All the probiotic supported ration fish groups gave special poultry star®me on level added 0.5 gm/1kgsignificanthigher (p<0.05) body weight gain, growth rate, relative growth rate, specific growth rate, feed conversion ratio, feed efficiency ratio, protein efficiency ratio and protein productive value than the control fish group.
