Critical Thermal Maxima of Five Trout Species in the Southwestern United States

Abstract
Critical thermal maxima (CTM) and responses to fluctuating thermal regimes indicate that adult rainbow (Salmo gairdneri), brown (Salmo trutta), and brook (Salvelinus fontinalis) trout species, introduced into the southwestern United States, are as well adapted to elevated water temperature as adult Gila (Salmo gilae) and Arizona (Salmo apache) trout, which are native to that region.
