ISOLATION, IDENTIFICATION AND BIOCHEMICAL CHARACTERIZATION OF VIBRIOS SPECIES FROM SHRIMP HATCHERIES NEAR PONDICHERRY COAST, TAMILNADU, INDIA

One of the major fastest growing food sectors globally seems to be the aquaculture industry which ensures a high protein resource to the world due to the exploitation of natural protein resources. One of the major problem in shrimp culture is the disease caused by the bacterial invasions particularly that of vibrios. Some of the important vibrio species that causes the devastation are Vibrio harveyi, Vibrio splendidus, Vibrio parahaemolyticus, Vibrio alginolyticus, Vibrio vulnificus, Vibrio damsella, Vibrio anguillarum, Vibrio orientalis etc. In the present study the vibrios associated with shrimp hatcheries near Pondicherry coast were isolated, identified and biochemical studies were performed along with the vibrio load from the water samples taken from the larval rearing section, post larval rearing section and nauplli. The isolated and identified vibrios were found out to be Vibrio vulnificus, Vibrio alginolyticus and Vibrio parahaemolyticus based on the biochemical characterization and by selective media plating.
