Abstract: A total of 180 individuals of Nile tilapia Oreochromis niloticus with an initial body weight of(52.98±0.33)g were randomly divided into 6 groups with 3 replicates per group，10 fish per replicates， reared in an indoor tank(100 cm×50 cm×50 cm)and fed basal diet(control group A)， and the basal diets supplemented with vermicompost at a rate of 2.5%(group B1)，5.0%(group B2)and 7.5%(group B3)， and with mixture of vermicompost and earthworm powder at a ratio of 5.0%＋0.150%(group C1)and 7.5%＋0.225%(group C2)for 60 d.The growth performance and serum antioxidant indices were analyzed and compared with Tukey multiple comparison analysis method to investigate the effects of dietary vermicompost and earthworm powder on growth performance and serum antioxidant indices in Nile tilapia.The results showed that there was 57.93%of crude protein in the earthworm powder and 3.81%of crude protein in the vermicompost.Nile tilapia in groups B1， B2， B3， C1， and C2 had slight lower food conversion ratio， and higher specific growth rate， weight gain and serum antioxidant indices， the best in the fish in group B2.Tukey multiple comparison analysis revealed that there was no significant difference in all indices(P＞0.05).The findings provided the theoretical reference and data for reasonable application and development of vermicompost and earthworm powder as feed additives in aquaculture.
