The most serious damage to the first-age grass carp. Since the 1970s, domestic scholars have done a great deal of research work in the pathogenesis and prevention of the disease, but few studies have been conducted on the histopathology. Since 1984, the Shanghai Fisheries University and the Chinese Academy of Sciences Institute of Hydrobiology, has made a lot of research in this regard, we also carried out since 1985, grass carp hemorrhagic histopathology. Materials and methods for observation of sliced ​​grass carp a total of 35, the specification for the full length
