Effect of different dietary protein sources on fingerling production in Nile Tilapia (Oreochromis niloticus)

International Journal of Fisheries and Aquatic Studies, 2019; 7(2): 1-5Availability of quality and reliable feeds is one of the main challenges facing aquaculture development. A 12 week experiment was set where, broodstock of Nile tilapia were fed various diets with different plant protein sources for 8 weeks. The produced fingerlings were fed a common diet thereafter for 4 weeks. The diets contained Fish meal, maize meal and minerals; Moringa leaf meal, maize meal and minerals; Sunflower seedcake, maize meal and minerals; Moringa leaf meal, sunflower seedcake, maize meal and minerals. All other factors including water quality parameters were constant in all experimental units. It was noticed that, fish brood stock fed diets 1 and 2 produced highest numbers of fish fingerlings, but fish fingerlings produced by brood stock fed diet 2 showed the greatest growth and survival. This study therefore recommends diet 2 (Moringa leaf meal, maize meal and minerals) for broodstock feeding. The ingredients are readily available for use in aquaculture production
