Abstract
This study was performed in order to obtain basic data of macrobenthic community in continental shelf exclusive economic zone (EEZ), before sand excavation. The species number of macrozoobenthos was 157, mean density was 2,529 ind./$m^2$ and mean biomass was 231.8 $g/m^2$ in November, 2000. The species number of macrozoobenthos was 179, mean density was 3,773 ind./$m^2$ and mean biomass was 391.2$g/m^2$ in February, 2001. Dominant species were Ampelisca sp. and Photis sp. in amphipods, Ophiactis branchygenys in ophiuroids and Nothria sp. and Eunice sp. in polychaetes. In the proportion of feeding types of macrobenthos, surface deposit feeders were most dominant feeding group, and followed by carnivores, subsurface deposit feeders, and filter feeders. Species diversity index (H') was high ranging from 2.5 to 3.5 at most sites.
