Abstract: Pearl spot (discolourised skin, hemorrhagic patches, bloody blotches around fins and mouth of fish) Etroplus suratensis, Cichlidae family were identified at backwaters of Muttukadu, CIBA and Chennai.  Diseased fishes were collected and the causative agent isolated from tissues of kidney. A control set of fishes were inoculated with Vibrio vulnificus and it produces the identical signs of vibriosis. Based on morphological and biochemical characters, the pathogen identified as V. vulnificus. Further, the virulence of V. vulnificus tested by Lethal Dosage (LD50) experiment and sensitivity/resistant patterns also assessed by Bauer–Kirby method.
