　　Gallnut extract was added to the feed of penaeus vannamei, and the inhibitory effects of two methods of extract addition and different feeding time on Vibrio parahaemolyticus were studied. The results showed that the minimum pathogenic concentration of Vibrio parahaemolyticus was 1×105cfu/ml. The optimum bacteriostatic concentrations of the two different extraction methods were 1% water extract feed and 0.5% alcohol extract respectively; gallatia japonica extract was directly put into water, which had certain toxic and side effects on vibrio, but it was not as effective as mixed feed; In terms of feeding time, continuous feeding of gall extract for 5 d has the best antibacterial effect, and continuous feeding of gall extract for more than 10 d will cause toxic and side effects. conclusion: the water extract of gall can effectively inhibit the side effects during the culture of Penaeus vannamei. vibrio haemolyticus.
