摘　　要：为探讨2种不同饲料对珍珠龙胆石斑鱼幼鱼生长、抗氧化及脂质代谢的影响,实验选取初始体质量为(191.47±3.70)g的珍珠龙胆石斑鱼幼鱼10 542尾,随机分成2个处理组,每个处理组3个重复,每个重复1757尾,分别投喂商品专用配合饲料和冰鲜太平洋玉筋鱼,养殖75 d。结果显示,冰鲜太平洋玉筋鱼组的增重率(WGR)、特定生长率(SGR)、肥满度(CF)、饲料系数(FCR)及全鱼脂肪含量显著高于商品专用配合饲料组,肝体比(HSI)和脏体比(VSI)显著低于商品专用配合饲料组,存活率(SR)和蛋白质效率(PER)与商品专用配合饲料组差异不显著。商品专用配合饲料组的甘油三酯(TG)、血清总胆固醇(CHO)、低密度脂蛋白胆固醇(LDL-C)含量显著低于冰鲜太平洋玉筋鱼组;而谷丙转氨酶(GPT)和谷草转氨酶(GOT)的活性显著高于冰鲜太平洋玉筋鱼组。相对冰鲜太平洋玉筋鱼而言,商品专用配合饲料组肝脏超氧化物歧化酶(SOD)、总抗氧化能力(TAOC)、过氧化氢酶(CAT)和脂肪酸合成酶(FAS)的活性显著降低,脂蛋白脂酶(LPL)活性显著升高,但是苹果酸脱氢酶(MDH)和肉碱棕榈酰转移酶-Ⅱ(CPT-Ⅱ)在2组饲料间差异不显著。研究表明,在本实验条件下,冰鲜太平洋玉筋鱼更适合投喂珍珠龙胆石斑鱼幼鱼,商品专用配合饲料对珍珠龙胆石斑鱼幼鱼肝脏产生了不利的影响,因此,建议参考冰鲜太平洋玉筋鱼优质的营养特性,优化和调整珍珠龙胆石斑鱼幼鱼的营养配方。This study was conducted to determine the effects of commercial compound diet and fresh frozen Ammodytes personatus on growth,antioxidant ability and lipid metabolism of hybrid grouper（Epinephelus fuscoguttatus ♀×E.lanceolatus ♂） juveniles.Ten thousand five hundred and forty-two groupers[initial average weight（191.47±3.70） g]were randomly divided into two groups with three replicates at a stock density of one thousand seven hundred and fifty-seven,and commercial compound diet and fresh frozen A.personatus were allocated to each of two groups of fish for a feeding period of 75 days.The results showed that the weight gain rate（WGR）,specific growth rate（SGR）,condition factor（CF）,feed conversion ratio（FCR） and whole body fat content of hybrid grouper juveniles fed with fresh frozen trash fish group were significantly higher than those of fish fed with commercial compound diet（P〈0.05）,and the hepatosmatic index（HSI）,viscerosomatic index（VSI） were significantly lower than those of commercial compound diet group（P〈0.05）.But the survival rate（SR） and protein efficiency ratio（PER） had no difference between fresh frozen trash fish group and commercial compound diet group（P〈0.05）.The contents of total cholesterol（CHO）,triglyceride（TG）,and low density lipoprotein cholesterol（LDL-C） in serum of commercial diet group were significantly decreased compared with fresh frozen A.personatus group（P〈0.05）.The activities of glutamic-pyruvic transaminase（GPT） and glutamic-oxaloacetic transaminase（GOT） in commercial compound diet were significantly higher than those of fresh frozen A personatus group（P〈0.05）.There was an obvious decrease in levels of superoxide dismutase（SOD）,total antioxidant capacity（TAOC）,catalase enzyme（CAT） and fatty acid synthase（FAS）（P〈0.05）,and a significant increase in activity of lipoprotein lipase（LPL） was observed in commercial diet group（P〈0.05）,while the levels of malic dehydrogen
