The preliminary experiment consisted of determining the concentration of riboflavin added to T. suecica cultures to achieve a maximum quantity of this vitamin in the microalgal cells. Seven concentrations were tested in triplicate: 0 (control), 2.5, 5, 10, 20, 40 and 80 ng ml− 1; the results showed that the 10 ng ml− 1 was the optimum concentration that the microalgae accumulated 4.29 ± 0.19 pg cell− 1, 21.2 ± 0.35 ng ml− 1 and 19.4 ± 0.56 μg g− 1 (dry weight) of riboflavin. Control and enriched microalgal cultures were used for feeding the rotifer B. plicatilis. Control and enriched rotifers were used for feeding white sea bream and gilthead sea bream larvae. Rotifers fed on enriched microalgal cultures accumulated significantly (P < 0.05) more riboflavin than those fed the control culture after 24 h of enrichment (17.7 ± 1.3 and 13.7 ± 1.2 μg g− 1 (dw), respectively) and after 24 h of starvation (10.2 ± 44 1.1 and 5.6 ± 0.4 μg g− 1 (dw), respectively). In both species of sparids, those larvae fed enriched rotifers contained significantly more riboflavin than those fed control rotifers, the vitamin B2 content in control and enriched white sea bream larvae was 21.7 ± 2.7 and 29.2 ± 1.3 μg g− 1 (dw), respectively, and in control and enriched gilthead sea bream larvae it was 5.5 ± 1.0 and 7.3 ± 0.05 μg g− 1 (dw), respectively. Significant differences in length and survival of white sea bream larvae were observed. In the present study, riboflavin enrichment of microalgal cultures resulted in higher levels of this vitamin in both rotifers and fish larvae.
