Microalgae applications as aquaculture feeds

AP = abalone postlarvae BL = bivalve larvae BP = bivalve postlarvae BB = bivalve broodstock FZ MZ = marine zooplankton PL = penaeid shrimp larvae. 

Bivalves have a limited capacity to synthesize sterols de novo (Holden and Patterson, 1991) so dietary sterols from microalgae could be important in their nutrition. For post-larval P. magellanicus, the combination of C muelleri with Pavlova spp. produced higher growth rates than other algal diets tested, which was attributed to the comparatively high proportion of cholesterol in sterols from C. muelleri (Milke et al, 2008). Of the other 

Digestion efficiency of diatoms is an important determinant of their nutritional value for abalone post-larvae the former being a function of 

There are a number of plausible reasons explaining the positive effects of microalgae in green water systems, and in any particular example it may be a combination of these acting either independently or synergistically. These include (from Palmer et aL, 2007)
