Abstract

En la presente investigación se evaluó el efecto de la relación carbono/nitrógeno (C:N), la calidad del agua, la productividad y la composición proximal de alevines de Oreochromis niloticus durante 58 dí­­as de cultivo. El diseí­±o experimental consistió de cuatro tratamientos: un sistema convencional (control) y tres sistemas biofloc (CN10, CN15 y CN20). Se utilizaron 12 unidades experimentales de 0.04 m3 con 30 peces (750 pez m-3) con peso promedio individual de 1.55 ± 0.01 g. Se constató la existencia de interacción entre los parámetros de calidad de agua del sistema biofloc y los parámetros productivos de los alevines de tilapia. El tratamiento CN10 presentó una baja producción de sólidos sedimentables: 38.61 ± 0.54 mL L-1 (p<0.05), hecho que contribuyó con el rápido crecimiento de los individuos (21.7 ± 2.18 g), alcanzando rendimientos finales promedios de 15.50 ± 0.81 kg m-3 (p<0.05). Es posible concluir que el cultivo de alevinos de O. niloticus en sistema biofloc, con una relación C:N de 10, presentó el mejor rendimiento de producción si comparado con los otros tratamientos (CN15 y CN20).
