The use of microalgae as a living food for feeding aquatic organisms is well documented by several researchers (Cho et al., 1999; Zhu, et al ., 1997; Luyen et al., 2007; Rivero-Rodríguez et al., 2007; Duerr et al., 1998; or are indirectly fed to brine shrimp or rotifers, which are then fed to later larval/juvenile stages of crustacean and fish larvae by providing essential nutrients and other growth-promoting factors (Cho et al., 1999). Therefore, the nutritional property of microalgae proposed to feed aquatic animals is crucial, especially during larval stages, as well as their rapid growth rate and suitable size for ingestion (Brown, et al., 1997). De Castro Araújo, et al. (2005) mentioned that the growth rate or biomass and biochemical composition of microalgae are two important characteristics that evaluate the potential of a species to be used for aquaculture purposes. For these reasons, several studies...
