Abstract A 63-day feeding trial was conducted to explore dietary yeast cell wall (YCW) on growth, immunity and disease resistance against Aeromonas hydrophila in gibel carp (Carassius auratus gibelio var. CAS Ⅲ) (initial body weight: 8.49 ± 0.27 g). Four isonitrogenous and isoenergetic diets were formulated to contain 0 % or 0.4 % three types of yeast cell wall (YCW) (termed as YCW0, YCW1, YCW2 or YCW3, respectively). Fish were randomly divided into 4 feeding groups in triplicates of 22 fish in each tank. Results showed that the highest final body weight was observed in fish fed YCW3 diet than the control (P 0.05). Dietary supplementation of YCW decreased condition factor, hepatosomatic index and viscerosomatic index (P 0.05). Hepatic IL-1β and TGF-β expressions were significantly down-regulated in the fish fed YCWs (P
