Abstract
    Although information on bivalve nutrition is still very scarce, several studies have demonstrated the importance of lipids, in particular triglycerides, as a source of energy and essential fatty acids in the early life stages. Experimental diets used so far to study bivalve nutrition either heavily pollute the water or are too complex to prepare in a hatchery. The potential use of lipid emulsions as off-the-shelf supplements was evaluated through the analytical verification of the ingestion and incorporation of n-3 highly unsaturated fatty acids (HUFA) by the juvenile sea scallop Placopecten magellanicus fed lipid emulsions of different fatty acid composition as a supplement to Isochrysis sp. (clone T-Iso). The average lipid content on the scallops fed the lipid supplements was 20% higher compared to that in the control fed algae only (3.29 ± 0.16 versus 2.75% of dry weight, respectively). Changes in the fatty acid composition, in particular of n-3 HUFA, were demonstrated in total lipids, polar lipids, and triglycerides of juvenile sea scallops supplemented with lipid emulsions on the basis of ethyl ester concentrates of n-3 HUFA and were dependent on the level and proportion of 20:5n-3 and 22:6n-3 present in the emulsion. The effective incorporation of essential fatty acids from lipid emulsions indicated that the supplementation of lipid emulsions to live algae may improve and standardize the dietary supply of lipids and fatty acids in hatchery production of bivalves.
