Figure 2: Panel A: Pie charts showing BC diversity from tank water samples for the three treatments with the relative abundances of the most abundant bacteria families (15 families). Other less abundant taxa (here less than 1%) were merged and renamed as “Others” in the pie chart. Panel B: Scatterplot of the first two axes from the PCoA of the tank water BC where the treated fish were held. Treatment is shown by colour with the 95% ellipses.
