N/A The fauna associated with mussel (Mytilus galloprovincialis) beds and vertical distribution of macrobenthos were studied on the Goijeong rocky shore in Jinhae Bay, Korea. Sampling was conducted seasonally using a quadrate from January to October, 1998. In the first experiment to reveal the community structure of macrobenthos in mussel bed, a total of 62 species (10,690 ind./㎡ , 3,802.1 g/㎡) were identified, which included polychaetes (32 spp., 52.6%), molluscs (16 spp.), crustaceans (10 spp.), and others. The density-dominant species were Pseudopolydora antennata, Nereis heterocirrata, Littorina brevicula and Balanus kondakovi. And the density of associated fauna was correlated with that of mussel (r=0.951, P=0.049). In the second experiment, to reveal the vertical distribution of macrobenthos on the rocky shore, ANOVA showed highly significant differences between the density of top 5 dominant species (Chthamahw challengeri, Littorina brevicula, Balanus kondakovi, Septifer virgatus and Granulilittorina exigua) and tidal levels (P= 0.000). Vertical distribution of macrobnethos was characterized by Chthamalus belt and Balanus-Septifer belt in the mussel bed.
