Abstract:

The proximate composition, amino acid and fatty acid profiles in the muscle of cultivated and wild Sepiapharaonis were analyzed. The results showed that the protein contents in the muscle of cultivated and wild Sepia pharaoniswere 20.24% and 20.15%, respectively, and the total lipid contents were 0.81% and 0.97%, respectively, indicating slightlyhigher abundance under cultivated conditions. The content of total unsaturated fatty acids (UFA) in cultivated Sepiapharaonis was similar to that in the wild one, and eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) togetheraccounted for 37.13% and 33.63% of the total amount of fatty acids, respectively. Both cultivated and wild Sepia pharaoniswere detected to contain 17 amino acids, with total amino acid contents in fresh samples of 18.84% and 18.07%, andessential to total amino acid ratios of 42.83% and 42.00%, respectively.
