.— A 8‐wk trial was performed with white sea bream, Diplodus sargus , juveniles (17.3 g initial weight) to evaluate the effect of dietary lipid levels on growth performance and whole‐body composition. Six experimental diets were formulated to be isoproteic (45% protein) and to contain from 9 to 24% dietary lipid levels (dry matter basis). Fish meal and fish oil were used as the main protein and lipid sources, respectively. At the end of the trial, there were no significant differences ( P > 0.05) among groups in fish performance or in whole‐body composition. From the results of this trial, it is concluded that, within the range of values tested, increasing dietary lipid levels above 9% has no advantage as it does not promote growth or spare protein for growth purposes.
