득량만 키조개, Atrina pectinata의 양성밀도에 따른 성장과 생존율 = Density Dependent Growth and Survival Rates of Atrina pectinata in Duekryang Bay, Korea

다국어 초록 (Multilingual Abstract)

Growth and survival rates dependent on the density of a pen sell, Atrina pectinata were measured from
Duekryang bay in Korea. Annual water temperature and salinity of the study area were ranged from 14.5 to 28.0℃
and from 27.98 to 31.89 psu, respectively. The pH, DO, COD, DIN, Chl-a and SPM in the study area ranged from
7.78-8.35 mg/L, 7.07-7.90 mg/L, 1.20-1.70 mg/L, 2.88-6.02 mg/L, 0.20-0.79 mg/L and 10.8-21.4 mg/L. The IL,
COD and AVS in sediments ranged from 4.0-4.6%, 7.28-10.76 mg/L and 0.03-0.05 mg/L respectively. The daily
growth rate of shell height and total weight were 0.27%, 0.33% (5 indiv./m²), 0.26, 0.29% (10 indiv./m²) and 0.21,
0.20% (35 indiv./m2). The survival rate also decreased along the density gradient; highest at the lowest density of 5
indiv./m² and lowest at the maximum density of 35 indiv./m².
