AA30, AA90, and AA300 were 30, 90, and 300 mg/kg of ascorbic acid incorporated diet groups and CBP30, CBP90, and CBP300 were citrus by-products incorporated diets replacing ascorbic acid levels in the AA diets.
Values are means from triplicate groups of fish.
Final body weight (g).
Feed conversion ratio: Dry feed fed / Wet weight gain.
Protein efficiency ratio: Wet weight gain / Total protein given.
Pooled standard error of the mean.
AA, ascorbic acid; CBP, citrus by-product.
