摘要： Nowadays, effective microorganisms (EM) is wildly employed in water improvement and agricultural utilization. Many experiments in aquaculture have proved that EM takes positive effects on fish. Naturally, the present experiment evaluated the influence of supplemental EM in feed on tilapia, which contains the growth, immunity, and appetite regulating of juvenile GIFT tilapia. Three different EM-concentration diets (0 g/kg; 30 g/kg; 60 g/ kg) were fed to tilapia for 90 days. The results showed that Low and High concentration could promote fish grow. However, most of the serum indicators suggested the little improvement of the immunity in tilapia. The neuropeptide Y (npy) and agouti-related protein (agrp) in brain or cholecystokin (cck) and Ghrelin in hepatopancreas mRNA expression were significantly improved by EM diets. According to the study, fish growth indicated the results of gene expression, thus adding EM to diets suggested positive effects on tilapia culture. The study provided information to aquaculture production.
