Abstract: In this paper, the basic nutrients, amino acids, fatty acids and minerals of Mercenaria mercenaria were determined and analyzed. The results showed that the moisture content of the M. mercenaria was 86.37%, and the content of protein, fat and ash in the dry base were 66.92%, 6.21% and 16.96% respectively. A total of 21 fatty acids were detected, including 10 saturated fatty acids(SFA), 4 monounsatura-ted fatty acids(MUFA)and 7 polyunsaturated fatty acids(PUFA). The content of unsaturated fatty acid was 52.88% of the total fatty acids. The content of EPA and DHA was 65.10% of the PUFA, 27.18% of the total fatty acids. 16 amino acids were detected. The content of delicious amino acid was about 40.82% of the total amino acids. The EAA/TAA was 35.79% and the EAA/NEAA was 55.7%. The contents of Na, Ca, K, Mg were rich. In summary, the nutritional value of the M. mercenaria was high.
