中文摘要：
试验选择体长、体质量基本一致的6月龄刀鲚，分别投喂日粮1（人工配合软颗粒饲料）、日粮2（人工配合饲料与鱼油混合的软颗粒饲料）及日粮3（人工配合缓沉硬颗粒料）3种配合饲料60d，探讨不同人工饲料对刀鲚幼鱼生长性能、血清生化指标及脂质代谢酶活性的影响．结果表明：日粮2组和日粮3组的幼鱼体质量、体质量增长率、特定生长率和肥满度显著高于日粮1组；日粮3组的饵料系数显著低于日粮1组和日粮2组；各组间体长、体长／体高、体长／体厚、肝体比及脏体比等生长指标及总蛋白、白蛋白、血糖、胆固醇和甘油三酯等血清生化指标均无显著差异；日粮1组的肉碱软脂酰基转移酶-I（CFT-I）含量显著高于日粮2组和日粮3组；日粮2组的肉碱软脂酰基转移酶-Ⅱ（CPT-Ⅱ）含量显著低于日粮1组和日粮3组；各组间淀粉酶、胃蛋白酶、脂肪酶活性及脂蛋白脂酶（LPL）和乙酰辅酶A羧化酶（ACC）含量均值无显著差异．表明日粮中添加多不饱和脂肪酸有利于刀鲚幼鱼的生长，缓沉饲料的利用效率最高，适合于刀鲚幼鱼驯养阶段使用．
英文摘要：
Effects of diets on growth, serum biochemical indices, and enzyme activities related to lipid metabolism in fingerlings Coilia nasus at age of 6 months were investigated during 60-day ex- periment in this study. Fingerlings with similar body length and mass were fed with one of 3 types of diets （diet 1 ： soft pellet; diet 2： soft pellet mixed with fish oil; diet 3： slow-sinking hard pellet）. Fish fed with diets 2 or 3 had significantly higher total body mass, rate of mass gain, specific growth rate, and fullness coefficient than those fed with diet 1. Fish fed with diet 3 exhibited the lower food coefficient compared to those fed with diets 1 or 2. Growth traits （length, length to mass ratio, length to width ratio, hepatopancreas somatic indices and viscera somatic index） and serum bio- chemical indices （total protein, albumin, blood glucose, cholesterol and triglycerides） in all three
