Flasher selection

There’s less luck involved in Great Lakes salmon fishing success than some might admit, and the idea that every day is different when it comes to colour selection isn’t entirely reliable for those looking to improve their consistency. I believe there’s a scientific reason why certain flashers perform better at specific times of day. Here are my strategies for choosing flashers. Assumptions Before diving into colour selection, there are a few key assumptions we need to address — ones rooted in biology, physics, and the inherent limitations of how we, as anglers, attempt to understand fish behavior. The other variables: Salmon fishing often feels like a massive experiment with countless variables at play, including boat speed, lure speed, weather, barometric pressure, time of day, fishing pressure, air and water temperature, lure depth, and more. For the sake of this discussion, we need to assume that flasher colour is the single most directly-related variable to fishing success — more so than any of the factors mentioned above. Read that last sentence again. Human bias: Considering that salmon are instinct-driven creatures, it might seem unlikely that colour alone is the primary reason a fish decides to strike. Yet, as anglers, we often attribute a lure’s success to its visual appeal —specifically how it looks to us above the water’s surface — rather than considering how a fish perceives it. While salmon eyes function similarly to ours, they aren’t identical, making colour a somewhat relative concept. This is especially important when considering how colour changes with depth, as light fades and water absorbs different wavelengths. Not just about sight: Another common assumption in colour selection is that salmon primarily use sight to hunt. While vision is important, salmon — like all freshwater fish — also rely on their lateral line to detect vibrations and movement. Regardless of a flasher’s colour, its rotation creates a disturbance, and different shapes or sizes produce varying reactions. Colours shift underwater, gradually losing their vibrancy and eventually turning to shades of gray at certain depths. What I've learned As a casual angler, I used to see the flashers in my tackle box as a collection of random items— each with the potential for a magical moment. If you’ve ever struggled through a tough day on the water, you’ve probably resorted to throwing down “something ugly” or “something they haven’t seen yet” out of sheer desperation. While this might
