“…Non‐enzymatic compounds, such as vitamin C and E, are also powerful antioxidants (Ai et al, ; Betancor et al, ; Gao, Koshio, Ishikawa, Yokoyama, & Edward, ; Montero et al, ). In this sense, high concentrations of vitamin C and E have been detected in fish eggs indicating the importance of these micronutrients during fish early development (Hemre, Mangor‐Jensen, & Lie, ; Lie, Sandvin, & Waagbø, ; Mukhopadhyay, Chattopadhyay, & Mitra, ; Skřivan, Marounek, Englmaierová, & Skřivanová, ). The requirements for vitamins C and E given by NRC () for fish are 30 and 25–120 mg/kg respectively but the supplementation with extra dosage of both vitamins has proved to reduce mortality, oxidative stress as well as to improve growth in fish larvae (Kolkovski et al, ; Merchie, Lavens, & Sorgeloos, ; Stéphan, Guillaume, & Lamour, ).…”
