Community Structure of Macrobenthic Invertebrates of Fishing grounds in the coastal waters of Jeju Island

摘要: ABSTRACT This study was performed to know and compare the community structures of macrobenthic invertebrates eight fishing grounds in coastal waters Jeju Island from September October 2008. A total 166 species identified. Mollusks comprised 77 (46.4%); Arthropods 24 (14.5%), Cnidarians 18 (10.8%); Poriferans 16 (9.6%); others including Echinoderms 33 (17.7%). Density biomass were estimated be 6,905 ind./m 2 113,100.7 gwwt/m , respectively. Gastropods most dominant taxon terms abundance (3,311 ) number as well, predominant (55,789.2 ). The Omphalius pfeifferi Astralium haematragum Turbo cornutus Ergalatax contraacta Lithophaga cura Anthocidaris crassispina Herdmania monus 5-15 m. Based on cluster analysis, area could divided into two station groups. biodiversity, evenness richness index appeared follows: H' = 1.59-2.95, E' 0.38-0.87, R 3.3-10.4. dominance highest Daepo lowest Woljeong.
