신안군 지도 인근 해역의 저서다모류군집 분포 = Distribution of Benthic Polychaetous Community around Ji Island, Sinan-Gun, South-western Coast of Korea

다국어 초록 (Multilingual Abstract)

The present study was carried out to investigate the composition and the distribution of the macrobenthic polychaetous community around Sinan-Gun, on the south-western coast of Korea. An investigation on the macrobenthic polychaetous community in the study area was conducted in April of 2005. In the study area, benthic macrofaunal community was investigated on the base of the samples from 15 stations. The mean density of macrobenthic animals were 283 ind./㎡. There were 39 species and 144 ind./㎡ of polychaetes as the most major faunal group in the study area. At the region between Saok Is. and Ji Is., the density were higher, while lower at the other area of the study area. The most dominant benthic polychaetes in the study area was Pseudopolydora sp.(21 ind./㎡, 14.9%), and followed by unidentified Spionids(13 ind./㎡, 9.3%), Terebellides horikoshii(12 ind./㎡, 8.1%), Lumbrineris longifolia(11 ind./㎡, 7.9%), Heteromastus filiformis(9 ind./㎡, 6.0%), Tharyx sp.(9 ind./㎡, 6.0%) and so on. The most of the predominant species consist of an opportunistic species. Though the density of a common opportunistic species is often very high in the coast of Korea but it is not like that in the study area. The distribution of BPI and BC values, used to assess benthic pollution, showed similar patterns. BPI values were lower and BC values were higher around Ji Is. This result indicates that the structure of benthic community around Ji Is. was unstable. However, it is insufficient in investigation of once in order to examine the complex benthic community system. Consequently, much more research is needed to further examine the marine benthic communtiy.
