2. wet grass fresh soaking rice straw or other weeds thoroughly, put live fish in the middle, sprinkle water every 4 hours, and cover the fish limit, the fish can live for 12 hours.
3. Drop a few drops of high spirits on the fish's gills or gills to make the fish drunk, then put them into a ventilated wooden box and place them in a dark, cool, waterless place for 3 days.
4. Stick the fisheye fresh-keeping paper on the fisheye, which can make the fish live for about 5 hours.
5. Inflatable preservation of fish (also known as carbon dioxide preservation) the fish is packed in a sealed plastic bag filled with 60% carbon dioxide, 21% oxygen and 19% nitrogen, which can be kept fresh for a month at a low temperature of 1.1.

Treatment of a case of adult carp Aimeriasis
In early April 2005, a farmer came to us for medical treatment. The adult carp he raised recently did not eat and died. The number of deaths was small. In the early stage of the disease, one died in three or four days, and two or three died in recent days. The disease has been going on for more than a month. Once treated as enteritis, disinfectant was used for 3-4 days, and thiamphenicol was taken internally for 5 days, the death of fish did not decrease, and the condition did not alleviate. The dead fish can be seen that the fish body is black, the abdomen is enlarged, the abdomen is squeezed with the hand, and there is a white purulent outflow. In order to make a correct diagnosis, he was told to go back and get the sample of the diseased fish.
