Rotifers are widely used as a live prey for finfish larvae, although their content in minerals such selenium and zinc is lower than fish. In the present study, mixed microalgae (i.e., Isochrysis aff. galbana Nannochloropsis oculata) were enriched with different amounts of Se Zn either alone (45, 90, 135 mg L−1 Zn, 60, 120, 180 Se) or (22.5, 45, 90 30, 120 L−1). The was analysed after 1 3 h enri...
