We present a model that accounts for the variety in observed relationships between temperature preference and acclimation in fishes. The preferred temperature is that temperature at which Fryˈs scope for metabolism is maximized. Thermal acclimation shifts the temperature for maximum scope in such a way that Zahnˈs types of temperature‐preference acclimation correspond with Prechtˈs types of metabolic compensation. The model predicts that fishes exhibiting Prechtˈs “partial,” “no,” and “inverse” compensation prefer temperatures that are increasing, independent, and decreasing functions of acclimation temperature, respectively. Experiments with bluegill Lepomis macrochirus and blue tilapia Tilapia aurea , together with information from the literature, provide support for the model.
