Rotifers may be so numerous that in spite of their small size they represent a significant portion of total zooplankton biomass; and they are an important link between the microbial loop and higher trophic levels. Rotifers lack the ability to elongate shorter chain fatty acids and, therefore, must be enriched to satisfy the HUFA requirement before they are fed to marine fish larvae (Sargent et al. The microalga Nannochloropsis oculata is used as a diet for rotifers and can enrich the highly unsaturated fatty acid (HUFA) proportion of rotifer polar lipids (PL-HUFA). Fish. The first experiment demonstrated that larvae initially fed at 30 hph exhibited a significantly higher survival rate (24%) than larvae initially fed at 36, 42, and 48 hph (19%, 16%, and 16%), respectively.
