Abstract: The contents of nutritive compositions were measured in muscles of Acipenser guldenstadti, A. ruthenus, A. sinensis, A.schrencki, Huso dauricus, and hybrid sturgeon (H.dauricus ♀× A.schrencki ♂) farmed in Sturgeon Breeding and Technological Engineering Center at Fangshan in Beijing. The results showed that the contents of crude protein, crude lipid, crude ash and moisture were 16.68%-21.72%, 1.00%-5.70%, 1.10%-1.19%, and 71.50%-80.60%, respectively. There were 18 kinds of amino acids in muscles of six sturgeon species, eight essential amino acids and four delicate amino acids of which accounted for 6.67%-9.19% and 6.31%-8.30% in total amino acids, respectively. There were 9 classes (13 kinds) of fatty acids in muscles of the six species.
