Evaluating the scotopic visual sensitivity of walleye (Sander vitreus) and implications for foraging habitat

Understanding the physiological limits of visual detection is essential for delineating habitat use in freshwater fishes. Walleye (Sander vitreus), a crepuscular predator with well-documented low-light foraging capabilities, exhibits visual adaptations suited for dim environments. Using electroretin...
