The Assembly of Fish Gut Microbiomes Through Habitat Variation Provides Insight Into Redbelly Tilapia Invading a Large Subtropical River.

ABSTRACT: The environment in which fish reside markedly shapes the composition of their gut microbiome. However, the precise mechanisms by which the assembly process of fish gut microbiota adapts to diverse habitat conditions remain largely uncharted, especially in the case of invasive tilapia, renowned for its remarkable adaptability to environmental changes. In this study, we employed high-throughput 16S rRNA gene sequencing to explore the gut microbiome of redbelly tilapia from three distinct habitats. Our results showed substantial disparities in both the composition and diversity (alpha and beta) of the gut microbiome between wild and pond-cultured redbelly tilapia. Notably, stochastic processes emerged as the dominant forces governing the assembly of the gut microbial community in redbelly til
