Resumen
El alto crecimiento productivo del sector acuícola, ha provocado una gran presión en la búsqueda de materias primas alternas a la harina de pescado por ingredientes con igual o mejor calidad nutricional. Los insectos, en especial las larvas de mosca soldado negro (MSN), Hermetia Illucens se considera una fuente de proteína animal idónea para la alimentación de especies acuícolas, por su evidencia del perfil nutricional. El presente trabajo evaluó el efecto de la inclusión de harina de H. illucens sobre el crecimiento de Oreochromis sp., posterior, se utilizaron tres dietas experimentales: control (100% HS; 0% MSN), T1 (75% HS; 25% MSN) y T2 (50% HS; 50% MSN) durante 90 días con porcentaje proteico (26,6 y 29,7 %) para el T1 y T2. Los resultados de los parámetros productivos mostraron una supervivencia, factor de conversión alimenticia y tasa de crecimiento para el Control (80%, 2,9g y 1,9 %/día), Tratamiento 1 (100%, 2,6g y 2,1 %/día) y Tratamiento 2 (93%, 2,7g y 1,8 %/día), sin evidenciar diferencias significativas (p>0,05). El T1 fue el tratamiento que mostró mejores resultados en comparación con los demás tratamientos, obteniendo un crecimiento alométrico positivo para todos los organismos. Por lo que la dieta de harina de H. illucens puede considerarse como alternativa proteica en inclusiones hasta 25% en juveniles de Oreochromis sp.
The high productive growth of the aquaculture sector has caused great pressure in the search for alternative raw materials to fishmeal for ingredients with equal or better nutritional quality. Insects, especially the larvae of the black soldier fly (MSN), Hermetia Illucens, are considered an ideal source of animal protein for feeding aquaculture species, due to their evidence of the nutritional profile. The present work evaluated the effect of the inclusion of H. illucens flour on the growth of Oreochromis sp., subsequently, three experimental diets were used: control (100% HS; 0% MSN), T1 (75% HS; 25% MSN) and T2 (50% HS; 50% MSN) for 90 days with protein percentage (26.6 and 29.7%) for T1 and T2. The results of the productive parameters showed survival, feed conversion factor and growth rate for Control (80%, 2.9g and 1.9%/day), Treatment 1 (100%, 2.6g and 2.1 %/day) and Treatment 2 (93%, 2.7g and 1.8%/day), without showing significant differences (p>0.05). T1 was the treatment that showed the best results compared to the other treatments, obtaining positive allometric growth for all organisms. Therefore, the H. illucens meal diet can be considered as a protein alternative in inclusions up to 25% in juveniles of Oreochromis sp.
