Common carp fingerlings (n=240, w=4.56±0.17 g) were supplied, randomly stocked in 12 aquaria and fed with experimental diets for 7 weeks. The results revealed no significant differences between performance parameters of fermented A. oryzae fed test and control diets (p˃0.05). Also, evaluation of haematological parameters (RBC, Hct, Hb) and white blood cell (WBC) counts showed no notable changes between experimental groups (p˃0.05). However, respiratory burst activity was meaningfully higher in fish fed fermented A. oryzae compared to control group (p<0.05). The present results showed that possible effects of administration of fermented A. oryzae on immune responses in carp fingerlings. M3 ER -
