The effects of dietary β-glucan administration on non-specific immune parameters in Oliver flounder, Paralichthys olivaceus were evaluated. In this study investigated the effects of mushroom mycelium mixed solution extract (MMSE) on the immune responses of olive flounder, Paralichthys olivaceus. The culture extracts were evaluated for the growth, hematology, lysozyme activity, leukocyte phagocytic activity, and disease resistance against Vibrio anguillarum. In the effect of the growth, the body weight and length gain in the group, which fed with mushroom mycelium cultural extract, were the body weight 52 g and length gain 2.1cm higher than that in the control. For the hematology, the administration of MMSE resulted in increase of glucose. However, there was no distinct differences in GOT (glutamic oxaloacetic
transaminase), GPT (glutamlc pyruvic transaml- nase), TG, TP, and LDH (lactate dehydronase) among each group. The activities of Lysozyme were 80% higher in the experimental groups than in the control. The activities of Leucocyte were 66% higher in the experimental groups than in the control. Although lysozyme activity and leucocyte activity showed somewhat decrease after 12 weeks, these activities were still higher than in the control. The relative percent survival rate (RPS) after an artificial challenge with 7˟108 CFU of Vibrio anguillarum per fish was 25% higher in
the experimental groups than the control.
