renewal with water at a constant rate of
7.5 mL/min and 12 light/12 dark photoperiod. To assess fish performance
a completely randomized design was established, with five
treatments (4 repetitions each) consisting of the addition of vitamin
E monophosphate at 0, 50, 100, 150 and 200 mg/kg of a base
diet composed of 36% crude protein and 3600 kcal of digestible energy/
kg. Treatments were initiated after a 5-day adaptation period
to the base diet.
