Abstract

The objective of this work was to evaluate the effect of feed training periods on the productive performance and survivorship of pirarucu juveniles (Arapaima gigas), during the transition from ground fish mass diet to a dry-feed diet. Animals with 15.8±1.2 g were evaluated with gradual substitutions of the diet at every 2, 3, 4, and 5 days. After 12 days from feed training, the substitutions at every two and three days provided the highest specific growth rates. The replacement of diet based on forage fish by dry formulated diet may be done every two or three days.
