The use of microalgae as live food for the nutrition of 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; In mariculture, microalgae directly support all stages of growth of bivalves and fish or indirectly are fed to brine shrimp or rotifers, which are then fed to subsequent larval/juvenile stages of crustaceans and fish larvae providing essential nutrients and other growth-promoting factors (Cho et al., 1999). nutrients of the microalgae offered for feeding aquatic animals are crucial especially during the larval stages, as well as their rapid growth speed and their adequate size for ingestion (Marrone, et al., 1997). al. (2005) stated 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...
