Abstract
Aquaculture has grown rapidly during the last few decades due to research and developmental activities but we are still unaware of the various microbial species thriving within the aquaculture systems and their specific roles for knowing that Mmetagenomics study required environmental sample to discover the unexplored microbial community. The aim of this present study is to characterize the gut microbiota of giant tiger shrimp, Penaeus monodon collected gut sample and16S rRNA gene-based high-throughput sequencing revealed distinct and diverse microbial communities. The results showed a high abundance of Betaproteobacteria, followed by Alphaproteobacteria, Clostridia, Actinobacteria, Gammaproteobacteria and Bacilli found in the gut sample Microbes that play essential roles in nutrient cycling and mineralization of organic compounds such as Bacteroidetes, Planctomycetes, Gammaproteobacteria, Firmicutes, Cyanobacteria, and Actinobacteria could also be identified. Due to the strong influence of the gut microbiota on fish health, dominant bacterial species in the gut are strong candidates for probiotics. These findings provide valuable information on the microbial community and contribute to controlling the diseases in shrimp farms.
