分别以纯酵母和鱼油酵母培养的蒙古裸腹溞及卤虫无节幼体投喂河蟹溞状幼体,探讨了不同食物条件对蒙古裸腹溞及河蟹幼体的脂类和脂肪酸组成的影响.结果表明:鱼油酵母组蒙古裸腹溞总脂含量达16. 2% (占干重),接近卤虫无节幼体的19. 9%,但EPA含量仍远较其低.用经鱼油酵母培养的蒙古裸腹溞投喂河蟹幼体,从Z3 -M变态率和成活率分别为17%和12. 5%,比纯酵母组高1倍多,表明用鱼油强化蒙古裸腹溞培养河蟹幼体,对河蟹幼体发育和存活有明显的促进作用.
The effects of different dietary conditions on the lipid and fatty acid composition of M. mongolica and C. latifolia were studied by feeding M. nudibranch and Artemia nauplii with pure yeast and fish oil yeast respectively.The results showed that: Fish oil yeast group Mongolia naked belly fat total lipid content of 16.2% (accounting for dry weight), close to Artemia nauplii 19.9%, but the EPA content is still far lower.Using fish oil yeast cultured Mongolia nude Abdominal canthal feeding crab larvae, Z3-M metamorphosis rate and survival rate were 17% and 12.5%, respectively, compared with pure yeast group more than doubled, indicating that the use of fish oil to strengthen the Mongolian mongodian grub training crab larvae, crab larvae Development and survival have a significant role in promoting.
