Why are dusk, dawn, and night the best walleye hours?

Behind the walleye's retina sits the tapetum lucidum, a reflective crystal layer that bounces light back through the photoreceptors a second time — the same structure that makes a cat's eyes glow. Paired with a rod-dominated retina, it lets a walleye resolve prey in light so dim that a yellow perch or shiner is effectively blind. Low light is therefore not just when walleye are "willing" to feed — it is when their sensory edge over prey is widest, so feeding concentrates hard into dusk, the first hours of night, and the grey hour before sunrise. Bass feed when opportunity knocks; walleye feed when the light is right.
