Production and Hatching Rate of Resting Egg of freshwater Rotifer, Brachionus calyciflorus Pallas fed the Different Diets

This study was performed to investigate production and hatching rate of the resting egg of freshwater rotifer, Brachionus calyciflorus fed the 5 different diets (ESP, freshwater Chlorella, baker's yeast, the mixture offfreshwater Chlorelia, and the mixture of baker's yeast and freshwater Chlorella). The highest productions of resting eggs were 123.3 egg/ml and 126.7 egg/ml in the mixture of ESP and freshwater Chlorella, and the mixture of baker's yeast and and freshwater Chlorella, respectively, which were significantly better than ESP, freshwater Chlorella or baker's yeast alone (P freshwater Chlorella was the highest, although this value was not significantly different compared with the mixture of baker's yeast and freshwater Chlorella, and freshwater Chlorella (P^lt;9.05). The results showed that the mixture of baker's yeast or ESP with the freshwater Chlorella seemed to be the best feeding regime for the production and hatching rate of resting egg of freshwater rotifer.
