Macrobenthic Community around Myodo Island in Gwangyang-Bay

The community structure of macrobenthos was investigated around Myodo Island in Gwangyang-Bay. Macrobenthic animals were collected by using a van Veen grab (0.1m²) from January to August, 2009. The macrobenthic faunal community has 40 species and 151.03inds/m². The dominant species were Ruditapes philippinarum, Didimarca tenebricum, and Mytilas edulis. The diversity index ranged 0-3.539, evenness index was 0.193-1, and richness index was 0-2.474. The highest benthic pollution index was observed at station 7 and 8. All macro-benthic faunas were assigned into a specific functional group according to their ecological responses against the environmental stress.
