholders, particularly the local government units, in their development plans for these neighboring municipalities. Both land and marine products in the area are mainly harvested for the local market. All coastal barangays are dependent on fishing for their livelihood. The medium-scale municipal fishery of Tangalan employs several passive (encircling gill net, bag net, fish corral) and active gears (baby purse seine) compared with the traditional fishing methods employed by Ibajay fishers. Pond aquaculture in mangrove areas is well-developed in Ibajay West (barangays Aquino and Ondoy) and in Tangalan. However, ownership of these ponds is limited to a few individuals and families, unlike in Barangay Bugtong Bato where informal ownership distributed among families has been the traditional rule. Nonetheless, the introduction of so-called environment-friendly methods of utilizing mangroves (e.g., aquasilviculture) and other shared coastal resources may seriously undermine the informal rights-based social structures in the barangays. Without proper rules and enforcement, the application of these methods may be misused, aggravating the already poor overall state of their coastal resources. Major problems affecting their fishing livelihood include siltation of nearshore waters due to illegal deforestation upland, encroachment of municipal fishing grounds by commercial and other fishers elsewhere, and the lack of capital to finance the fishery. Weak inter-organizational links among government and non-government organizations have hampered the implementation of solutions to these common problems in coastal barangays. For instance, a conflict between fishers from these neighboring municipalities over territorial boundaries of common fishing grounds in Pangayawan and Pungtod reefs has not been resolved over the years. Likewise, the introduction of aquasilviculture in mangrove areas may become a potent source of conflict among resource-users who maintain informal rights over the mangrove resource. The overall state of coastal resources in these municipalities is in immediate need of a unified plan to promote both their preservation and conservation. To achieve this end, a joint resource management council representing all resource-users from both municipalities must be organized and convened. To address the presently weak inter-organizational links among existing organizations, this joint council may provide a legitimate forum to identify, resolve, integrate, implement, and enforce guidelines on the common use of resources, both marine and inland. Low estimated yields from the reef fishery, conversion of mangroves for aquaculture beyond the allowable limit, a persistent conflict over fishing rights in several reefs offshore, the limited resources for seaweed and fish mariculture, and threats on existing traditional social structures by progressive resource-users are several issues that require thorough discussions to formulate popularly approved and acceptable management strategies. These strategies include community-based approaches of co-managing resources such as "no-take zones" (sanctuaries), ecotourism development, and livelihood schemes to mitigate, in part, the pressure of over-exploitation of fishery resources.
Conference paperH Thein - 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 CenterMyanmar has impressive freshwater capture fisheries. Inland freshwater bodies cover 8.1 million ha of which 1.3 million ha are permanent while the rest are seasonally inundated floodplains. There are repeated references to the crucial importance of fish and fish products in the nutrition of the Myanmar people. Over the past few decades, inland fisheries resources have increased pressure from overfishing, use of destructive fishing gear/methods, pollution and environment changes. In order to make a sustainable inland capture fisheries and conservation of aquatic biodiversity as well as nutritional security and improved rural livelihoods, fisheries resource enhancement and conservation measures have long been adopted in Myanmar since 1967, initiated through a seed replenishment program in natural waters, such rivers, lake, dams, even rice fields, etc. However, the institutional, policy, legislative and financial environments under which enhancement and capture fisheries regimes exist are not conducive to the interests of the fishers. Strong tools for valuation of ecosystem goods and services, enabling governance arrangements and estimation of environmental flows are needed. Fishing communities need to be organized into strong co-management/participatory/community regimes in order to ensure that all stakeholders take part in decision-making process and the benefits accrued are shared equitably by all.
