The effect of Bio‐Mos incorporated into feed formulation on the growth, feed utilization, body composition and histological response of sea bass ( Dicentrarchus labrax ) was investigated. Final fish weight, feed conversion ratio ( FCR ), specific growth rate ( SGR ), protein efficiency ratio ( PER ), protein productive value ( PPV ) and energy utilization ( EU ) of sea bass feed Bio‐Mos supplemented diet and the control diet were determined at the end of experiment. Data present mean ± SD from triplicate determination ( n = 3) for a 75‐day feeding trial. Different concentrations (0.5, 1.0, 2.0. 3.0 and 4.0 g kg diet −1 ) of Bio‐Mos supplementation and a control without Bio‐Mos incorporation were fed to the fish, feed in the form of dry diets. Average final weight was significantly higher at 1.0 g kg diet −1 of Bio‐Mos and lowest in control fish group; SGR significantly higher at the 1.0 g kg diet −1 of Bio‐Mos. In addition,, PER , PPV and EU showed the same trend. The chemical body composition, crude protein, dry matter, crude fat and ash were significant ( P ≤ 0.01) compared to control groups. We concluded that 1.0 g kg diet −1 of Bio‐Mos improved the growth, feed efficiency, histology intestine and survival of sea bass.
