Evaluación de la inclusión de harina de larva de mosca soldado (Hermetia illucens) en la dieta para juveniles del pez ángel (Pterophyllum scalare).

Abstract

The present research aimed to evaluate the effect of the inclusion of three (3) levels of soldier fly meal (0%, 20% and 40%) on the productive performance and survival of juvenile angelfish Pterophyllum scalare . Ninety P. scalare juveniles with an approximate average weight of 1.98 ± 0.7 g were used, which were fed three times a day for a period of 60 days. The fish were distributed in 9 aquariums of 28 liters of useful volume (10 fish per aquarium). A completely randomized design with three treatments and three repetitions was used, for a total of 9 experimental units. The productive variables evaluated were: WG weight gain (g), FC feed conversion (g / g), SGR specific growth rate (% / day) and survival percentage (%). The results of the experiment show that inclusions of soldier fly larvae meal of more than 20% in the diet negatively affect the productive performance and survival of the juveniles of the ornamental fish P. scalare.
