Analysis and evaluation of nutritional composition of Acipenser gueldenstaedti Gonad

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.
