Note: Means ± SD within the same row with different superscripts are significantly different (p< 0.05). Different superscript letters (a, b, c, d) indicate significant differences between different groups: CG, the fish received basal diet; Syrena Boost group 1 (SB1), fish received basal diet containing 0.1 g kg–1 Syrena Boost; Syrena Boost group 2 (SB2), fish received basal diet containing 0.2 g kg–1 Syrena Boost; Syrena Boost group 3 (SB3), fish received basal diet containing 0.4 g kg–1 Syrena Boost.

CAT = catalase; MDA = malonaldehyde; SOD =, superoxide dismutase.
