East-West Environment and Policy Institute Research Report No. 4 Fishery Management and Extended Maritime Jurisdiction: The Philippine Tuna Fishery Situation by Virginia L. Aprieto East-West Center Honolulu, Hawaii THE EAST-WEST CENTER—officially known as the Center for Cultural and Technical Interchange Between East and West—is a national educational institution established in Hawaii by the U.S. Congress in 1960 to promote better relations and understanding between the United States and the nations of Asia and the Pacific through cooperative study, training, and research. The Center is administered by a public, nonprofit corporation whose international Board of Governors consists of distinguished scholars, business leaders, and public servants. Each year more than 1,500 men and women from many nations and cul• tures participate in Center programs that seek cooperative solutions to prob• lems of mutual consequence to East and West. Working with the Center's multidisciplinary and multicultural staff, participants include visiting scholars and researchers; leaders and professionals from the academic, government, and business communities; and graduate degree students, most of whom are enrolled at the University of Hawaii. For each Center participant from the United States, two participants are sought from the Asian and Pacific area. Center programs are conducted by institutes addressing problems of com• munication, culture learning, environment and policy, population, and re• source systems. A limited number of "open" grants are available to degree scholars and research fellows whose academic interests are not encompassed by institute programs. The U.S. Congress provides basic funding for Center programs and a va• riety of awards to participants. Because of the cooperative nature of Center programs, financial support and cost-sharing are also provided by Asian and Pacific governments, regional agencies, private enterprise and foundations. The Center is on land adjacent to and provided by the University of Hawaii. THE EAST-WEST ENVIRONMENT AND POLICY INSTITUTE was established in October 1977 to increase understanding of the interrelationships among policies designed to meet a broad range of human and societal needs over time and the natural systems and resources on which these policies depend or impact. Through interdisciplinary and multinational programs of research, study, and training, the Institute seeks to develop and apply concepts and approaches useful in identifying alternatives available to decision makers and in assessing the implications of such choices. Progress and results of Institute programs are disseminated in the East-West Center region through research reports, books, workshop reports, working papers, newsletters, and other educational and informational materials.

This part presents the ocean assets, activities, policies, and problems of one country (the Philippines) as they relate to fisheries man• agement and the emerging regime of extended maritime jurisdiction. The tuna-fishing industry was studied for two reasons: first, tunas comprise the most important commercial fishery of the country; and second, this resource is transnational in distribution and therefore likely to transcend national maritimejurisdictional boundaries. While the tuna-fishing industry is not new in the Philippines, data in a useful form are difficult to find or, when available, are not always compre• hensible or reliable. This situation can exist in other countries in the region as well. In undertaking this study, therefore, existing reports and data were evaluated against actual field situations and information. The author spent two months traveling to fishing ports, markets, and villages in the Philippines, witnessed fishing and fish-landing operations, and interviewed fishermen, managers, entrepreneurs, and government offi• cials. The study reveals many deficiencies in fisheries management policies and practices in the country, as well as the mounting problems the Philip• pines faces in dealing with its neighbors in relation to the use of a shared resource. The deficiencies and problems appear common to most, if not all, the countries within the area of present concern to EAPI. The Philippine case, therefore, provides important first insights into present and future trends in fishery interest and resource use in the Southeast Asian seas —transnational ocean management and the poten• tial problems and opportunities for subnational, national, and interna• tional action and interaction.
