With the formation and development of the intensive breeding industry of Penaeus vannamei in South America, the frequent outbreak of Vibrio penaeus monocytosis is one of the most headache diseases for farmers, and vibriosis has a strong contagiousness, the infection rate can reach 100%, the mortality rate of pond shrimp with serious disease can reach more than 90%, many farmers do not know what to do after encountering Vibrio disease of Penaeus vanillium, can only watch a large number of deaths of shrimp, they have no way, the following will introduce to you the knowledge about shrimp vibriosis, What should I do about vibriosis?
First of all, Vibrio is not a specific species of germ, but Vibrio family and Vibrio genus, and the common Vibrio in the shrimp farming process are Vibrio parahaemolytic, Vibrio algae, Vibrio trauma, etc., Vibrio bacteria can cause Vibrio shrimp disease, and is still the most common and harmful bacterial disease in the shrimp farming process. When the water quality environment deteriorates, the shrimp resistance is reduced, and Vibrio will take advantage of the void.
Secondly, after the shrimp infection with Vibrio, the shrimp with mild symptoms began to have unclear feeding lines, the color of the liver and pancreas became lighter, the body was reddish, the gills of the shrimp were yellow, and the shrimp with severe symptoms had a broken intestine, jejunum, liver and pancreas whitish, dead shrimp, poor feeding of live shrimp, and serious seedling loss. In the later stage, the shrimp jejunal jejunum is empty, and some shrimp intestines are filled with yellow pus, the gills are yellow, the liver and pancreas are enlarged, white, etc., which induces death.
Finally want to prevent vibrio first to improve the physique of shrimp, regular internal administration of the hero liver and gallbladder, can improve the immunity of shrimp, if there has been a shrimp vibriosis can be added to the feed with fishing fox internal service, can be targeted to remove vibrio genus and other harmful pathogenic bacteria, reduce the type and number of pathogenic bacteria in the water body, reduce the incidence of bacterial diseases, but also has water quality improvement, enhance immunity, anti-bacterial infection effect.
