Effects of fish meal replacement by maggot meal in diets for Nile Tilapia fingerling (Oreochromis niloticus Linnaeus, 1758) in Burkina Faso

Résumé fourni par la source

In Burkina Faso, the availability of other local protein sources that can replace fishmeal in diets for Oreochromis niloticus is a concern of stakeholders involved in aquaculture sector. This study consisted of evaluating the growth performance of Oreochromis niloticus juveniles fed with diets containing maggot flour. It was conducted at Burkina Faso from April to June 2022. To test the effect of maggot flour on the growth of O. niloticus, 3 diets noted as R1, R2 and R3 were made of 100% fishmeal, 50% fishmeal + 50% maggot meal and 100% maggot meal respectively. These diets were used to feed 3 batches of juveniles (5 g) in duplicate group for 60 days. Each batch consisted of 15 fish per happa of 1 m2. After 60 days, results on zootechnical performances showed that juveniles of Oreochromis niloticus fed with diet 3 (36.70±9.32 g) had high growth performance compared to those fed with other diets (21.38 g±4.11 for diet 1 and 26.04 g±5.31 for diet 2). Statistically, the obtained results with diet 3 were found to be different from those obtained with diet 2 and different from those obtained with diet 1.
