Ultraviolet has as much to do with fish vision as color. We (humans) don't know all of the ways they use it and see it, but they do. Losey Labs in Hawaii is doing research on just that.
Leaders that YOU think are clear are like lazers to fish because of what they reflect in the ultraviolet spectrum. And not all fish are equally set up to see UV light. Fish actually secrete UV absorbing or reflecting mucus (their slime) as required for day and night visibility or invisibility, or for breeding, identification, feeding, or evading predators. Depth of water is also a big factor in color perception. A fish that is a solid color to you may have specific UV patterns perceptable only to other certain fish. Contrast is more important than color, as is the 'strike image', or the profile against the background. That's why reflections are important, and sound, and movement. Some lures that you can see in the water are invisable to the fish. That's why black flies and lures work so well. If you want more info, let me know.

They have a whole chapter on fish and their ability to see colors. Can't remeber what they said. It is an excellent read though! >>> [EMAIL PROTECTED] 08/30/02 01:54PM >>> Do fish see colors? ? ? I've been told that fish do not see "in color." Fish see RED as a GREY. I guess that makes BLUE a GREY also. So what about GREEN, BROWN, YELLOW and all the colors we have in fly tying material. Are we just mixing and matching GREY's and shades of GREY ? ? ? I think birds see in "color" and I think primates see colors-so what about fish? ? ? Kinda makes me think-any ideas? ? ?
