FIGURE 4

Co-occurrence analysis of the gut microbes (genus level) of the three cold-water fishes (with Spearman index; ρ = 0.5) (A–C). The top 60 genera were used to generate the co-occurrence networks. The node represents the bacteria genus, the size of the node represents the relative abundance, and the color indicates their taxonomic assignment. The red line between the nodes represents a positive correlation, and the blue line indicates a negative correlation.
