中文摘要:
      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影响仔蟹体内脂肪酸的百分含量。
英文摘要:
      Effects of dietary polyunsaturated fa tty acids , phospholipids on the survival and growth of Chinese cr ab , Er iocheir sinensis , f rom the megalopoa to the juvenile wer e studied using purif ied diets .The result shows that the sur vival of E .sinensis juvenile is gre atly incre ased by addit ion of the soybean phospholipids .But the sur vival to III juvenile is not significantly changed by only addit ion of the PUFA (C20∶5 +C22∶6 =58 . 5 %), except somewhat incre asing the sur vival from megalopa to the I juvenile .Mor eover , the composi tion of the unsatur ated f atty acids of the juvenile seems to vary significantly with the die tary level .
