摘　　要：研究了在悬浮式生物反应器中利用养殖固体废弃物产生的细菌悬浊液孵化卤虫的效果。结果表明,利用生物絮凝体悬浊液孵化卤虫的存活率均高于人工海水孵化组,且卤虫个体长度(953.41±55.64)μm大于人工海水孵化组的卤虫个体长度(916.31±73.43)μm。生物絮凝体悬浊液孵化的卤虫的二十碳五烯酸(EPA)和二十二碳六烯酸(DHA)含量分别为(12.00%±1.28%)和(1.72%±0.07%),均高于人工海水孵化的卤虫。本研究认为,利用养殖固体废弃物生产的生物絮凝体可以用来营养强化卤虫。Artemia was incubated and then nutrient enrichment was conducted by the turbid liquid ofbiological floeculation（bio-floc） in the current experiment. The group using the artificial sea water was thecontrol. We studied the survival, growth of Artemia nauplii in turbid liquid of bio-floc. The result was thesurvival of the group in bio-floc was higher than the control both on the fist day and the fifth day. the growthof the group in bio-floc was faster than the control both on the fist day and the fifth day, but on the third andfourth day was the opposite. Through the microscope, the intestinal contents of the group in floc significantlywas more than the control group on the fifth day. That indicated Artemia can feed on floe or dissolved matterwithin the suspension. Biological floc is a kind of good food for Artemia. We analysed the aliphatic acid ofArtemia nauplii, found that the eicosapentaenoic acid （EPA） and docosahexaenoic acid （DHA） of Artemianauplii in group using bio-floc were both higher than those of the control group. All showed that bio-floc canenrich Artemia nauplii.
