This study assessed recovery of alpha‐lipoic acid (α‐LA) on antioxidant capacity of blunt snout bream ( Megalobrama amblycephala ) juveniles after ammonia stress. Around 270 healthy juveniles (13.7 ± 1.6 g) were separated into three groups and exposed to ammonium chloride solutions at 0 (G1), 5.45 (G2), and 10.89 mg/L (G3). Ammonia stress lasted for 72 h, then all fish were transferred to aerated tap water for the recovery exp...
