 en Replacement of fish meal with maggot meal in African catfish ( Clarias gariepinus check for this species in other resources ) diets
Aniebo, Alphonsus Okey; Erondu, Ebere Samuel & Owen, Onyema Joseph

Abstract

Maggot meal produced from maggots grown on a mixture of cattle blood and wheat bran was used in substituting fish meal in African catfish, Clarias gariepinus, diet. A feeding trial was carried out for a period of ten weeks to evaluate the growth and nutrient utilization of catfish juveniles using diets in which fish meal was substituted with maggot meal at the following levels, 0, 50, and 100 %. Proximate and amino acid analyses of the maggot meal were carried out. Also the proximate composition of the test diets was determined. The results showed that maggot meal has 92.7% dry matter, 47.6% crude protein, 25.3% fat, 7.5% crude fiber, 6.25% ash, and an amino acid profile comparable to fish meal. Maggot meal-based diets compared favourably with fish meal-based diets as there were no significant differences in the growth and nutrient utilization indices (weight gain, length gain, daily growth rate, specific growth rate, feed conversion ratio and protein efficiency ratio). It is concluded that maggot meal is a viable alternative protein source to fish meal in the diet of African catfish. Its utilization is expected to reduce feed cost drastically, thus leading to a viable and sustainable aquaculture industry.

 es Sustitución de harina de pescado con harina de larvas en dietas para el bagre Africano ( Clarias gariepinus check for this species in other resources )
Aniebo, Alphonsus Okey; Erondu, Ebere Samuel & Owen, Onyema Joseph

Resumen

Se utilizó harina de larvas producida a partir de larvas cultivadas en una mezcla de sangre de ganado y afrecho de trigo en la sustitución de la harina de pescado en dietas pare el bagre Africano (Clarias gariepinus). Se realizó un ensayo de alimentación para investigar el eefcto de la harina de larvas sobre el crecimiento y la utilziación de alimento. Se formularon tres dietas las cuales contenían diferentes concentraciones de harina de larvas como sustituto de la harina de pescado (0, 50 y 100% nivel de sustitución). Después de un periodo de diez semanas, las dietas basadas en harina de larvas se compararon favorablemente con las dietas basadas en harina de pescado debido a que no hubo diferencias significativas en el crecimiento y los índices de utilización del alimento (ganancia de peso, incremento de longitud, tasa de crecimiento específica, relación de conversión de alimento y relación de eficiencia proteica). Se concluye que la harina de larvas es una fuente de proteínas viable y alternativa a la harina de pescado en la dieta del bagre Africano. Se espera que su utilización reduzca drásticamente el costo de alimentación, lo que conduciría a una industria acuicola viable y sustentable.

Palabras-clave
Harina de larvas, Clarias gariepinus, sustitución de harina de pescado.
