Glow and UV finishes help hungry predators home in on jigs and other lures.
Like glow paint jobs, UV finishes raise the bar in visibility-though in ways that are hard for human eyes to appreciate. Fish, however, see it clearly. That’s because the eyes of many predatory fish species are designed to see UV light with wavelengths ranging from 400 to 315 nanometers. Unlike color, which quickly fades as depth increases, short-wave UV light penetrates the water with ease, and scientists tell us it’s visible to fish at depths of 100 feet or more.
In case you’re wondering what lurks in the abyss that’s worth seeing lit up like a black-light poster on a teenager’s wall, fisheries biologists report that everything from fish markings to the tiniest building blocks of the food chain reflect UV light. Which means walleyes and other predators likely use these cues to home in on everything from schoolmates to dinner guests.
"UV isn’t just a deal for deep water," Glorvigen notes. "It’s a factor in the shallows during low-light periods, and in stained water, too."
In fact, Glorvigen’s UV epiphany occurred while plying the shallow, stained waters of Lake of the Woods while ice fishing with his son. "We were fishing shoulder to shoulder, using the same Northland Buck-Shot Rattle Spoons, and I was absolutely putting on a clinic," he grins. "The only difference in our presentations was my spoon had a UV finish. When he tied on a UV Buck-Shot, his catch rate soared."
