There are 231 fishing ports and harbors along the coast of Taiwan now and utilize the phenomenon on the low side of function as to some fishing ports and harbors. This research intends to investigate a practical evaluation index for breakwater reduction based on the functions of fishing ports and the re-utilization of coastal space, the factors of security of fishing ports, fishing environment, development of tourism and some other factors are taking into account while evaluating the breakwater. In the research approach, the statistic data of usability ratio on the breakwaters at the fishing ports in Taiwan is first summarized. Then, to investigate the visiting scholar different fields, such as expert, government's fishing policy unit and fisherman's group, etc. The factors for evaluating breakwater reduction and the weighting number for the standard quantification of evaluation indices are proposed and the feasibility is confirmed with the statistic analysis. Furthermore, the evaluation criteria for the implementation of the construction methods of breakwater reduction in a fishing port is devised, and the breakwater reduction at Hemei Fishing Port is taken as a demonstrative example to analyze the achievement of reduction work, hoping to provide the reference basis for the fishing port facility reduction works evaluation by each level of fishery authorities and to achieve the requirements of the policy for the reduction of water-breaking to construct the decrement of things.

Samples including surface sediments and seawaters were collected from eighteen ports of Pingtung County. The objective of this study were to understand sources of organotin pollution and to monitor the organotin pollution of these fishing ports by analying with gas chromatography-flame photometric detection (GC-FPD). ¡@The results showed that butyltins were the major components of organotin pollution of the fishing ports investigated. The concentrations of MBT, DBT, TBT and MPT in seawaters varied between 3.9~51.6 ng/L as tin, ND~15.2 ng/L as tin, ND~23.9 ng/L as tin and 2.1~7.2 ng/L as tin. The concentrations of MBT, DBT, TBT and MPT in surface sediments varied between 67~332 ng/g as tin, 17.6~325 ng/g as tin, 26~420 ng/g as tin and ND~43.7 ng/g as tin. ¡@The contents of organotin compounds were relevant to the number of fishing craft and the frequency of fishery activities. Distribution of organotin compounds between seawaters and surface sediments in these fishing ports were correlational. Phenyltin was detected only in a few ports, probably due to the sewage discharge from the nearby villages. The concentrations of organotin compounds observed in this study are lower than most of the reported values from foreign ports. In comparison with the previous studies in the same areas, organotin concentrations have dropped significantly. These observations are attributed to the effective control over the utilization of organotin compounds by the authorities.

La preocupación por el Medio Ambiente y las consecuencias que su degradación pueda acarrear a las personas y a los bienes, se ha generalizado en las últimas décadas más que ningún otro sector. En la actualidad, ninguna actividad puede desarrollarse sin respetar el medio ambiente. La gestión de los puertos marítimos no ha sido ajena a esta tendencia y no han escapado tampoco los puertos pesqueros o deportivos donde también es necesario minorar cualquier forma de contaminación si se quieren limitar sus efectos negativos sobre el medio. La preocupación sobre los efectos repercutidos al medio ambiente, importarán los impactos negativos que las actividades pesqueras y de ocio repercutan, sea sobre recursos comunes o sobre el tejido social, a través de riesgos ambientales o sanitarios en sentido amplio, sobre la capacidad del entorno para absorber y regenerar desechos o sencillamente, para producir satisfacciones estéticas o de otro tipo. Los costes derivados de esos impactos dejarán, de ser externos al mercado y de ser sufragados por el conjunto de los ciudadanos, ya que afectarán directamente en buena medida, a las empresas turísticas. La calidad ambiental, pasará a ser clave para el éxito de un turismo de calidad y de muchas actividades de ocio, ya que la demanda de entornos no degradados implica la de una calidad ambiental alta, no sólo para turistas en el sentido estricto de la palabra, sino para cualquier “consumidor de ocio”. / Concern for the Environment and the consequences that might cause degradation to persons and property, has become widespread in recent decades than any other sector. At present, no activity can take place without respecting the environment. The management of seaports has not been immune to this trend and have not escaped either or sport fishing ports where it is also necessary to lessen any form of contamination if you want to limit their negative effects on the environment. Concern about the effects passed on to the environment, import the negative impacts of fishing activities and recreational impact, whether common or resources on the social fabric, through environmental and health risks in a broad sense, on the ability of the environment to absorb and regenerate waste or simply to produce aesthetic satisfaction or otherwise. The costs of these impacts will, if external to the market and be borne by all citizens, as it directly affects largely to tourism businesses. The environmental quality will be key to the success of a quality tourism and many leisure activities, as the demand for non-degraded environments involves a high environmental quality, not only for tourists in the strict sense of the word but for any "consumer of leisure".
