摘　　要：比较研究了野生和池养刀鲚(Coilia nasus)肌肉营养成分组成、质构特性和抗氧化特性。结果显示,野生刀鲚肌肉中水分、羟脯氨酸、胶原蛋白含量以及胶原蛋白/总蛋白比值均显著低于池养型,而脂肪含量则显著提高;两者的蛋白质含量、pH均无显著性差异;池养刀鲚肌肉弹性、硬度、咀嚼度、胶着性相较于野生型呈上升趋势,但无统计学差异。野生刀鲚肌肉中SOD、CAT、T-AOC、MDA、GSH-PX、iNOS、GSH/GSSG均显著高于池养型。表明野生和池养刀鲚营养品质存在差异,建议在人工养殖刀鲚中应该注意饵料的种类和丰度,其养殖模式有待进一步改善。The present study compares the muscle mutritional composition,texture and antioxidant capacity in wild and farmed Coilia nasus populations. The results showed that wild fish exhibited a lower content of moisture,hydroxyproline and collagen,and a higher fat content as compared with farmed fish. No significant differences were found for protein content,pH and textural parameters in wild and farmed Coilia nasus,but a tendency toward slightly increased springiness,hardness,chewiness and gumminess were indicated for farmed fish. Moreover,SOD,CAT,T-AOC,MDA,GSH-PX,iNOS and GSH/GSSG in muscle were significantly higher in wild than in farmed fish. Overall,changes in these parameters determine marked differences in the flesh quality of wild and farmed Coilia nasus. The reliable techniques for larval rearing should be improved by a suitable diet based on feed species and density.
