The potential of Desert Locust By-product (DLBP) as a replacement for fishmeal in the diets of Oreochromis niloticus, its effects on the growth performance, nutrient utilization and immune response. Four iso-nitrogenous (35.64%) and iso-caloric (17.63 kJ/g) diets were formulated, in which DLBP was used as replacement for fishmeal at four replacement levels (0, 15, 30 and 45%). A total of 120 fingerlings of O. niloticus (8.14±0.03 g) were fed in a 90 day feeding trial. Each diet was fed to triplicate groups of 10 fish per tank at 3% body weight per day. Growth, feed conversion ratio (FCR) and other nutrient utilization parameters were monitored weekly. The blood samples were collected and analysed.Specific growth rate (SGR) and FCR ranges from (0.97±0.101.44±0.14 %) and (1.60±0.102.57±0.30) respectively, among different treatment at p<0.05. Packed cell volume (31.6 ± 5.6435.4±5.13 %), haemoglobin concentration (7.2±1.138.2±0.80 g/dl), red blood cells (2.52±0.432.82±0.38) and white blood cell (9.50±1.4511.94±2.95 ×1012/L) were significantly (p<0.05) different among the groups. There was no significant difference (p>0.05) in plasma biochemical indices (total protein (3.36±0.943.6±0.91 g/dl), albumin (2.20±0.342.68±0.54 g/dl) and globulin (0.90±0.141.18±0.29 g/dl)) among the groups. This study concluded that feeding O. niloticus fingerlings with DLBP up to 45%, could replace fishmeal without any form of physiological stress.
