A Fish feeding trial was conducted in a closed recirculation water system for 8 weeks to study the effect of broken lentil seeds as a dietary plant protein instead of soybean meal protein (0, 25, 50, 75 and 100%) on growth performance, feed utilization digestibility and economical study of tilapia fries. Four hundred and fifty tilapia fries (Oreoehramis niloticus) with an average initial weight of 0.3g/fish were randomly distributed into fifteen aquaria (30 fry/aquarium) water volume in each aquarium was 70 litter. The fish were fed daily at a rate of 1.7% of their metabolic body weight (W)⁰.⁸ with isonitrogenous (30% CP) and isocaloric (4600Kcal GE/kg) diets. Each diet was given to three replicate aquaria. Chemical analysis of broken lentil seeds showed high contain of CP (26.69%), CF (12.45%), NFE (55.33%), however, its contain of EE (2.45%) and Ash (2.99%). Results indicated that broken lentil seeds contains reasonable amount of CP (amino acids profile, but lower than that present in soybean meal) and its high contain of NFE which is an indicator for its potential value as a source of a plant protein and energy.
