Juveniles of tambaqui Colossoma macropomum were fed diets containing 0, 100 and 500 mg of L‐ascorbic acid (AA) per kg of feed for 10 weeks. Subsequently exposed to acute hypoxia for 6 h, the animals fed with high levels of AA exhibited no changes in blood pH and plasma glucose and reduced levels of lipid peroxidation. Thus, AA‐enriched diets reduce the effects of hypoxia insult on juveniles of C. macropomum .
