Shrimp aquaculture is the rapidly growing sector of fish culture producing sectors in the world due to its rising demand in developed countries. Moreover, the intensive and extensive shrimp culture systems are affected mainly by infection diseases caused by several pathogenic agents and resulting in high economic losses. Nowadays, controlling and preventive infection diseases are the major concern to develop this sector. Besides, the highly extensive usage of chemotherapeutics and antibiotics induced numerous drawbacks in shrimp farming, developed antibiotic resistance bacterial strains, and threatens the aquatic life. Recently, improving the immunity status and controlling infectious diseases using biological methods have become beneficial, environment friendly, and risk-free options in aquaculture. Probiotics have gained much attention as immunostimulants in aquaculture owing to their inhibitory properties on pathogenic microorganisms via creation of an unfriendly atmosphere to cease their growth. Lactobacillus species as probiotics was used in shrimp aquaculture to prevent viral infections due to their positive promoting effects on survival and health. Additionally, Lactobacillus species possesses sturdy antimicrobial activity against various pathogenic microorganisms such as Photobacterium and Vibrio infections. This review threw the light on the applications of Lactobacillus sp. as probiotics in cultured shrimp which could be of great impact from a sustainable, intensive, and ecofriendly aquaculture opinion.
