Resumen
En la actualidad, uno de los desafíos más importantes en la acuicultura son los costos de producción, siendo el alimento balanceado el factor más determinante de los gastos operacionales. En Ecuador, el cultivo de chame (Dormitator latifrons) constituye una opción acuícola llamativa para diversificar la producción local debido a su bajo costo de cultivo y rol ecológico importante. En este estudio se evaluó el efecto de sistemas biofloc en un cultivo de juveniles de chame determinando parámetros fisicoquímicos y zootécnicos tales como ganancia de peso (GP), longitud promedio (cm), tasa de crecimiento específico (TCE), tasa de supervivencia y conversión alimenticia (CA). Los resultados mostraron que el sistema biofloc, utilizado como fuente de alimento suplementario, mejoró significativamente el crecimiento de los juveniles de chame (GP: 4,10±0,10a; CA: 1,77±0,14a) en comparación con un cultivo tradicional con recambios de agua diarios.
Currently, one of the most important challenges in aquaculture is production costs, with balanced feed being the most determining factor in operational expenses. In Ecuador, the cultivation of chame (Dormitator latifrons) constitutes a striking aquaculture option to diversify local production due to its low cultivation cost and important ecological role. In this study, the effect of biofloc systems on a culture of chame juveniles was evaluated by determining physicochemical and zootechnical parameters such as weight gain (GP), average length (cm), specific growth rate (TCE), survival and conversion rate. food (CA). The results showed that the biofloc system, used as a supplementary food source, significantly improved the growth of chame juveniles (GP: 4.10±0.10a; CA: 1.77±0.14a) compared to a culture traditional with daily water changes.
