摘要
比较不同食物和不同处理方式培养的蒙古裸腹（Ｍｏｉｎａｍｏｎｇｏｌｉｃａ）脂肪酸组成，ＥＰＡ含量在用海水小球藻全培养时为２７．６％，用２种面包酵母培养的分别为５．６％和１０．７％，用鱼油强化的为７．４％和１０．５％。试验表明蒙古裸腹难以同化吸收食物中的ＤＨＡ，但在鱼油强化时其肠道中储存的油粒可含一定量的ＤＨＡ，因此可用ＤＨＡ含量高的鱼油短时间强化，以肠道为ＤＨＡ载体，来满足海水鱼苗的营养要求。
The compositions of fatty acid in total lipids of Moina mongolica cultured with different food and treated by different way were compared. The M.mongolica were respectively cultured with Chlorella spp. thoroughly, 2 kinds of yeast, and fish oil. Their contents of EPA were 27.6%, 5.6% and 10.7%, 7.4% and 10.5%, respectively. The results show that M.mongolica can hardly absorb DHA in food, but there are some DHA in the oil particles laid in the intestine of M.mongolica when it is enriched with fish oil. So M.mongolica can be enriched with fish oil of high-containing DHA in a short time when the intestine acts as a carrier of DHA. That can meet the nutrient requirement of fish fry in the sea.
