This study was conducted to evaluate the effect of different levels of dwarf elder extract on growth performance, survival rate and immune parameters of common carp. For this purpose, fish with an average weight of 15.1±0.3 g were distributed in 12 fiberglass veniero with 30 fish density and fed for 56 days with different levels of dwarf elder extract including 0 (control), 2.5, 5, and 10 g per kg of feed. Based on the growth results, final weight (32.7±0.7 g), weight gain (17.5±0.5 g), increased body weight (115.4±1.9 %), specific growth rate (0.98 ±0.04 %/day), feed conversion ratio (2.31 ±0.05), condition factor (1.47±0.04), and protein efficiency ratio (1.03±0.08) in 10 g of dwarf elder extract/kg diet were significantly different from other treatments (p<0.05). Results of this study showed that there was a significant difference in survival rate among 10 g/kg extract/kg of feed treatment with other experimental treatments, especially control treatment (p<0.05). Results showed that there was a significant difference in the amount of lysozyme activity (46.2±1.7 IU/ml), alternative complement pathway hemolytic activity (66.0±5.8 mg/dl) and serum IgM (38.1±0.5 mg/dl) among 10 g/kg extract/kg of feed treatment with other experimental treatments, especially control treatment (p<0.05). In general, effect of dwarf elder extract, especially at 10 g/kg of diet, on the growth parameters, survival rate and immune parameters of common carp fry was evaluated positively.
