독도 조하대 대형무척추동물의 군집구조

This study was conducted in June and September 2022 to analyze the macrofauna community of Dokdo. The total number of macrofauna in Dokdo is 120 species (annelida 10, arthropoda 30, chordata 1, cnidaria 3, echinodermata 7, mollusca 60, nemertea 1, porifera 7, sipuncula 1), and the average biomass was 3,624.65 g/㎡ in total (annelida 1.20 g/㎡, arthropoda 381.16 g/㎡, chordata 0.38 g/㎡, cnidaria 0.78 g/㎡, echinodermata 32.74 g/㎡, mollusca 3,182.89 g/㎡, nemertea 0.28 g/㎡, porifera 23.75 g/㎡, sipuncula 1.46 g/㎡), and the everage individuals was 376.67 ind./㎡ (annelida 28.89 ind./㎡, arthropoda 224.56 ind./㎡, chordata 0.11 ind./㎡, cnidaria 1.33 ind./㎡, echinodermata 4.44 ind./㎡, mollusca 103.33 ind./㎡, nemertea 0.22 ind./㎡, porifera 1.78 ind./㎡, sipuncula 12.00 ind./㎡). 60 species, 238.37 g/㎡, 135.33 ind./㎡ from haenyobawi, 83 species, 10,038.61 g/㎡, 776.35 ind./㎡ from ddongyeo, 78 species, 596.96 g/㎡, 218.33 ind./㎡ from hogdomgul were investigated. The number of species, average biomass and average individual showed the highest values in ddongyeo. The dominant species of marine macrofauna based on biomass were Mytilus unguiculatus at 2,778.45 g/㎡, Pseudoctomeris sulcata at 279.19 g/㎡, Turbo cornutus at 132.11 g/㎡, Neopycnodonte cochlear at 199.26 g/㎡ and Ostrea circumpicta at 80.86 g/㎡. In both the survey period, Mytilus unguiculatus were the highest at 2,466.19 g/㎡ and 3,090.70 g/㎡, respectively, and it was judged to be a good environment for mussels to inhabit. Research on marine macrofauna in Dokdo has been conducted irregularly in the past, and continuous research and long-term monitoring are needed to accurately determine the community structure.
