The concept of probiotics is widely applied in the field of aquaculture for their beneficial and friendly influences. In this sense, the role of Saccharomyces cerevisiae on the growth, immune and antioxidative responses of European seabass was tested in this study. Fish were distributed in 3 groups (triplicates) with ten fish in each replicate and fed 0, 1, and 2 g/kg of S. cerevisiae (15×109 CFU/g) for 90 days. Fish fed S. cerevisiae showed higher final body, weight gain, and specific growth rate as well as lower FCR than fish fed the basal diet (P<0.05). The RBCs, WBCs, Hb, and PCV values were increased in fish fed dietary S. cerevisiae when compared to the control (P<0.05). The blood total protein, albumin, and globulin were higher in fish fed S. cerevisiae than the control (P<0.05). Fish fed dietary S. cerevisiae had enhanced phagocytic index, phagocytic, and lysozyme activity comparing the control. In a similar sense, the antioxidative enzymes (SOD, GPx, and CAT) were higher in fish fed S. cerevisiae than the control (P<0.05). However, the level of MDA was lowered (P<0.05) by S. cerevisiae in European seabass. Gene expression of IL-8, IL-1β, GH, and IGF-1 was upregulated and HSP70 was downregulated by S. cerevisiae (P<0.05). It can be concluded that European seabass fed S. cerevisiae at 1–2 g/kg (15×109 CFU/g) diet had markedly enhanced growth, haemato-biochemical, and immune performances.
