Abstract
India is one of the world’s leading shrimp-producing countries. The shrimp hatchery industry also developed in parallel to this. Seed production is not in a constant manner 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 increases in the virulence of pathogens and, furthermore, is a cause for concern in promoting 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 filamentous bacteria (Leucothrix mucor) is controlled during this experiment. In this study, it reveals that the probiotic not only controls the pathogenic bacteria (Leucothrix mucor), but also it improves the water quality and animal health.
