Abstract The objective of this study was to evaluate the properties of garlic as a growth promoter in larvae of angelfish Pterophyllum scalare and its benefits during transport of juveniles of this species. The experiment was conducted in recirculation aquaculture system, consisting of 20 tanks of 40 L equipped with independent water input and output. We used 1,400 larvae distributed among five treatments, with four repetitions, which totaled 20 experimental units. The treatments were 0, 50, 100, 200, and 400 mg of garlic extract per kilo of feed. The results showed that the inclusion of levels of garlic extract in the feed did not significantly effect the fish's development or their transport. Neither did the inclusion of levels of garlic extract affect the survival of the larvae during the trial period. New research with extracts of higher dosages should be performed to elucidate the effect of garlic extract as a growth promoter.
Resumo O estudo teve como objetivo avaliar as propriedades do alho como promotor de crescimento em larvas de acará bandeira Pterophyllum scalare e seus benefícios no transporte de juvenis da mesma espécie. O experimento foi conduzido em sistema de recirculação composto por 20 aquários de 40 L de volume útil, dotado de entrada e saída de água independentes e teve a duração de 40 dias. O delineamento experimental adotado foi o inteiramente casualizado (DIC), com cinco tratamentos e quatro repetições, totalizando 20 unidades experimentais. Foram utilizadas 1.400 larvas de acará bandeira (Pterophyllum scalare) divididas entre os tratamentos.
