A study was conducted to assess the effects of grasshopper meal in the diet of Clarias gariepinus fingerlings. The aim was to substitute fishmeal with grasshopper meal in the formulation of Clarias gariepinus fingerlings feed. Feeds were formulated using different quantities of fishmeal and grasshopper meal and were used in feeding Clarias gariepinus fingerlings. Result shows that the best growth and feed utilization indices were recorded in the fingerlings fed 20% fishmeal and 10% grasshopper meal followed by those fed 15% fishmeal and 15% grasshopper meal. The least growth rate was recorded in fingerlings fed only 30% grasshopper meal. It could be concluded that Clarias fed with diet containing 10% grasshopper meal combined with 20% fishmeal produced the best growth rate.
