Abstract
Hypoxia (55% DO) and ascorbic acid (AA) supplementation level (0, 10, 25 and 50 mg AA equivalent kg—1 diet, supplied as ascorbyl polyphosphate) did not significantly alter juvenile sea bream Sparus aurata growth, body composition, survival and skin hydroxyproline concentration. Liver, head kidney and spleen AA concentrations significantly decreased with decreasing dietary AA level, but were not influenced by hypoxia. This study showed that sea bream AA requirements were not influenced by chronic hypoxic stress.
