摘　　要：为研究池塘内循环流水(IPA)养殖模式对黑鲷(Acanthopagrus schlegelii)肌肉品质的影响,对采用IPA模式和传统池塘模式(TPA)养殖的两组黑鲷进行随机抽样、取样,分别进行了常规营养成分、氨基酸、脂肪酸组分的测定和分析。结果显示:IPA组粗蛋白含量极显著(P<0.01)高于TPA组,IPA水分含量显著低于TPA组(P<0.05),IPA组粗脂肪和灰分含量高于TPA组,差异不显著(P>0.05)。IPA组和TPA组黑鲷肌肉中均检出17种氨基酸,其中人体必需氨基酸7种,每种氨基酸含量IPA组均极显著高于TPA组(P<0.01),必需氨基酸指数分别为84.32和76.90,第一限制性氨基酸均为蛋氨酸+半胱氨酸。两组黑鲷均检出脂肪酸10种,其中饱和脂肪酸3种,单不饱和脂肪酸3种,多不饱和脂肪酸4种。饱和脂肪酸、单不饱和脂肪酸IPA组均高于TPA组,差异不显著(P>0.05)。多不饱和脂肪酸IPA组低于TPA组,差异显著(P<0.05)。研究表明,IPA养殖模式可以明显提高黑鲷肌肉蛋白质营养价值,但降低了多不饱和脂肪酸的含量。To study the effect of Internal-circulation pond aquaculture(IPA)culture mode on the muscle quality of Acanthopagrus schlegelii,two groups of Acanthopagrus schlegelii cultured in IPA and traditional pond aquaculture(TPA)were randomly sampled,and determined and analyzed for conventional nutrients,amino acids and fatty acid fractions,respectively.The results showed that the IPA group has an extremely significantly higher crude protein content(P<0.01)and significantly lower water content(P<0.05)than the TPA group and also a higher crude fat and ash content,although the difference was not significant(P>0.05).Seventeen amino acids were detected in the muscle of both IPA and TPA groups of Acanthopagrus schlegelii,including seven essential amino acids in human,were detected in the muscles of both groups,and the content of every amino acid in the IPA group was significantly higher than that in the TPA group,with amino acid indexes of 84.32 and 76.90.The first limiting amino acid of both groups was methionine+cysteine.Meanwhile,ten fatty acids were detected in both groups,including three saturated fatty acids(SFA),three monounsaturated fatty acids(MUFA),and four polyunsaturated fatty acids(PUFA).The IPA group showed a statistically insignificant higher SFA and MUFA contents(P>0.05),and significantly lower PUFA contents(P<0.05).These results showed that IPA aquaculture mode significantly improved the nutritional value of protein in the muscle of black sea bream,but reduced the contents of PUFA.
