The basic nutritional composition,amino acid composition,fatty acid composition of gonads from male and female Acipenser gueldenstaedti were determined to provide information for their high value- added utilization. Results indicated that testis contained 75.20% of crude fat,9.06% of crude protein and 0.10% of ash.Whereas,ovary contained 42.00% of crude fat,5.96% of crude protein and 0.20% of ash. For protein of testis,essential amino acids accounted for 36.80% of total amino acids. Whereas,the corresponding value for protein of ovary was 35.00%.For testis,eicosapentaenoic acid( EPA) and doco- sahexaenoic acid( DHA) accounted for 7.41%of total fatty acids. Whereas,the corresponding value for ovary was 7.25%. In summary,gonads from Acipenser gueldenstaedti rich in lipids,and lipids should be the major targets for their comprehensive utilization.
