Abstract

Vibriosis is a common disease in vertebrates and marine invertebrates that occurs in warm water marine fish(tropical area with temperature above 15 centigrade degree and high salinity) by different species of Vibrio genus bacteria (Vibrio sp.) as Harvey's clade. It is considered as one of the main challenges for the production of marine fish and Asian seabass, causing significant losses, especially in aquaculture systems in cages. Many researchers point out that marine vibrio is a major cause of bacterial disease in marine aquaculture, and pointed out that in order to prevent the onset of vibriosis, a serious effort should be made to determine the virulence (pathogenic potential) of various species of vibrio, their pathogenicity and the production of vaccine strains should be done. In the study of status of the vibriosis disease of cultured Asian seabass in the southern provinces of Iran vibrio harveyi have been isolated as the dominant isolate by biochemical and molecular identification of the cultured Asian seabass in different weights and in different seasons of the year. The results of this study indicate a high prevalence of Vibrio harveyi in marine bass fish farms, which is essential for the prevention of vibriosis.
Key words: Asian seabass, Vibriosis disease and Vibrio harveyi.
