Artemia was incubated and then nutrient enrichment was conducted by the turbid liquid of biological flocculation(bio-floc) in the current experiment. The group using the artificial sea water was the control. We studied the survival, growth of Artemia nauplii in turbid liquid of bio-floc. The result was the survival of the group in bio-floc was higher than the control both on the fist day and the fifth day. the growth of the group in bio-floc was faster than the control both on the fist day and the fifth day, but on the third and fourth day was the opposite. Through the microscope, the intestinal contents of the group in floc significantly was more than the control group on the fifth day. That indicated Artemia can feed on floc or dissolved matter within the suspension. Biological floc is a kind of good food for Artemia. We analysed the aliphatic acid of Artemia nauplii, found that the eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) of Artemia nauplii in group using bio-floc were both higher than those of the control group. All showed that bio-floc can enrich Artemia nauplii.
