In recent year, marine cage aquaculture has rapidly growing in Taiwan. Fast cage farming development results in expanding scale and production in the limited areas. Concentration farming often causes the degradation and over carrying capacity of marine environment. Thus, the investigation of current operation scale of aquaculture activities is urgently needed by the local authority for the better understanding and planning of aquaculture regulation. The survey were conducted to clarify the management status and to discover the unknown question that are relevant to the farming environment and the Fisheries Right which are waiting further study to resolve. Two major cage aquaculture survey sites, LiouCiou and Peng Hu, have been chosen for interviewing and collection of data. The economic assessment approach provides a tool to the establishment of appropriate strategy and method for the achievement of managing the marine cage operations.
Most of aquaculturists in Pen Hu belong to family-owned, in contrast to only one corporate firm which joins the industry for only five years. The corporate firm has less farming experiences than the small scale aquaculturists who have 10-20 years farming experiences. The small scale individual aquaculturists generally have higher survival rate of cobia and efficient productivity of farming. The survey results showed that Peng Hu has longer cage holding period for reaching market size than LiouCiou. According to geographical location, Peng Hu has colder winter temperature and growth delay that require longer time for harvest. The major problem in cage culturing is the impractical and outdated law regulation from the municipal authority. Currently, LiouCiou has invalid regulation regarding to granting the Fisheries Right for culturing. In Peng Hu, the regulation of maximum three hectares per person in law has raised obstacles for aquaculturists who have to acquire someone as dummy account to apply for more farming hectares. Moreover, some still farming aquaculturists have to compete with non-used aquaculturists for granting more site areas where the allowable areas are tied to the limitation by authority. As a result, aquaculturists are devoted to increase the density culture with the risk of over carrying capacity in the limited areas. The study has detected the existing farming problems and presented the following recommendations such as 1) enforcing the implementations of verification, validation, renew and suspension for Fisheries Right, 2) offering low-interest mortgage for farming specially during the weather disaster, 3) enforcing the patrol of marine water to prevent the contraband fish from outside the countries, and 4) designating a farming zone with clear regulation and amended relevantly status quo. At last, aqua culturists should comprehend and adopt the new farming technology, economic assessment, and carrying capacity of farming environment in order to achieve its maximum economic efficiencies.
