Abstract
Este estudio muestra los antecedentes del cultivo larvario del puye, Galaxias maculatus (Jenyns), un pequeño pez de aguas frías del hemisferio sur. Para el cultivo, larvas recién eclosionadas fueron puestas en estanques de 500 litros de volumen útil. Las larvas fueron alimentadas utilizando una secuencia de
rotíferos, Arfemia spp. y alimento inerte. Durante todo el sistema de producción que duró 150 días, fue necesario realizar un desdoble y una separación por tamaño. Los resultados muestran que esta especie puede alcanzar su tamaño comercial (4 a 6 cm) en seis meses aproximadamente, si es cultivado en un
sistema intensivo como el propuesto. Los resultados muestran que las larvas de Galaxias maculatus, responden satisfactoriamente a la secuencia de alimentación que incluye rotiferos, Arfemia spp. y alimento inerte, en un sistema intensivo de producción como el estudiado.
This study reports data on the larval culture of the "puye", Galaxies maculatus (Jenyns), a small cold water fish occurring in the Southern Hemisphere. For this culture, recently enclosed larvae were placed into 500 liter tanks and fed first with rotifers, then with Artemia spp., and finally with prepared feed. Over the growth period of 150 days, several separations of the fishes were necessary based on size differentials. Results suggested this species would reach a commercial size of 4 to 6 cm in about six months using the intensive system proposed. The larvae of this fish responded well to the feeding sequence described, within the intensive culture system studied.
