Gut microbial community of wild fishes in Yangtze River

In aquatic animals, gut microbial communities shift with host development and living environment. Understanding the mechanism how environment impacts the gut microbial communities of aquatic animals is crucial for assessing and managing aquatic ecosystem health. Here, we proposed a simplified framework for the colonization and dynamic of gut microbial communities. Then, to quantify the colonization of environmental microbes in wild fish gut, the current study used 16S rRNA gene amplicon sequencing to get the structure of the water environmental microbial community and the gut microbial community in several wild fish populations from Yangtze River, and the relationship of these microbial communities were analyzed.
