摘　　要：用精制饲料添加一定量的磷脂和多不饱和脂肪酸，饲喂中华绒螯蟹大眼幼体并育成Ⅲ期仔蟹。结果表明：饲料中添加一定量的磷脂对提高大眼幼体育成仔蟹的成活率有较显著的作用，而添加多不饱和脂肪酸对提高大眼幼体到Ⅲ期仔蟹的成活率的作用不显著，但可显著地提高大眼幼体到Ｉ期仔蟹的成活率。另外，饲料中的不饱和脂肪酸含量可显著地影响仔蟹体内脂肪酸的百分含量。Effects of dietary polyunsaturated fatty acids, phospholipids on the survival and growth of Chinese crab, Eriocheir sinensis, from the megalopoa to the juvenile were studied using purified diets. The result shows that the survival of E. sinensis juvenile is greatly increased by addition of the soybean phospholipids. But the survival to III juvenile is not significantly changed by only addition of the PUFA (C20∶5+C22∶6=58.5%), except somewhat increasing the survival from megalopa to the I juvenile. Moreover, the composition of the unsaturated fatty acids of the juvenile seems to vary significantly with the dietary level.
