中文摘要:
      分别以经海水小球藻、牟氏角毛藻和50DE-G强化剂强化的轮虫投喂中华绒螯蟹早期幼体,至Zao状Ⅲ期后改喂卤虫无节幼体,探讨了饵料ω-3系列高度不饱和脂肪酸对幼体发育和存活的影响。结果表明:小球藻轮虫组的幼体发育至第Ⅰ期幼蟹的存活率最高,为12.00%,强化剂轮虫组和角毛藻轮虫组次之,分别为10.67%和9.67%,而酵母轮虫组最低,仅为3.67%;结合分析Zao状Ⅴ期幼体脂肪酸组成可知,幼体发育至第Ⅰ期幼蟹的存活率与其总脂含量和ω-3HUFA含量密切相关,而Zao状Ⅴ期幼体总脂含量与ω-3HUFA含量随饵料轮虫总脂和ω-3HUFA含量的增加而提高,表明早期幼体所摄取的ω-3HUFA对后期幼体发育和存活有明显的促进作用。
英文摘要:
      Effects of ....3 series highly unsaturated fatty acids( ....3HUFA) on the development and survival of Chinese mitten..hand crab larvae, were studied by feeding with rot ifers enriched with two kinds of marine unicellular algae and the enrichment 50DE..G at early developmental stages and Artemia nauplii during postlarval developmental stages. The crab larvae obtained highest survival rate, 12. 00%, after fed with the rotifer treated with Chlorella, and then two groups treated with 50DE..G and Chaetoceros muelleri , 10. 67% and 9. 67% respectively, while the control group treated with baker.. s yeast is the lowest one, 3. 67%. The survival rate increased w ith increasing of the content of total lipid and ....3HUFA in the crab larvae, and the relative percentage content of ....3HUFA ( mainly eicosapentaenoic acid, EPA and docosahexaenoic acid, DHA) in the crab larvae may be affected by the content of ....3HUFA in its diets. The results suggest that EPA and DHA absorbed at the early developmental stages can influence the development and survival of the crab postlarvae.
