16S rRNA metagenome analysis of gut bacteriome of Rohu ( Labeo rohita ) from Halda River and Kaptai Lake, Bangladesh

Key Points

• Distinct gut microbiota profiles were identified, with significant differences between Halda River and Kaptai Lake samples.
• The Halda River Rohu fish gut samples showed a higher concentration of pathogens compared to Kaptai Lake samples.
• The Kaptai Lake samples exhibited a greater abundance of beneficial probiotics, suggesting environmental impacts on gut health.
• Using 16S rRNA sequencing enabled a detailed analysis of these microbial communities in both aquatic environments.
