Abstract: The effects of mill moth (Ephestia kuehniella) egg meal (IEM) upon growth performance and fatty acid profile of common carp (Cyprinus carpio) (1.12 ± 0.01 g) were evaluated in triplicate groups for 12 weeks. Three isonitrogenous (35% CP) and isocaloric (17 MJ kg?1) diets were formulated replacing fishmeal with 0% (G-0), 50% (G-50), and 100% (G-100) IEM. The results of the trial indicated that G-50 had the highest growth performance values and a more efficient FCR (1.79). Replacement levels of IEM did not have any significant effect on survival. Total monounsaturated fatty acids (MUFA) were found to be statistically different for all diets, and Σ SFA in fish was decreased with the increasing IEM levels. The ratio of n3/n6 was higher in G-0 reflecting a better balance. The results suggested that 50% replacement of IEM with fishmeal enhanced growth performance in common carp without any adverse effect on fatty acid profile, but investigation of the long-term effects has still been needed.
