The nutritive components of Acipenser schrenckii roe were determined by conventional analytical methods. The determination results showed that the crude protein content of Acipenser schrenckii roe was 26.00%. The 18 amino acids content of Acipenser schrenckii roe was 25.21%. Among these amino acids, the essential amino acids content was 10.16% , and the fraction of essential amino acids was approximately 40.30% . The ratio of essential amino acids to non-essential amino acids was 67.51% . Tryptophane, as the first limiting amino acid, scored 92. The unsaturated fatty acids accounted for 62.8% of the total fatty acids, and the EPA and DHA occupied 10.3%. The con
