Abstract: The study was carried out to determine the influence of dietary supplementation of commercial probiotic, Bactofort ® on growth, haematological parameters and survival of Clariasgariepinus fingerlings raised in plastic tanks . The experiment was conducted for two months (61days) at the Fisheries laboratory, Department of Fisheries and Aquaculture, Federal University Dutsin-Ma. One hundred and twenty fingerlings of C. gariepinus with average weight of 11.3 g, were weighed and randomly distributed into four treatment groups consisting of twelve plastic tanks as follows: T0, which is the control group with no probiotic inclusion; T1, T2 and T3, representing 1, 2 and 3g of probiotic (Bactofort ® ) supplementation respectively. All treatments were in triplicates. Fish were fed to satiation two times daily, seven days a week (morning 8.00am and evening 5.00pm ). The growth performance (Final Mean Weight, Mean Weight Gain, Percentage Mean Weight Gain, and Specific Growth Rate) and nutrients utilization (Mean Protein Intake, Feed Conversion Ratio and Protein Efficiency Ratio) of C. gariepinus fingerlings in all probiotic treated groups of Bactofort ® increased relative to the control group. The best growth performance was obtained using Bactofort ® at 3g/kg dietary supplementation. Haematological parameters (Haematocrit, Haemoglobin, Mean Corpuscular Volume, Mean Corpuscular Haemoglobin, Mean Corpuscular Haemoglobin Count, Red Blood Cell Count, White Blood Cell Count, Heterophils, Lymphocytes, and Eosinophils) were enhanced in comparison with the control. Percentage survival during the research period, ranged from 76.67 - 86.67% in all probiotic treated groups in comparison to 53.33% recorded in the control. In conclusion, administration of Bactofort ® , increased growth performance, nutrient utilization, haematological parameters and survival of C. gariepinus fingerlings. Bactofort ® is recommended for inclusion in C. gariepinus fingerlings diet at 3g/kg.
