摘　　要：主要探索不同饲料组成对鱼体组成的影响。将360尾南方鲇（Silurus meridionalis Chen）幼鱼随机分成24组，饲养于24个水泥池中；共设计了21种饲料；实验持续了40d。结果表明：（1）不同营养素水平，对鱼体中的蛋白质沉积无明显影响；肌肉中脂肪水平随着饲料中脂肪和碳水化合物（CBH）水平的增加而增加；CBH含量为33％时，肌肉中的CBH的沉积量显著高于其他几个组（P〈0．05）；（2）脏体比和肠脂比随着饲料中脂肪水平升高而升高，脂肪水平9％～15％，肝脏中沉积的脂肪含量随着饲料中脂肪含量的增加而增加，添加CBH含量为33％的饲料时，肝脏中糖原的沉积含量显著的高于其他几个CBH含量的组（P〈0．05）。360 southern catfish （Silurus meridionalis chen） juvenile were randomly divided into 24 groups and distributed to 24 cement pits. And 21 diets were designed in this test. The feeding test lasted for 40 days. This study was to determine effects of artificial diets on the body composition of southern catfish juveniles. These results clearly showed： （1）There were not affected by nutrients at different levels; The lipid in muscle increased with increasing dietaly lipid level and carbohydrate; At carbohydrate 33% , the carbohydrate inclusion in muscle were higher than other groups （P 〈 0.05）. （2）RBB and FWB increased with increasing dietary, lipid level, at lipid 9% - 15%, the lipid in liver increased with increasing dietary lipid level; At carbohydrate 33% , the carbohydrate inclusion in liver were higher than other groups（P 〈 0. 05）.
