The nutritional value, astaxanthin level and population growth of Moina macrocopa fed with Chlorella sp., Saccharomyces cerevisiae and Phaffia rhodozyma in eight treatments ( C1: 1 x 10(5) cells/ml; C2: 1 x 10(6) cells/ml; S1: 4 x 10(6) cells/ml; S2: 4 x 10(7) cells/ml; P1: 4 x 10(7) cells/ml; P2: 4 x 10(8) cells/ml; SP1: S + P 4 x 10(6) : 4 x 10(7) cells/ml;and SP2: S + P 4 x 10(6) : 4 x 10(8) cells/ml) were examined. The results showed that lipid content was significantly different among the treatments but protein and carbohydrate were not. C2 had the highest lipid content ( 11.83 +/- 0.87%) whereas C1 and SP1 had the highest protein ( 76.26 +/- 2.84%) and carbohydrate ( 14.56 +/- 3.04%), respectively. In addition, SP1 had the highest astaxanthin level ( 0.83 +/- 0.19 mu g/g) and S1 showed fastest population growth rate ( 0.81 day(-1)). This indicated that feeding on S. cerevisiae resulted in high lipid and astaxanthin levels and a concentration of 4 x 10(6) cells/ml enhanced the population growth of M. macrocopa. Therefore, it could replace or be used as supplementary to Chlorella sp. for cladoceran production in mass cultures.
