Abstract：This experiment was conducted to investigate the effects of replacement of white fish meal by brown fish meal and two different gradients of marine yeast Rhodotorula benthica on growth performance , body composition and body indication of turbot Scophthalmus maximus .Four isonitrogenous and isoener-getic diets were formulated and contained 58% white fish meal as a control diet (W) .The diet contained 58% brown fish meal named B .The experimental diets ( B+1 ,B+2 ) were respectively supplemented with 1 g/kg ,and 2 g/kg the yeast on the basis of brown fish meal .Four hundred and eighty turbot with body weight (213 .48 ± 0 .23) g was randomly divided into 4 groups with 3 replicates per group ,and 40 fish per replicate for six weeks .The results showed that compared with B ,addition of 1 g/kg the yeast in the basis of brown fish meal significantly improved the the feeding rate ,relative weight gain ,the specific grow th rate and protein efficiency rate of turbot (P<0 .05) ,a similar level as W and a higher level than in B+2 group (P>0 .05) .There were no significant difference in body composition and body indication of turbot (P>0 .05) .In conclusion ,addition of 1 g/kg into brown fish meal can significantly improved feed-ing rate ,protein efficiency rate and growth performance of turbot ,a similar growth level as white fish meal .
