Abstract
India is one of the world’s leading shrimp producers. The shrimp hatchery industry also developed in parallel to this. Seed production is not constant due to various disease threats. Shrimp hatchery seed (Penaeus vannamei) production is depressed by various diseases, particularly caused by luminous bacteria (Vibrio harveyi), filamentous bacteria (Leucothrix mucor), and some viruses. Usage of various antibiotics becomes ineffective in many cases. It results in increased virulence of pathogens and poses a concern for the transfer of antibiotic resistance to human pathogens. Usage of probiotics provides a solution to these problems. The microbial species composition in hatchery tanks by adding selected bacterial species to displace deleterious normal bacteria. The virulence of luminous bacteria (Vibrio harveyi), can be controlled in this manner rather than an antibiotic Erythromycin. The abundance of luminous bacterial strains decreased in hatchery tanks where specially selected, probiotic strains of lactobacillus species were added. The luminous bacterial disease identified tanks were controlled by using probiotics (Lactobacillus species) than an antibiotic (Erythromycin) in a shrimp hatchery on the Chennai coast. The health of shrimp larvae and survival rate also increased to 80% after the application of the lactobacillus species as a probiotic.
