Daily growth rates and feeding costs using condensed freshwater Chlorella for the production of 100 million rotifers for continuous, twice/day and once/day feedings were [61.1% and 1.47l], [45.7% and 2.28l] and [44.5% and 2.33l], respectively. We considered that the superior population growth in continuous feeding was due to the ability to maintaining the proper food density and dissolved oxygen levels.
