Description

technical field [0001] The invention belongs to the field of traditional Chinese veterinary medicine preparations, in particular to a traditional Chinese medicine oral liquid for treating grass carp bacterial gill rot and a preparation method thereof. Background technique [0002] The source of bacterial gill rot of grass carp is Myxococcus ichthyosa, which mainly harms grass carp and herring. It begins to occur at 15°C, and the higher the water temperature at 15-30°C, the easier it is for epidemic outbreaks and the shorter the lethal time. [0003] The symptoms are that the fish body turns black, and the middle part of the gill cover is often eroded into a ball or an irregular transparent window. Increased mucus on the gills and swollen gill filaments. Some parts of the gills are reddish or off-white due to ischemia. Some parts turned purple due to local blood stasis, and even had small bleeding spots. In severe cases, gill flakes fall off, and the ends of gill filament...
