    Abstract

    The world human population is growing on an exponential phase and pace. Aquaculture, raising of aquatic animals in artificial or facilitated ecosystem, is evolving as the rapidly growing food production sector globally. The growth of aquaculture industry has been speculated to be inevitable that may certainly contribute toward meeting the food security of growing global population. India, with a vast coastline and enormous marine resources, is having greater potential to build up this industry as a productive economic sector. However, the bacterial infections in aquaculture hatcheries and farms cause a huge loss in productivity and remain a major challenge for the growth of this vital industry. Considering the ill effects to environment and public health, risk of development of antibiotic resistance, and persistence of antibiotic residues in aquaculture animal foods, it has necessitated the regulatory bodies across the globe to restrict the usage of antibiotics for aquaculture disease management. Hence, finding alternate measures for the aquaculture disease management in both hatcheries and forms is the current need. It has been well documented that exhibition of virulence factors and formation of biofilms are the major factors for the establishment of disease in aquaculture animals by the bacterial pathogens. Both these factors are being regulated by quorum sensing (QS), which is a population density-dependent expression of selected phenotypes in a coordinated manner through the production of autoinducers (AI). Quorum quenching (QQ) is a disruption of quorum sensing. Thus, QQ is considered as one of the most preferred preventive strategies for the ecofriendly management of aquaculture infections. The AI molecules involved in gram-positive and gram-negative QS system and also the enzymes and molecules involved in QQ are also widely studied in aquaculture systems. This chapter would provide an overview of QS and QQ systems being operated among aquaculture pathogens and other beneficial organisms in the aquaculture system with more emphasis on shrimp aquaculture. This chapter also emphasizes the recent developments on the impact of QS and QQ with special reference to the virulence of bacterial pathogens both in vivo and in vitro with a short focus on future perspectives of QQ and QS for the disease management in aquaculture systems.
