Gill NKA activity (A), intestinal NKA activity (B), and intestinal HA activity (C) in S. aurata juveniles fed with different experimental diets (CT, control; D₁, 1 mg-; and D₂, 2 mg AFB1 kg⁻¹ fish feed) for 85 days. Data are presented as mean ± SEM (n = 6–10). Different letters indicate significant differences among the same intestinal regions.
