Effects of dietary copper on growth, antioxidant capacity and immune responses of juvenile blunt snout bream (Megalobrama amblycephala) as evidenced by pathological examination

The goal of this study was to investigate the effects of dietary Cu on growth, antioxidant capacity and immune responses in juvenile blunt snout bream with histological examination. Fish were fed three practical diets containing graded copper levels ranging from 1.43 mg/kg-9.13 mg/kg for 10 weeks. The control diet (1.43 mg/kg) significantly improved the growth performance of blunt snout bream (P < 0.05). The 5.21 mg/kg dietary copper...
