An experiment was run to evaluate three feeding methods for pejerrey fingerlings, in a complete randomized design with four replications. Each experimental unit consisted of a 20L aquarium and 20 three days old fingerlings. For six weeks, three times a day, fish received the following diets: T1= mash diet; T2= mash diet + zooplankton; T3= zooplankton. Results showed that zooplankton promotes better fingerlings growth and survival. Fish fed with mash diet showed significantly lower growth and survival, but acceptable considering actual status of nutrition studies for pejerrey.
