Abstract: Since sudden mortalities and increased skeletal deformities in gilthead seabream juveniles are currently found in production hatcheries, this study aimed to evaluate the contribution of essential fatty acids, particularly DHA over early feed quality, larval growth, survival and the apparition of skeleton abnormalities in highly commercial interest specie such as Sparus aurata. Sea bream larvae were reared under intensive conditions and fed rotifers enriched with two different enrichment emulsions differing in DHA content. Thus, essential fatty acid composition of rotifers, showed fatty acid profile of enrichment emulsions. The increase in rotifers DHA (10.0 to 25.4% TFA) were also reflected in a higher DHA content in the FA composition of larval fed this rotifers (13.0 to 20.4% TFA) when these preys were the main source of food (14dah). Survival at 50 days after hatching (13.9±4.3) and growth evolution from 3dah until day 50, were similar in both treatments, whereas bone malformations, particularly opercula reduction, and jaw deformities were higher in higher DHA rotifers fed larvae.
