Abstract The purpose of this research is to investigate the ocean¡¦s sustainable uses and explore new development potentials for the Taiwanese fishing industry. In addition, several possible options are proposed, while the strategies for the operability and development of the Southern Ocean Park are discussed. Furthermore, analyses of the operations at the Little Ryukyu Demo Region, the preliminary demonstration site for the Southern Ocean Park, are performed and assessed. This research begins by analyzing the oceanic industries both in Taiwan and around the world, and then continues to examine ocean maricultures and aqua-farms. Legal regulations pertaining to the fishing industries are also investigated to assess the future and the potential of the Southern Ocean Park. The research draws the following key conclusions: 1. The ocean provides an important basis of development for Taiwan in its expansion of land use. 2. Current development of ocean use and relevant industries around the world are already showing progressive trends in a diversity of industries and fronts. 3. The Southern Ocean Park utilizes netted marine aqua-farms as a main developmental focus. However, opportunities to continue development in various oceanic industries in the future are greatly desired. 4. The netted marine aqua-farms are suitable for the growth of Taiwanese fishing industry, but are faced with the following issues: (1.) The degree of ocean pollution, although less than land-based mari-cultures and fisheries, are still an important and a necessary issue to address. Improvements to farming and feeding technologies will be required to reduce the environmental impact. (2.) The legal use of oceanic territories, especially pertaining to the regulation and security of netted marine aqua-farms, still await numerous bills to be passed. (3.) Faced with competition from other countries, a lack of immediate effort in Taiwan may result in losing the benefits and advantages of the netted marine aqua-farms. 5. The legal proceedings for the Southern Ocean Park have been categorized as part of the legislative group under the Ocean Administration Development Committee of the Executive Yuan. 6. The following presents key strategies in the development of the Southern Ocean Park: (1.) With the success of the Ryukyu Demo Region, the development can then be extended to other oceanic territories. The acquisition of such experience can serve to maximize the success rate of future, large-scale oceanic developments in other regions. (2.) Prime promoters of the Southern Ocean Park should persuade the higher-level government offices to draw attention and focus for the development of sustainable use of the environment and the bigger picture, rather than a singular development meant only for the fishing industries. This is the only way to acquire more resources and support from other offices and committees. (3.) After President Chen declared an increased effort to elevate oceanic industries in the south, the Southern Ocean Park has declined over time to its current status as an unimportant pending policy. Committed individuals must join forces with the legislative and scholar branches to apply continuous pressure on the Fishing Administration Department. This is the only way to successful stimulate proper development in the fishing industry. (4.) The Ryukyu Demo Region and other future regions should collect the local resources, especially those pertaining to tourism, and progress toward joint-industry developments. Consequently, the local communities will generate greater support, and bigger economic growth can then be expected.
