This study aimed to analyze flesh quality traits of wild and farmed Sinonovacula constricta in Sanmen Bay, including crude protein, moisture, crude fat, ash, amino acid, fatty acid, texture and colour. The results showed that moisture, crude protein, crude fat and ash had significant differences between wild and farmed Sinonovacula constricta in Sanmen Bay (P<0.05). The composition and content of amino acids in muscle had difference between wild and farmed Sinonovacula constricta. The higher amino acids contents of farmed Sinonovacula constricta arranged in the following order: glutamic acid> aspartic acid>lysine>arginine>leucine>alanine>valine>glycine; The higher amino acids content of wild Sinonovacula constricta arranged in the following order: glutamic acid> aspartic acid> alanine> leucine> lysine> arginine> glycine> valine. The components and contents of fatty acid did not have the same diversification in wild and farmed Sinonovacula constricta, but the total percentage of polyunsaturated fatty acid content in wild was higher than that of farmed Sinonovacula constricta. Texture profile analysis with different areas of wild and farmed Sinonovacula constricta was experimented, and the results showed that the adhesiveness and springiness of visceral and foot muscle of farmed better than wild Sinonovacula constricta(P<0.05). However, the colour of muscle showed no significant difference between wild and farmed Sinonovacula constricta (P>0.05). Hence, it is concluded that farmed Sinonovacula constricta show better size, dressing percentage and texture than wild Sinonovacula constricta, but lower nutritional value than wild Sinonovacula constricta in Sanmen Bay.
