XU Ming et al(Jiangxi Vocational College of Biological Technology,Nanchang,Jiangxi 330200)  
[Objective] The study was to control the hemorrhagic disease of grass carp and increase the survival rate of grass carp.[Method] Tongwei feedstuff with which the immunopotentiator such as astragalus polysaccharide,vitamin K3 powder,isatis root and Vc were mixed was taken to feed grass carp in 4 water areas,the preliminary therapeutic test on hemorrhagic disease of grass carp was conducted.[Result] In water area 1,there were no grass carps died because of disease on the 4th day after administration,and then there were no hemorrhagic disease of grass carp appeared.In water area 2,the grass carps were fed by drug on June 24 and were cured on June 26,and then the hemorrhagic disease of grass carp had no recurrence.In water area 3,the recovery of the grass carps appeared on the third day after administration and no recurrence was found.In water area 4,the death of grass carps stopped on the 4th day after administration and no recurrence was found.[Conclusion] When proper amount of astragalus polysaccharide,vitamin K3 powder,isatis root and Vc were added into grass carp feedstuff,the resistant ability of grass carp on viruses could be increased and the therapy effect on hemorrhagic disease of grass carp could be obtained and it had hepatic-protective and choleretic effect on grass carp when the proper amount of isatis root was added into the feedstuff.
