Rotifer (Brachionus plicatilis) culture in batch system with suspension of algae (Nannochloropsis oculata) and bakery yeast (Saccharomyces cerevisiae

Abstract
The rotifer Brachionus plicatilis is commonly cultured and used in hatcheries as the first feed of marine and fresh water fish larvae. Several cultivation techniques have been developed and applied in hatcheries by aquaculture researchers. In this study, we evaluated the nutritional effect on Brachionus plicatilis population growth; rotifer was cultured on suspension of algae (Nannochloropsis oculata) and yeast (Saccharomyces cerevisiae) in batch culture system. Rotifers that fed with yeast (T2) developed well at the beginning but with increasing of rotifers biomass environment was polluted and after period of time mass mortality observed. Overall, in this case (T2) the biomass production was low. The rotifers that fed with algae (T1) had same population increasing and there was no significant difference between use of yeast and algae. The best growth rate was related to control treatment (C) that feed with blend of algae and bakery yeast. The lowest growth rate was observed in T1 and T2 treatments that fed just with algae and bakery yeast separately.
