제주남부해역 사질대 유용생물 분포특성 = Distribution Characteristic of Exploitable Macrobenthic Invertebrates of Beach Sediments in the Southern Coastal Water of Jeju Island

다국어 초록 (Multilingual Abstract)

This study was performed to know the community structure of macrobenthos and environmental factors at each 16 stations in the subtidal sandy bottoms of the southern coastal water of Jeju Island from July to November, 2011. Mean temperature and mean salinity were 20.2-22.7℃, 33.7-34.9 psu which shows stable water messes. Chlorophyll a concentrations of phytoplankton ranged from 0.71 to 1.71 mg/L (1.11 mg/L), showing higher July than September and November with a blooming in summer. The mean concentration values (the ranges in parentheses) of nitrate, phosphate, and silicate are 0.029-0.206 mg/L (0.101 mg/L), 0.001-0.027 mg/L (0.007 mg/L), 0.024-0.682 mg/L (0.454 mg/L), respectively. However, the values higher coastal zone due to influxes from the land. A total of 37 species was identified. of these mollusca comprised 29 secies (78.4%); Echinodermata 5 (13.5%); Arthropoda 3 (8.1%). density and biomass were estimated to be 550 ind./m2 and 20,951.8 gwwt/m2, respectively. Mollusca were the most dominant faunal group in terms of abundance (481 ind./m2) and number of species as well, whereas bivalves were predominant in biomass (16,647.6 gwwt/m2). The dominant species were Vasticardium burchardi, Oblimopa japonica, Mactar achatina, Bornatemishistrioiw akawai, Paphia vernicosa, Amusium japonicum, Glycymeris albolineata, Astriclypeus manni in 15-30 m. The seasonal variation appeared as distinct, Mollusca of individual and biomass. When summer was make a slow increase, after the highest decrease in autumn. The abundance of macrobenthic invertebrates showed significant correlation with environmental factors (Chlorophyll a, DIN, SiO2, Fine sand, Very fine sand) in almost all sampling depths. The biodiversity, evenness richness index were appeared 1.56-2.50 (H'), 0.49-0.80 (E'), 4.12-4.67 (R) in each stations. The dominace index were appeared Highest in November and lowest in September.

제주도 남부연안 사질대 해역에서 2011년 7월부터 11월까지 16개 정점에 대해 해양환경특성 및 저서 무척추동물의 군집구조를 파악하기 위해 조사하였으며 그 결과는 다음과 같다.
평균 수온과 염분은 각각 20.2-22.7℃, 33.7-34.9 psu로써비교적 안정된 수괴를 형성하고 있었다. 식물플랑크톤의Chlorophyll a 분포는 0.71-1.71 mg/L (평균 1.11 mg/L)의 범위로써 9월과 11월에 비해 7월에 높게 나타났다.
조사기간 중 총 37종의 저서동물이 채집되었으며, 연체동물이 29종 (78.4%) 이였으며, 이 중 이매패류가 17종 (45.9%)로 가장 우점 하였고, 극피동물 5종 (13.5%), 절지동물 3종(8.1%) 의 순으로 나타났다. 조사해역의 개체밀도와 생물량은각각 550 개체/m2, 20,951.8 gwwt/m2로 연체동물 중 이매패류 (481 ind./m2, 16,647.6 gwwt/m2) 가 개체수와 생체량에서 우점 하였다.
주요 우점종은 소쿠리조개, 흰바탕무늬조개, 흰점분홍무늬조개, 갈색점줄떡조개, 밭고랑행달조개, 해가리비, 속갈색조개,구멍연잎성게로 주로 이매패류에서 높은 우점율을 나타냈다.
정점별 종다양도 (H'), 균등도 (E') 및 풍부도 (R) 지수의 범위는 각각 1.56-2.50, 0.49-0.80, 4.12-4.67 로 9월에 가장 낮고, 11월에 높게 나타났다.
