Fish Vision & Color (Variables of Color for Streams and Stillwaters)

Water, however, presents a serious challenge for fish and fishermen when it comes to vision and color. Many characteristics of light quickly change as it moves through water. The first thing to realize is that the color of your fly in the water is almost always different from what it is in the air. I have to be a little technical to explain this, but I think if you bear with me, you’ll have a better understanding of how fish perceive color and how this impacts the flies we tie and use.

Absorption also restricts how far light penetrates into the water. At about three meters (about 10 feet), roughly 60 percent of the total light (sunlight or moonlight) and almost all the red light will be absorbed. At 10 meters (about 33 feet), about 85 percent of the total light and all the red, orange, and yellow light have been absorbed. This has a direct bearing on how a fish perceives a fly.

It should now be clear how the depth of the water or distance from a fish affects the visibility of your fly. In extremely shallow and very clear water, colors may look similar to their appearance in the air; as your fly gets just three feet deep or three feet away from a fish — or less if the water has limited clarity — the colors will start to change, often with surprising results.

streamers, leeches, bombers (articulated or hinged or trailer…some history)

Black Heron Fly Fishing

Black Heron Fly Fishing

Not too long ago I received some questions about tying Articulated Leeches. I knew a little about the popularity of these flies due to their success in enticing strikes, but I was in the dark about how to articulate the two hooks. It prompted a little research on my part to find some hsitory and methods for tying these flies. What I found was a bit confusing, however, and I really didn’t like the methods that I discovered.

So, it seems that there are many methods used to tie connect the hooks for these flies. The underlying principles behind all them are strentgh, action, and anti-fouling. Obviously, when you are fishing for heavy fish in fast water, the concern is that with two joined section of hook shank, you do don’t want to lose a fish due to a weak joint. The purpose of the articulation, in the first place is to add life-like action to the fly, so that it entices fish to strike, believing it’s the real deal. And finally, the joints need to be tied in such a manner that the rear shank will not double back and get fouled with the front shank, ruining the action that the articulation was designed to impart. If all of these characterics are present, combined with the right pattern color and size to match the conditions, these flies can be unbelievably deadly.
