Canonical correspondence analysis (CCA) for the gut bacterial A and fungal B composition comparisons between rainbow trout fed the three different diets (FOM, FMR and FOR) for three months (n = 6 fish/diet); FOM: commercial diet including fishmeal and fish oil, FMR: fish meal replaced with plant proteins, FOR: fish oil replaced with rapeseed oil. Fish meal, plant proteins, fish oil and rapeseed oil were the four different components of the three diets and were regarded as factors to analyze correspondence with the 20 dominant genera from gut bacteria and fungi. Note: g_Escherichia is the g_Escherichia-Shigella
