Seasonal variations in the body weight and biochemical composition of Crassostrea talienwhanensis were studied over a period of 6 months. Basic chemical constituent results indicated that protein content in Jun 2011, glycogen content in Apr 2011 and lipids content in Feb 2011 were highest in 6 months. Taurine was the predominant free amino acid in C. talienwhanensis, at concentrations of 6969.72-9536.47 mg/100 g dry sample. Glutamic acid was the predominant component of total amino acid in C. talienwhanensis, at concentrations of 5696.77-6308.94 mg/100 g dry sample. The polyunsaturated fatty acid (PUFA) was predominant fatty acid in total lipid of C. talienwhanensis comparing with other fatty acids. Based on all analyses of C. talienwhanensis from Dalian Bay, protein, glycogen and lipid contents were different in 6 months. These analysis data, including biochemical composition, free amino acids, total amino acids and fatty acids might be useful parameters to processing industry of C. talienwhanensis.
