Abstract
The density and diversity in the vibrio species on the body parts of some commercially
important fishes of India were studied with respect to the habitat viz pelagic and demersal.
The distribution of vibrios on fish from these habitats showed wide variations both
quantitatively and qualitatively. The results indicate that the density of vibrios on the skin
and gills may be more in pelagic fish compared to demersal types. However the intestinal
count of vibrios is similar in the two categories. The species diversity was more in the demersal
fishes particularly in the intestinal samples.The vibrio species were in the order of dominance
as V. alginolyticus, V. orientalis, and V. campbelli. Species like V. alginolyticus, V. parahaemolyticus,
V. vulnificus and V. mimicus were among the pathogenic species isolated from the fish samples.
The study reveals that vibrios constitute a major portion of the total bacterial flora in tropical
fish.
