Abstract: The objective of this work was to study the effect of dietary protein and lipid levels on common meagre by assessing the effect of the protein/lipid ratio (P/L) on the growth performance and food conversion. Four diets (A1, A2, A3 and A4) with P/L respectively of 4.66, 3.88, 3.28 and 2.84 were tested on two replicates of fish with an initial weight of 44.7±0.9g during 11 months. Body weight presents two phases of growth in all treatments corresponding to low and high temperature periods. Fish fed on A1 exhibited the best SGR (0.4±0.021). However, no statistical differences were observed between the treatments. FCR and EER were better in A1 and showed significant difference (p<0.05) between the four lots. Survival rates varied from 94 to 96%. The results of this study suggest that the decrease of the P/L ratio in the diet affects negatively the growth and feed utilization in meagre.
