This study compared that the nutrient composition of two domestic commercial Yesso scallop (Korea: Gangneung hanging culture, Pohang sowing culture) and one imported commercial Yesso scallop (Japan: Hokkaido sowing culture), which are distributed on the east coast of Korea, for increasing their value and efficient utilization. The crude lipid content of carcass was 0.11-0.32%, the lowest among the proximate composition. A total of 18 amino acids were identified, the glutamic acid was the highest content of 13.9-14.6% of the total amino acids. A total 27 free amino acids were identified, free glycine content was highest at 34.3-42.9% of the total free amino acids. Eicosapentaenoic acid (EPA, C20:5n-3) and docosapentaenoic acid (DHA, C22:6n-3) content of Gangneung hanging culture scallop were highest at 326.2 ± 38.04 mg/100 g and 195.7 ± 23.10 mg/100 g in total fatty acids of scallops, respectively. Vitamin B2, niacin, sodium, potassium and magnesium content were significantly affected by habitats. Based on these results, each nutrients composition was affected by habitats and culture method. However, all Yesso scallop used for analysis were low fat seafoods and considered to be high-quality food rich in EPA and DHA.
