| Summary: | 碩士 === 國立中山大學 === 海洋環境及工程學系研究所 === 97 === Net cages are mainly located on the coastal areas of Peng-hu and Ping-tung counties. Generally, there are two kinds of disasters occurred in the fish farming industries: one is caused by typhoon attack, while the other is caused by human vandalism. This paper is focus on how to prevent the damages induced by poaching or vandalism. Since high-valued fish are raised in the net cages, they are often become the targets of illegal intruders for stealing at night, especially when the net cages are lack of security system. Under such unsecured situation, entrepreneurs would not dare to invest in this industry and may keep a suspicious attitude towards it.
Compare to land aquaculture, marine aquaculture is far more complicated in terms of techniques involved in production progress. Surely over-fishing has serious deplete the stock of biomass in the sea in the past decades. Recently, the skyrocketed oil price even deteriorate the fishing industry to such a level that fishing boats can only operate for a season in each year and end up losing money. However, Fisheries Agency has planned to recycle commercial fishing boats, and hopefully by doing so, this aquacultural industry will turn into a new trend in the near future.
This research looks into 700 hectares of net cage park, Southern Oceanic Park, and suggests that the fishery authority turn this area into special district, adjust the fishery law, designate San-fu port as the park’s operation center, finally set up a security system, then we may reduce the damage caused by unlawful activities.
The geographical make-up of Liu-chiu provides ideal conditions for the present net cage area. The sea waters outside of San-fu port are also blessed with the same geographical advantage. This research looks at “man-made calamities”, namely vandalism and theft, so as to prevent damage and loss and protect resources and equipment. The areas chosen for this study include the surrounding sea waters of Liu-chiu aquaculture zone and the highly representative San-fu fishing port. There are also discussions on the installation of automatic alarm system in the eventual marine park.
As an officer in a law enforcement administration for coastal affaires, my past contact with net cage fishermen revealed the damage and loss they have been undergoing and their sense of helplessness. On top of that, relevant documents turned out to be insufficient. Therefore, this research aims to figure out a way to fill this security gap by integrating public power from governmental services with protection and safety solutions on the part of individuals. To put this initiative to work, it is necessary to map out a special marine park where security mechanism could be automatically triggered by local facilities. This will then allow public power and personal endeavor to work simultaneously in the special zone and prevent any illegal activities. With its high applicability and pertinence, the eventual security system will hopefully entice more entrepreneurs, thus maintaining a sound net cage aquaculture.
