Study of metagenomics of Barilius bendelisis (Hamilton, 1822) fish species

Abstract

Barilius bendelisis is a freshwater fish species belonging to the family of Cyprinidae. It is a common fish found in the Hel river of Kokrajhar, Assam, India and has a good population density. In the present study, the metagenomics study of B. bendelisis fish species collected from the Hel river was conducted. In the study, genomic DNA (gDNA) isolation was carried out followed by DNA confirmation and quantification. It was found that the high abundant level of the taxonomic distribution of the phylum was Firmicutes (74.8%), the class was Clostridia (74.8%), the order was Clostridiales (74.8%), the family was Veillonellaceae (74.6%), the genus was Citrobacter (7.7%) and the species was morganii (2.4%). Various types of bacterial microbiome were also detected in the gut sample and this variation may be due to fish habit, fish feed, and environmental conditions.
