为研究用红鱼粉替代白鱼粉，并在替代饲料中添加两个不同梯度海洋红酵母对大菱鲆生长性能、体成分以及形体指标的影响。试验用白鱼粉、红鱼粉、海洋红酵母1 g／kg＋红鱼粉、海洋红酵母2 g／kg＋红鱼粉4种等氮等能的试验饲料分别饲喂初始体质量（213．48±0．23） g的大菱鲆，480尾试验鱼随机分为4组，每组设3个重复，每个重复40尾，试验期为6周。试验结果表明，与红鱼粉组相比，海洋红酵母1 g／kg＋红鱼粉组可显著提高大菱鲆的摄食率、相对质量增加率、特定生长率及蛋白质效率（P＜0．05），效果与白鱼粉组相当，高于海洋红酵母2 g／kg＋红鱼粉组，但差异不显著（P＞0．05）。各试验组大菱鲆的体成分和形体指标差异不显著（ P＞0．05）。据此，添加海洋红酵母1 g／kg即能显著提高大菱鲆对红鱼粉替代白鱼粉饲料的摄食率、蛋白效率和生长性能，使得红鱼粉替代组的饲料性能达到了白鱼粉组的生长水平。

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 .
