Comparative Study of Three Locally Available feeds on the Growth and Nutritional Quality of Oreochromis niloticus Juveniles

The aim of the present study was to evaluate the effects of three feeds formulated for three fish farming agroecological areas of Cote d’Ivoire on the growth and nutritional quality of Oreochromis niloticus juveniles. Feeds were formulated at 30% crude protein with locally-sourced raw materials available by area. The use of different ingredients at different levels for feeds formulation made variations in the nutritional compositions and costs of the three feeds produced. The average male weight of O. niloticus juveniles, 26.89±2.98 - 27.35±2.74 g, were stocked at a density of 3 fish/m2 and were hand fed at 5-3% body weight two times daily, six days per week during 120 days in the triplicate earthen ponds. At the end of the feeding trial, daily weight gain values varied between 1.12±0.08 g/day and 1.21±0.06 g/day and survival rate ranged between 99.44±0.00 and 100%. No significant difference (p
