Alimento vivo como alternativa en la dieta de larvas y juveniles de Pterophyllum scalare (Lichtenstein, 1823)

Abstract

La nutrición en los estadios iniciales de los peces constituye uno de los principales problemas de cultivo, debido a que es la etapa en la que se presenta la mayor mortalidad. En el presente estudio se evaluó, como alternativa en la alimentación de larvas y juveniles de Pterophyllum scalare, el efecto de tres alimentos vivos (Moina wierzejski, Artemia franciscana y Panagrellus redivivus) y un alimento comercial (Aquarian Tropical Flakes) sobre la tasa específica de crecimiento (TEC) y la sobrevivencia. La TEC de larvas resultó más alta con nauplios de A. franciscana (17.57 ± 0.39a% peso corporal ganado mg/ día), seguida de M. wierzejski (16.63 ± 0.41b), P. redivivus (14.25 ± 0.42c) y del alimento comercial (13.20 ± 0.42d) (P<0.05). En los juveniles, la TEC fue mayor con M. wierzejski (6.28 ± 0.21a% peso corporal ganado mg/día), seguida de A. franciscana (6.04 ± 0.23b), P. redivivus (4.86 ± 0.23c) y del alimento comercial (4.39 ± 0.23d) (P<0.05). La sobrevivencia de las larvas fue 80.00 ± 10.00a% con A. franciscana y M. wierzejski, mayor 25 y 40.62% con respecto a P. redivivus (60.00 ± 10.00b%) y al alimento comercial (45.00 ± 10.00b%) (P<0.05). En los juveniles, la sobrevivencia del 100% no difirió con ningún alimento. Finalmente, los nauplios de Artemia en la etapa larval y la Moina en juveniles estimularon favorablemente la TEC y la sobrevivencia de P. scalare.
