What disease is it when grass carp have red spots on their bodies?

Red spots on a fish's body indicate that the fish has hemorrhagic disease. The symptoms are that the sick fish's body surface turns black and loses its luster, and there is congestion in its mouth, muscles, bases of various fins, and other areas. In severe cases, because large amounts of congestion occur in other organs and tissues, the gills lose blood and become pale, showing white gills. In addition, sick fish also show poor appetite, sluggish movement, often swimming alone away from the group or swimming slowly in circles, physical wasting, and muscle atrophy. The disease mostly occurs from June to September, and the mortality rate is quite high.
