Intertidal zone affected by tidal action are dynamic ecosystems, providing foods and habitats for many organisms. Macroinvertbrates, vital part of these ecosystems, have advantages that evaluate and assess conditions of marine and estuarine environment. The study about spatial and temporal fluctuations of macroinvertebrate communities is essential to understand intertidal ecosystem.
This study was performed to understand macroinvertebrates communities in intertidal area of Hampyeong Bay and Suncheon Bay during the period from May to October in 2010. The stations in Hampyeong Bay consist of two rocky shore transect lines (H1, H2) and one sand-mud flat transect line (H3) and the stations in Suncheon Bay consist of one station that including two vegetative communities (S1-1, S1-2), Suaeda japonica and Phragmites communis, and one mud flat transect line (S2).
Hampyeong Bay appeared difference between each communities according to sediment type. In St. H1 and H2, the macroinvertebrates comprised a total of 79 species and showed the mean density was 1339.2 ind./0.25m2, biomass was 426.28 g/0.25m2. Stations of rocky shores appeared certainly zonation according to the tidal level. Chthamalus challengeri, Balanus albicostatus, Littorina brevicula at the high intertidal zone, Littorina brevicula, Modiolus elongatus, Balanus albicostatus at middle intertidal zone, polycheates at low intertidal zone were dominated.
The low intertidal zone on general rocky shore have growth with brown algae but those of H1 and H2 consisted with mud sedimentary layers. Macroinvertebrates of H3, sand-mud flat, comprised a total of 75 species and showed the mean density was 285.9 ind./0.25m2 biomass was 19.33 g/0.25m2. Sand-mud flat (H3) dose not appear zonation such as rocky intertidal zone (H1, H2). Polychaetes emerged with highest mean density and gastropods emerged with highest biomass.
The sediment of Suncheon Bay is consisted with mud sedimentary layer. Macro- invertebrate community comprised a total of 25 species and showed that the mean density was 19.5 ind./0.25m2, biomass was 7.37 g/0.25m2. Invertebrates were irregularly distributed in mud flat of S2. Crustraceans appeared high mean densities in all study stations of Suncheon Bay. When compared Suaeda japonica and Phragmites communis communities, number of species occurred, mean density and biomass on Phragmites communis communities are higher than those on Suaeda japonica communities because of high productivity.
Long term study based on a regular sampling period are necessary to confirm fluctuation aspects and fine features of invertebrate communities in Hampyeong Bay and Suncheon Bay.
