Vibrio control for sustainable shrimp farming


Dr. Arun Jeganathan1, Dr. Godfred Ponraj Jeyaraj2 and Dr. P.E. Cheran3


Aaquaculture industry shoulders the responsibility of delivering good quality and protein rich seafood, free from antibiotics and chemical residues to the world. The shrimp aquaculture industry, that has witnessed tremendous growth in recent decades, has also been going through periods of turbulence : problems with increased disease prevalence due to the lack of acquired immunity in shrimps, which makes them likely to contract the same pathogen again and again. Controlling Vibrio in shrimp aquaculture is a big challenge at all levels, starting from broodstock maintenance to grow out ponds. Vibrio spp. are a ubiquitous set of bacteria that is among the causative factors for shrimp diseases such as Vibriosis, AHPND, RMS and White faecal syndrome. Vibrio severity can be identified with the signs and symptoms such as lethargy, reduced feed intake, reddishness, melanisation, necrosis, luminescence etc. Use of antibiotics, which had been practised traditionally to control pathogens is not safe and will also lead to multifaceted problems such as antimicrobial resistance. Shrimp farmers presently combat bacterial pathogens with probiotics as they are the safe and sustainable solution.
