Vibrio disease is a disease caused by Vibrio, which is the most common bacterial disease of marine fish. Comparison of vibriosis The same disease is skin ulcer on the body surface. At the initial stage of infection, the body color mostly faded in patches; Loss of appetite, swimming slowly on the water; Moderate infection, refers to the root and trunk redness or punctate bleeding; With the development of the disease, the affected tissue infiltrates into hemorrhagic ulcer, some scales fall off, segments and fin membranes rot, intraocular bleeding, anal swelling and expansion, and yellow mucus often flows out. The infection of PARALICHTHYS olivaceus, Sparus macrocephalus and Sparus macrocephalus in the seedling stage can make the stomach sac of the sick fish swell especially, resulting in "abdominal distension", and even make the abdominal wall rupture and the stomach sac protrude out of the body. When PARALICHTHYS olivaceus was infected in the larval stage, the infected population gathered in the side wall or corner of the fish pond and did not eat, so its vitality decreased and "intestinal turbidity" appeared. The diseased fish's body surface faded, the fin base and fin membrane subsequently bled, and the scales fell off, which led to ulcers, red and swollen anus, exophthalmos, intraocular bleeding, white eyeball, intestinal turbidity, abdominal swelling, bleeding and inflammation in the dissected fish.

Vibrio disease is a common disease, which occurs in marine fish. The cause of the disease is sediment pollution, high density and poor bait.

For the prevention and treatment of vibriosis, it is necessary to control the breeding density and maintain excellent water quality and sediment. When sick fish are found, they should be taken with chloramphenicol or photoperiod or fish kangning plus fish multidimensional for three to five days, then sprayed with bromochlorohydantoin or dibromohydantoin for three hours, and then sprayed with aquatic product Shen No.2 twice.
