Abstract: This paper studied the contents of nutrition composition of adduct and entrails of Atrina pectinata. The results demonstrated that the adduct was of much higher protein content and much lower ash content than the entrails and also of higher protein content than some common shellfishes. The nutrition composition of the entrails seemed to be similar to common shellfishes. Both bad higher protein nutrient values, because the adduct and the entrails showed the amino acid scores being 83 and 82.7respectively. The contents of inorganic elements of the adduct had its own characteristics. The contents of elements of limit quantity were much higher than those of the adduct. This illustrated that the entrails had stronger capacity in enriching elements of limit quantity than the adduct.

Key words: Atrina pectinata (Linnaeus) , Adduct , Entrails (Soft body) , Amino acid score , Inorganic elements , Elements of limit quantity
