摘　　要：以两株海洋酵母 (Saccharomycessp 和Rhodotorulasp )培养褶皱臂尾轮虫 (Brachionusplicatilis) ,测定其脂肪酸组成。结果表明 :轮虫具有一定的合成高度不饱和脂肪酸 (HUFA)的能力 ,但其体内HUFA含量不足1% ,仍需用富含HUFA的饵料强化 ,才能满足海水仔稚鱼对HUFA的需要。The fatty acids composition of rotifers (Brachionus plicatilis) fed marine yeast (Saccharomyces sp.& Rhodotorula sp.)was investigated.The results indicate that the fatty acids composition of rotifers closely relate to that of diets.Rotifers are capable of synthesizing some highly unsaturated fatty acids (HUFA),but the rate of synthesis of these fatty acids is rather low.Although HUFA content of rotifers fed marine yeast is higher than rotifers fed bakers yeast,the level(less than 1%)is insufficient to meet the possible demand of marine fish larvae.Hence,rotifers fed marine yeast must be enrich with HUFA-rich food.
