摘　　要：对野生与养殖驼背鲈肌肉的营养成分进行比较。结果表明,养殖驼背鲈肌肉中的水分含量、干物质含量、粗蛋白含量、粗灰分含量等与野生驼背鲈相比没有明显区别(P>0.05),而养殖驼背鲈肌肉中粗脂肪含量高于野生驼背鲈(P<0.05)。脂肪酸中不饱和脂肪酸(UFA)含量、鲜味氨基酸(FAA)含量明显低于野生驼背鲈(P<0.05),但是必需氨基酸(EAA)含量高于野生驼背鲈。因此从营养角度看,养殖驼背鲈不仅主要粗营养成分与野生驼背鲈相近,而且人体必需氨基酸含量更高。但是由于养殖驼背鲈比野生驼背鲈肌肉中脂肪含量高,且脂肪酸中不饱和脂肪酸含量和鲜味氨基酸含量较低,因此在口感方面味道没有野生驼背鲈鲜美,且油腻感较强,一定程度上影响了风味。Compared the nutritive components of wild and farmed Chrornilepte.s altivelis. Results showed that the muscle moisture, dry matter, crude protein and crude ash content of the farmed C. altivelis had no obvious difference with the wild （ P 〈 0. 05）, while crude fat content was significantly higher than that of the wild C. altivelis （P〈0. 05）. The UFA content in fatty acids and the FAA content of the farmed C. altivelis, were significantly lower than that of the wild C. altivelis （P〈0.05） ,but the EAA content was significantly higher than that of the wild C. altivelis （P〈0.05）. So not only the nutritional composition content of the the farmed C. altivelis was the same as the wild,but also EAA content was higher than that of the wild C. altivelis form the nutritional point. Because of the crude fat content of the farmed C. altivelis were significantly higher than that of the wild C. altivelis, while the UFA contents in fatty acids and the FAA content of the farmed C. altivelis were significantly lower than that of the wild C. altivelis. So the moutMeel in flavor and creasy of the farmed C. altivelis were slightly worse than the wild C. altivelis, what exercised a malign influence on flavor of the C. altivelis.
