In this eye-opening edition of The Parsons’ Perspective, Captain Lee Parsons dives into the complex world of underwater optics. Understanding how fish see is a fundamental skill for any serious angler. However, Lee explains that sight is only one piece of the puzzle. To truly master the water, you must understand how a fish balances vision with its other powerful senses. This knowledge allows you to choose the right lure for the right conditions every time you leave the dock.

The Impact of Turbidity on Vision

According to Captain Lee, a fish’s ability to hunt depends heavily on turbidity. In our local waters, clarity changes constantly. In very clear water, you might assume fish have an advantage. Surprisingly, Lee notes that even in clear conditions, fish often do not truly “see” the lure until they are quite close. Their vision is optimized for movement and contrast rather than fine detail. When the water gets murky, their sight radius shrinks even further, forcing them to rely on more dependable senses to find their next meal.

The Role of Hearing and Feeling

If they can’t see the lure from a distance, how do they find it? Lee emphasizes that hearing and feeling are the primary ways fish navigate their world. They use their lateral line to detect pressure waves and their inner ears to pick up sound. This is why your topwater presentation is so critical. Some days, fish are attracted to high-pitched rattles. On other days, a low-frequency “thump” is the only thing that will trigger a strike. Lee suggests that you must treat your lures like a musical instrument.

Building a Pitch Arsenal

Because fish preferences change daily, Lee advises having many pitches in your arsenal. You should never rely on just one type of sound or vibration. Experiment with different rattles and popping sounds until you find what resonates with the fish that day. By matching the sound profile of your lure to the water’s turbidity and the fish’s mood, you increase your chances of a hookup. Remember, a fish lives in a world of vibration; if you can make them feel the bait, you don’t always need them to see it.
