Symptoms and Prevention and Control Methods of Hemorrhagic Disease in Grass Carp Aquaculture
Hemorrhagic disease is a fish disease caused by a reovirus. The virus particles are mostly spherical or hexagonal. The diameter of a complete virus particle is 68-72 nanometers, much smaller than the smallest bacterium. (1) Symptoms The main symptom of diseased fish is congestion. External symptoms generally show a slight reddish tinge, and in small fry, subcutaneous congestion can be seen under sunlight or lamplight. Some diseased fish also show congestion in the mouth, lower jaw, operculum, and base of the fins. When the skin of a diseased fish is peeled back, the muscles may show punctate or patchy congestion; in some cases the entire body musculature is congested, the gills are anemic and show "white gills," and patchy congestion of the gill lamellae may also occur, though some diseased fish show no such gill symptoms. The most common symptom in the internal organs is intestinal congestion; the whole intestine or part of it appears bright red due to congestion, and the mesentery and surrounding fat are also often accompanied by obvious punctate congestion, but the intestinal smooth muscle generally remains intact, with no rot or edema. A small number of diseased fish show grayish-white or locally congested liver, spleen, and kidney, and the swim bladder wall and gallbladder are often filled with blood streaks.
