Response of finescale dace (Phoxinus neogaeus) gut microbiome to in situ experimental selenium exposure

Selenium is an environmental contaminant of global concern that can cause adverse effects in fish at elevated levels. Fish gut microbiome play essential roles in gastrointestinal function and host health and can be perturbed by environmental contaminants, including metals and metalloids. Here, an in-situ selenium (Se) exposure of female finescale dace (Phoxinus neogaeus) using mesocosms at the International Institute for Sustainable Development - Experimental Lakes Area (IISD-ELA) was conducted to determine the impacts of Se accumulation on the gut microbiome and morphometric endpoints. 16S rDNA metabarcoding was employed to describe the gut microbiome. This dataset includes the demultiplexed sequencing output, the feature table with rarefied counts, the taxonomic annotations of sequences, and the sample metadata.
