Abstract

Acclimation to varying salinities did not affect the preferred temperature of Saratherodon melanotheron, which had a final preferred temperature of 33.5 C. However, fish acclimated to 25 C and 0, 15, and 30 o/oo salinities had lower lethal temperatures of 15, 13, and 15 C, respectively, and an upper lethal temperature of 37 C. The thermal zone of tolerance for fish acclimated in freshwater was 17‐35 C, and was not dependent upon acclimation temperatures. Data suggest this species could expand its range in North America.
