Abstract: This study aimed to investigated the effects of dietary supplementation with fermented soybean meal Tejiao 001（fermented soybean meal）on the growth performance of California perch. California perch fry with the body weight of about 14 g were taken as the research object and fed with circulating water. The experiment was divided into 6 groups. The diets were supplemented with 0%，5%，7.5%，10%，12.5%，and 15% fermented soybean meal， respectively，this study lasted for 6 weeks. The results showed that dietary supplementation with 5% fermentedsoybean meal significantly increased the weight gain rate（WGR）and specific growth rate（SGR）of California perch （P＜0.05），and feed conversion ratio （FCR） of 5% fermented soybean meal group and control group were significantly better than those of 12.5% and 15% fermented soybean meal groups（P＜0.05）. The feed conversion ratio in 7.5% fermented soybean meal group was significantly better than that in 15% fermented soybean meal group（P＜ 0.05），while there was no significant difference in fecal breakdown among all groups（P>0.05）. The results showed that the basal diet supplemented with 5% or 7.5% fermented soybean meal could improve the growth performance and feed efficiency of California perch，but with the increase of fermented soybean meal，the growth performance indexes and feed efficiency of California perch decreased.
