High Density Cultivation of Rotifer, Brachionus rotundiformis in the Different Diets

The experiment was carried out in a 10 vessel in order to evaluate the growth and nutritional quality of rotifer, Brachienus rotundiformis fed by different diets (Freshwater Chlorella, Marine Chlorella and -yeast) for the high density cultivation. The maximum densities for the rotifer fed on the marine Chlorella, freshwater Chlorella and -yeast were and 2,3902,750 inds./ml, respectively. Therefore, the maximum densities for the rotifer fed on the marine Chlorella and freshwater Chlorella were higher than that for rotifer fed on the -yeast The essential n-3 highly unsaturated fatty acid in rotifer fed on the marine Chlorella was which was slightly lower than that in rotifer fed on the -yeast, , while it was higher than that in the rotifer fed on freshwater Chlorella, . This result indicated that marine Chlorella could be appropriate diet for the high density cultivation of rotifer.
