FIGURE 5.

Phylum level RDP v14 taxonomy applied to the 16S rRNA V4 gene amplicons detected in environment-associated and gut-associated microbiota samples taken from strains of blue I. furcatus (n = 21) and channel catfish I. punctatus (n = 21) at 193 days post hatch. Reads assigned to cyanobacteria/chloroplast, NA, or unknown at the phylum level, samples with less than 10,000 processed reads, and SVs accounting for less than 1e^-5 of the relative abundance were removed prior to plotting. Results are displayed as mean relative abundance for each fish strain, with horizontal black lines delineating the abundance of unique SVs assigned within a single phylum.
