Abstract: In order to ascertain the nutritive value in the muscle ofCharybdis feriatus (Linnaeus) , amino acids composition were detected using the automatic amino acid analyzer. Seventeen kind of amino acids were found in muscle ofCharybdis feriatus (Linnaeus) including 7 kinds of essential amino acids (EAA). In fresh muscle,the content of total amino acids (TAA) was 13.43%, the content of EAA was 5.33%, the percentage of EAA to TAA was 39.69%. Four kinds of delicious amino acids (DAA) accounted for 5.59%, the percentage of DAA to TAA was 41.62%. The value of EAA to NEAA was 0.66. It was clear that the content of the different amino acids was stable and the constitutional rate of the essential amino acids met the Food and Agriculture Organization of the United Nations/ World Health Organization (FAO/WHO) Standard. The amino acids score (AAS) of Lys was the highest and the value was 1.21, more than FAO/WHO Standard. The essential amino acids index (EAAI) ofCharybdis feriatus was 60.94%. The results indicated thatCharybdis feriatus was a nutritive and deli?cious food fish with health care value, and it could be a potential aquaculture species.
