We investigated the structure of interindividual variations in the diet of brook charr (Salvelinus fontinalis) based on stomach contents data of 3776 charr captured in 69 lakes of the Canadian Shield (Québec, Canada); 29 of these contained allopatric brook charr populations, 24 contained brook charr and creek chub (Semotilus atromaculatus) and 16 contained brook charr and white sucker (Catostomus commersoni).
