ABSTRACT

Vibrio species are the most widespread pathogen in the aquaculture and all over the aquatic ecosystem. It causes a high rate of mortality in fishes and shrimps. There are few pathogens like Vibrio parahaemolyticus, vibrio anguillarum and vibrio vulnificus which have been display broadly for causing harm to aquatic vertebrates and invertebrates life. Vibrios are the mostly opportunistic pathogen, none the less it is to a great extent primary and secondary pathogenic that affect most of the shrimps present all over the globe and also causes huge economic loss for aquaculture sector. This study deals with recognizing the pathogenicity of Vibrio parahaemolyticus species on Macrobrachium rosenbergii and building up a successful treatment against the disease using the natural products. The present study conducted revealed that seaweed extraction of bioactive compounds carried out using different solvents can be utilized for treating the vibrio infection. This can be utilized as an intramuscular medication or by adding into the shrimp’s food for treating the disease in aquaculture and we aim to develop nutraceutical to overcome harmful effects of antibiotics.

Key words: Vibrio parahaemolyticus, nutraceutical, shrimps.
