| 摘 要： | 为研究饲料n-3/n-6高不饱和脂肪酸(HUFA)对许氏平鲉幼鱼生长、体组成及组织脂肪酸组成的影响,配制了6种n-3/n-6 HUFA(D1:14.28,D2:9.26,D3:5.66,D4:3.06,D5:2.02,D6:1.50)的等氮等脂的实验饲料。以许氏平鲉幼鱼(36.30±0.03) g为研究对象,在网箱中养殖65 d,分为6实验组,每组设3个重复,每个重复30尾鱼。结果发现:①饲料n-3/n-6 HUFA对许氏平鲉幼鱼的成活率无显著影响。随着n-3/n-6 HUFA降低,幼鱼增重率呈先上升后下降趋势,饲料系数呈相反趋势,D2和D3组的增重率显著高于各组。②全鱼和肌肉粗脂肪含量呈先上升后下降趋势,分别在D2、D3组达到最大值。肝脏粗脂肪含量呈先下降后上升趋势,D2组显著小于其他各组。③各组织C20:4n-6含量随n-3/n-6 HUFA的降低均呈上升趋势,而C20:5n-3、C22:6n-3和n-3/n-6 HUFA整体呈下降趋势。④鱼体脂肪酸组成受饲料影响程度由大到小依次为腹脂、肌肉、全鱼、肝脏,且各组织C20:5n-3与饲料C20:4n-6均呈显著负相关。研究表明,在本实验条件下,饲料中适宜比例(5.66～9.26)的n-3/n-6 HUFA显著提高实验鱼的生长,改变体组成及组织脂肪酸组成,以增重率和饲料系数作评价指标,经一元二次回归分析得许氏平鲉幼鱼饲料中n-3/n-6 HUFA的适宜比例分别是8.93和8.70。
