Abstract: The study aimed to searching for an efficacious medicine curing sturgeon disease. Water extracts from Chinese herbs were screened against Aeromonas veronii by tube dilution method,the minimum inhibitory concentrations(MIC) were determined.Best combination was determined by orthogonal experiment. 33 kinds of Chinese herb water extracts had different bacteriostatic activity against Aeromonas veronii. Among these herbs,Rhus chinensis Mill. had the lowest MIC against Aeromonas veronii (0.97 μg/mL),which was better than Sanguisorba officinalis L. and Scutellaria baicalensis Georgi,both with MIC of 1.95 μg/mL. However,Portulaca oleracea L. and Sophora flavescens Ait had the highest MIC against Aeromonas veronii (250 μg/mL). The best combination against Aeromonas veronii contained Rhus chinensis Mill.,Sanguisorba officinalis L.,Euphorbia humifusa Willd. and Forsythia suspensa (Thunb) Vahl,the ratio was 1∶2∶4∶8. The combination had a good bacteriostatic effect. The results would provide evidences for further caring diseases of aquiculture by Chinese herbs.
