한국 서남해안 완도해역의 유용 해양 무척추동물자원의 분포

Abstract

The present study was performed to elucidate the distribution of marine invertebrates useful for the materials of pharmacological natural products in Wando, south-western coast of Korea. The study was based on the field survey in 2006 with investigating the materials deposited in the Department of Biology, Chosun University, collected from Wando area since May 21 in 2000. Field survey was carried out at 10 study stations, of which six on rocky shore and four on mud intertidal flat, during the period from August 7 to September 23 in 2006. At each stations quantitative sampling were made from different tidal levels along transect line by the quadrate and corer smapling, with qualitative random sampling method. Total 212 invertebrate species were identified in the present study. In rocky shore area total 152 species comprising 84 molluscs, 39 arthropods, 9 echinoderms, 7 cnidarians, 6 poriferans, 6 bryozoans, and 1 brachipod were occurred, while total 68 species consisted in 40 molluscs, 18 arthropods, 5 echinoderms, 2 poriferans, 1 cnidarian, 1 brachiopod, and 1 nemertean were occurred in mud intertidal flat. The occurrence of taxa was presented with the number of species occurred, the distribution of biomass, and the diversity index of invertebrate community at each study stations. In addition, the distribution of useful taxa such as sponges, cnidarians, bryozoans, molluscs, and tunicates in the study area of Wando was referred with the possibility of utilization as a source of marine natural products. The study area is seems to be still retained a large biodiversity of intertidal invertebrates. Careful management with long-term biological monitoring is needed to reserving the valuable biological resources for sustainable development in Wando area.
