Fly Fishing: Stalking Trout

Unless you are fishing gin clear spring creeks and attempting to spot holding fish you, like me, are probably moving about a stream looking at probable holding water based on currents and structures in the water. We know not to wade carelessly and maybe we consider the finish on that fly rod (maybe a matte finish) or not to wear to flashy of clothing. We do have a sense of a trout’s vision and sense of vibrations.

Today, I am sharing some basic info for the beginner or a refresher for others about a trout’s senses and how to move against those senses.


Trout: “I feel your vibes….”

The wary fisher knows the fish often see the approach, the waving fly rod, the ripples on the water from the splatting fly line or leader. And, we even have an awareness to wade slowly and quietly because the fish can ‘hear’ us?

Much like our own senses can combine to alert us to subtle changes, the above trout can detect changes about it that alert the fish not just to food but to predators….in particular us.

The lateral line is such a sense that allows fish to feel a presence than could be a food source or a threat, as well it aids the fish in navigation.

About the Lateral Line
Trout have inner ears, which allow them to hear sounds as we do. They also have lateral lines, special sense organs used to “feel” sounds. Lateral lines allow trout to hear sounds that are too low for humans to hear. Every trout has two lateral lines, one on each side of its body. A lateral line is made of a series of U-shaped tubes. Every time the water outside the U vibrates because of a sound, a tiny hair at the base of the U wiggles, which sends a nerve signal to the brain. The trout’s brain translates the wiggle into information about where the vibration came from. Trout use lateral lines to find food, escape predators and keep away from obstacles.’


Trout’s Lateral Line & Blushing Beauty

The lateral line, visible on the trout is for what? The usual explanation is it allows the fish to sense movement of ‘prey’ in order to avoid risk or find food. It also allows the trout, or other fish with a lateral line, to sense water pressure, which helps the fish know depth, location relative to other fish and objects and maintain their position in a migratory school.

Some studies suggest that a lack of vision (chemically induced in lab) is less important to the fish than a less efficient lateral line. The lateral line is the eyes, ears and remote touch in one placed wedged between beautiful dark olives and silver/white bellies.

It’s all more complicated than I muddled through, but again easy on that fish, when handling…nice and gentle. No squeezing, no holding it ever through/under the kill plate like some goofballs do, and again no dry hands or rough nets.
