摘  要：
达氏鳇是一种营养价值、经济价值很高的大型淡水鱼类。本文分析了人工养殖和野生达氏鳇的肌肉营养成分。结果表明:人工养殖和野生达氏鳇肌肉中的粗蛋白含量分别为15.90%和16.67%,粗脂肪含量分别为3.94%和2.22%,粗灰分含量分别为5.82%和5.42%,水分含量分别为73.16%和74.42%。野生达氏鳇的饱和脂肪酸(SFA,28.36%)和单不饱和脂肪酸(MUFA,36.85%)显著高于养殖的SFA(18.45%)和MUFA(27.47%),而野生达氏鳇的多不饱和脂肪酸(PUFA,26.26%)显著低于养殖的PUFA(29.97%),人工养殖达氏鳇的二十碳五烯酸和二十二碳六烯酸(EPA+DHA)含量显著低于野生的EPA+DHA含量,分别为9.32%和14.10%;人工养殖和野生达氏鳇肌肉中均含有18种氨基酸,必需氨基酸含量分别为40.28%和40.00%,鲜味氨基酸含量分别为33.51%和32.87%。

摘  要：
Huso dauricus is a species of large freshwater fishes with high nutritional and economic value. The nutritional components of wild and cultured H. dauricus were analyzed in the study. The results showed that crude protein content in muscle of cultured and wild H. dauricus was 15.90 and16.67%,respectively; fat content 3. 94 and 2. 22%; ash content 5. 82 and 5. 42%; water content73. 16 and 74.42%.The SFA and MUFA of wild H. dauricus and cultured H. dauricus were 28.36 and 36.85% and 18.45 and 27.47%,respectively. SFA and MUFA of cultured H. dauricus was significantly lower than those of wild H. dauricus(P <0.05),while the PUFA(26.26%) of wild H.dauricus lower than that of cultured H. dauricus(29.97%). The EPA and DHA of wild and cultured H. dauricus were significant difference(P < 0. 05) being at 9. 32 and 14. 10%,respectively. There were 18 amino acids in both cultured and wild H. dauricus,of which essential amino acid contents were 40.28 and 40.00%,and tasty amino acid contents were 33.51 and 32.87%,respectively.
