Abstract
This paper investigates the thermal tolerance of the three strains of brook trout that are the primary ones used in Ontario hatcheries, as well as that of a brook trout subspecies. Evidence for significant differences in temperature tolerance was observed both within and among strains, suggesting that the thermal performance of brook trout populations will be under substantial selective pressure due to climate change. Strains with existing tolerances for warmer conditions will be better suited to handle anticipated warming temperatures.
