Abstract

When constructing and improving fishing ports and communities, fundamental concepts based on ecological aspects are required to recognize the value of the ecosystem and to coexist with nature. As a first step to assess the construction and improvement of fishing ports and communities from ecoIogical viewpoints, We conducted the following surveys and studies. We conducted a questionnaire survey on the natural environments and the living conditions of wildlife in fishing ports, as well as on the habitat conditions of the wildlife listed in the category subject to assessments,in our country. The results are as follows ; 1) The fewer the artificial structures, the more diversity in the topographic features of the surrounding areas. 2) Changes in the number of wildlife were confirmed at more than half the surveyed fishing ports, which is evidence of the ongoing trasitions of the ecosystem. 3) Drastic increases and decreases in the populations of wildlife are likely to occur as the diversities of the nature are smalller. 4) The living conditions of the types of wildlife listed in the category subject to assessments were found. Furthermore, the ecosystem-friendly fishing port construction and improvement method was examined to conserve and restore the ecosystem around fishing ports.
