Changes in hematological parameters, plasma cortisol, and acetylcholinesterase of juvenile rockfish, Sebastes schlegelii supplemented with the dietary ascorbic acid

open access: yesAquaculture Reports, 2016
Juvenile rockfish (mean length 13.6 ± 1.4 cm, and mean weight 53.6 ± 4.2 g) were fed diets containing different levels of ascorbic acid (0, 50, 100, 200, and 400 mg/kg) for 4 weeks. Fish were fed twice daily (08:30 and 18:30).
