Abstract

To evaluate the efficiency of different probionts (Lactobacillus and Yeast) on Etroplus suratensis, three different pelleted diets were formulated with 30% protein and in which two diets were supplemented with probionts such as 2%Lactobacillus  (diet A) and 2% yeast (diet B) and a diet (C) without probiont was used as control. The water stability of these diets was studied as a function of exposure duration. The leaching percentage during 6 hrs period did not vary much between experimental diets (17.60 to 18.70%). The specific growth rate of E. suratensis revealed that the control diet fed fish have the lowest value of 2.93% against the highest values of 3.62 to 3.82% in probionts supplemented diets fed fishes. The gross production efficiency was also higher in probiontssupplemented diet fed groups than control group.
