| 摘 要： | 本文采用气相色谱分析法对海水鱼类育苗常用的4种饵料浮游动物的脂肪酸组成和含量进行了测定分析.结果表明卤虫无节幼虫、皱褶臂尾轮虫、蒙古裸腹溞和太平洋纺锤水蚤的粗脂肪含量分别占其体重的21.54％、9.70％、6.67％和4.66％.单不饱和脂肪酸的含量排序分别为蒙古裸腹溞＞纺锤水蚤＞轮虫＞卤虫；多不饱和脂肪酸含量则为卤虫＞裸腹溞＞轮虫＞纺锤水蚤.此外，太平洋纺锤水蚤尚含有C226(DHA)高不饱和脂肪酸，这在其它饵料生物中并未检出.卤虫无节幼虫和褶皱臂尾轮虫的脂肪酸组成中，油酸(C181)、亚油酸(C182)和亚麻酸(C183)占有较大比例，而二十碳以上的不饱和脂肪酸含量很低.文中讨论了脂肪酸组成和含量与营养效果的关系.

| Abstract: | Fatty acid composition and contents in 4 kinds of planktonic food animals were measured quantitatively by means of gas chromatographic technique. The coarse fat occupied their body weight (wet weight) in nauplii of Artemia salina (cysts from Great Salt Lake, USA),Brachionus plicatilis (Rotifer), Moina mongonica (Cladocera) and Acartia paci fica (Copepod)were 21.54, 9.7, 6.67 and 4.66%, respectively. The total mono-unsatisfied fatty acid (TMUFA) ranks in descent sequence of M. mongonica, A. pacifica , B. plicatilis, Ar. salina, and total poly-unsatified fatty acid (TPUFA) Ar. salina, M. mongonica, B. plicatilis and A.pacifica. DHA (C22:6) was detected only in A. pacifica samples. There were greater propotion of C18: 1, C18:2 and C18:3 in Ar. salina and B. plicatilis samples comparative to A. pacifica and M. mongonica, but the contents of unsatisfied fatty acid which carbon number is more than 20 were scarce. The relationship between contents of fatty acid and nutrient effect on the health and survivorship of marine fry culture was discussed in this paper. |
