Abstract: Approximate composition，amino acids，fatty acids and mineral elements in an adductor were investigated in rock scallop Crassadoma gigantea bymeans of ordinary nutritive analyticalmethod and compared with the three Chinese scallops including yesso scallop Patiopecten yesoensis，bay scallop Argopecten irradians，and Chlamysfarreri to investigate the nutritive composition of rock scallop.The results showed that there were moisture of 78.68％，crude protein of 16.13％，crude fat of 0.92％，total ash of 1.77％and total carbohydrate of 1.92％in the rock scallop.The contents of ash and crude protein were shown to be higher in rock scallop compared with other three species scallops，while there were lowermoisture and crude fat contents in the rock scallop than those in the three Chinese scallops，with total polysaccharide content being closed to yesso scallop.The rock scallop had essential amino acids（EAA）of5.17％and delicious amino acids（DAA）of7.25％，with EAA/TAA ratio of35.54％and DAA/TAA ratio of 49.82％.The ratio of essential amino-acids to non-essential amino-acids（EAA/NEAA）in adductormuscle of rock scallop was 59.10％，a little higher and closer to ideal amino acid pattern（IAAP）in FAO/WHO than the other three species，indicating that the constitutional rate of the essential amino acidsmet the Food and Agriculture Organization of the United Nations/World Health Organization（FAO/WHO）Standards.The contents of highly unsaturated fatty acids（HUFA）were 48.56％，including the total EPA and DHA contents of 41.84％，higher than that in the three ordinary scallops.The rock scallop had high level ofmineral contents and trace elements，such as K，Mg，Ca and Zn.In conclusion，the rock scallop as a potential aquaculture species is a nutritive and delicious shellfish that is characterized by rich in protein，and poor in fat.
