      The economics of the milkfish fry and fingerling industry of the Philippines 

      IR Smith - 1981 - International Center for Living Aquatic Resources Management; Aquaculture Department, Southeast Asian Fisheries Development Center
      Series: ICLARM technical reports; 1
      The fry and fingerling industry of the milkfish (Chanos chanos Forskal) in the Philippines is alleged to suffer from certain imperfections. Primary among these are an annual shortage of catch necessary to meet the stocking requirements of the 176,000 ha of fishponds; high fry mortality rates during transp0rt;failure of the pricing system to perform its spatial and form allocative functions; and exploitation of fry gatherers and pond operators by middlemen and nursery pond operators who form the core around which the whole fry and fingerling industry has developed. These alleged imperfections provide the rationale for various government policies affecting the fry and fingerling industry.

      This study indicates a higher level of industry performance than hitherto supposed. In 1974, an estimated 1.35 billion fry were caught, adequate to meet annual stocking requirements. Allegations of fry shortage were based on simultaneous underestimation of catch and overestimation of stocking requirements, and were traced to temporary price increases resulting from expanded fishpen area, which subsequently declined. Fry storage and transport mortality rates of 8.7% and 6.6%, respectively, compared with a mortality rate of 54% during rearing, indicated that major technical inefficiencies arise in fishponds rather than in the distribution system. Of every 100 fry caught, 38 are harvested at marketable size.

      Monthly average fry prices among 17 major trading regions were significantly correlated, indicating a high level of information flow in the industry. An examination of the concession system which restricts first sale opportunities of gatherers indicated that concessionaires are unable to capture their full monopsony advantage due to the "competitive fringe" of smugglers. Rather than exploitation, the concession system is a form of indirect municipal tax on fry gatherers.

      Since the fry industry is a 57-million-peso-per-year industry upon which approximately 170,000 people directly and indirectly depend, it is suggested that the location of future milkfish hatcheries and timing of production be planned such that they complement rather than displace the natural fry fishery and distribution system.

      Use of Chemicals in Aquaculture in Asia : Proceedings of the Meeting on the Use of Chemicals in Aquaculture in Asia. 

      JR Arthur, CR Lavilla-Pitogo & RP Subasinghe (Eds.) - 2000 - Aquaculture Department, Southeast Asian Fisheries Development Center
      The use of chemicals is common in various aquaculture systems, as it is in many agricultural practices. However, with growing worldwide awareness of the need for responsible practices in aquaculture, governments and aquaculturists are increasingly concerned with the effects of the use of chemicals in aquaculture, especially those which appear likely to be hazardous to man, cultured stock and/or the environment. The need to synthesize and disseminate information on the use and management of double prime aquachemicals double prime was recognized by the Fishery Resources Division of the Food and Agriculture Organization of the United Nations (FAO) and the Southeast Asian Fisheries Development Center (SEAFDEC) Aquaculture Department, who convened double prime The Expert Meeting on the Use of Chemicals in Aquaculture in Asia, double prime which was held 20-22 May 1996 at the SEAFDEC facilities in Tigbauan, Iloilo, the Philippines. Support was provided by FAO, SEAFDEC and the Canadian International Development Agency s (CIDA) ASEAN Fund. The World Health Organization (WHO) supported the participation of a human health expert. The meeting was attended by 27 participants and more than 70 observers from the public and private sectors of 20 countries. Among the attendees were representatives from the Network of Aquaculture Centres in Asia-Pacific (NACA), the Fish Health Section of the Asian Fisheries Society (FHS/AFS), the Japan International Research Center for Agricultural Sciences (JIRCAS), the GESAMP Working Group on Environmental Impacts of Coastal Aquaculture, and the ICES Working Group on Environmental Interactions of Mariculture. The results of this expert workshop are presented in this volume. They include the texts of presentations on a wide range of topics (thematic reviews) related to the use of chemicals in aquaculture, with emphasis on the Asian Region, as well as country overview papers summarizing the use of aquachemicals in Asian countries. The contributions of the selected participants during the meeting are contained in this volume.

      An assessment of the coastal resources of Ibajay and Tangalan, Aklan: Implications for management 

      LMB Garcia (Ed.) - 2001 - Aquaculture Department, Southeast Asian Fisheries Development Center
      This 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.

      Proceedings of the National Seaweed Planning Workshop held on August 2-3, 2001, SEAFDEC Aquaculture Department, Tigbauan, Iloilo. 

      AQ Hurtado, NG Guanzon Jr., TR de Castro-Mallare & MRJ Luhan (Eds.) - 2002 - Aquaculture Department, Southeast Asian Fisheries Development Center
      Seaweed forming is one of the major livelihoods among coastal communities in the Philippines, particularly to some 180,000 families in the Sulu Archipelago. In 1999, the Philippines exported more than 35,000 tons of dried seaweeds (US$ 44M) making the country the 4th largest producer of seaweeds and 8th largest producer of carrageenan in the world. However, improper post-harvest management (i.e. cleaning; drying by salting or steaming; adulteration of seaweeds with sand, dust, and dirt for added weight; storage; and baling) reduces quality, which eventually dictates the market price. The National Seaweed Planning Workshop was organized by a collaborative effort of SEAFDEC Aquaculture Department (AQD) and the Bureau of Fisheries and Aquatic Resources (BFAR) for the formulation of a Code of Practice for the Seaweed Industry in order to minimize industry malpractices and to sustain its position in the international market. The National Seaweed Planning Workshop invited several seaweed industry associations, and representatives from the government, NGOs and academic and research organizations conducting seaweed research and development to discuss the research and development programs of the different participating agencies, identify and validate problems and concerns of the seaweed industry, and agree on strategies of solving problems in seaweed farming like disease management, post-harvest facilities and research funding. This proceedings documents the National Seaweed Planning Workshop. Hopefully, the contributions would help in the drafting of the Code of Practice in attaining a sustainable seaweed industry.
