Native Chinook salmon Oncorhynchus tshawytscha and non‐native brook trout Salvelinus fontinalis prefer similar water temperatures

Preferred water temperatures and acute temperature tolerance limits of two salmonids in California were assessed: juvenile Chinook salmon Oncorhynchus tshawytscha , a native anadromous species, and sub‐adult brook trout Salvelinus fontinalis , an introduced game species. These two species preferred similar temperatures across an 18 h temperature preference experiment and showed similar critical thermal tolerance limits, suggesting a substantial thermal habitat overlap in the wild.
