Mean relative abundance (%) at the genus level of the gut content microbiota from rainbow trout line A in the left and B in the right panel. Each bar represents a diet * stress combination treatment within the genetic trout lines. Genera, with a representation of 1.5%, were pooled in the category ‘Other’. The arrangement of the bars is based on abundance, except for the most abundant phyla, which is placed at the bottom for legibility. The mean value joins the data for each individual fish for the corresponding treatment across the three tanks. Unstressed group (0), stressed group (1), fishmeal diet (F), plant-based diet (V)
