I hope you all have a great season, it is 70+ degrees outside in NH; Spring approaches.

All the best,

Well, I suppose that's also a way of avoiding having to prove anything.

The challenge, which you also avoided answering, stands;

QUOTE
Name or describe three flies that catch more fish as a result of some UV related factor known to you and for which you have evidence.

Name or describe one fly which has been designed using such factors that is successful. Preferably one that is MORE successful than another without these factors being taken into consideration and used in the same circumstances.

Okay, since Mike has said all he is going to say on the matter - and he is a man of his word - I find myself somewhat re-invigorated.
Otter, is there any more info you would like?

Regards,
Reed

Please pardon my intrusion into what is a very interesting conversation.
I've held back on asking a question. I've been waiting for the swing to come and include it.
I read where, and it was only briefly, the terms of stained or off colored water..... Yep, has a impact on the variations used.

Yet no one has mentioned the effects of the river/lake/pond/body of water's bottom and the various odd bits of things
(turbidity), have upon the way the light is reflected back towords the surface and how that inturn bounces the light rays all over the place
and it's effects on the coloring of the bug or fly.
So far, mostly, the talk has had to do with the light from above. Or at least that is the gist of what I understand from what I've read.

Perhaps ya'll can help re-direct some illumination in that direction as well ????? I've never been one to anyalize much of what I do from day to day
let alone approach fishin' (fly or otherwise), with that amount of intensity...

Thanks for your musings...

hank

I asked the above eariler in the discussion.
Have you any thoughts on the matter ?

Again any and all musings are appericiated...

I have said all I am going to say on the matter to you. That has no influence at all on what I might say to somebody else. I am well aware of the various tactics used to avoid answering something because you have no sensible answer, and others here will also be well aware of them.

Quite apart from any UV related matters, trying to bs me wont do you any good.

Have a nice day.

This thread went from some what rediculous to hilarious in a couple posts! :lol: :lol: :lol:

Funny stuff overmywaders! ;)

Hi Mike,
Perhaps you are being too technical . What Reed is saying and has documented is that many of the "most effective" Dry Flies from Whitlock's 1984 book have UV reflectance. So if one accepts that Trout do see UV as Reed and others believe, it would be logical that flies that exhibit some uv reflection would work better than those that do not. They are reflecting the uv that is in there given environment, just as the naturals would. Would they reflect it exactly as the naturals? No, but they could be with the right equipment, but while that would perhaps create a more killing fly, it is not necessary I would think as long as the tied fly had SOME uv reflectance it would be beneficial . Obviously total UV reflectance would be unnatural. Hypothetically think of it this way: You have found a selective feeding trout you have identified the insect that the trout is feeding upon. You make your fly selection based upon size, shape, colour and (translucence effect+ now UV reflectance+ motion effect/illusion + other such variables) that can be called the "appearance of Vitality" or "Vitality". As the fly approaches the trout, the fish makes it's decision whether or not to accept the fly as food or not. With Presentation et al. being the same, would you rather present a fly the reflects some UV or a fly that does not reflect any UV at all, when both flies appear to be the same in every other way?
I look at the UV information as this: "Interesting! This would be cool if it works! I think I will find out if it works by tying up some flies and see what happens, then refine the flies as I learn more about what I am trying to achieve. If this UV thing is bogus I will find out soon enough and I won't waste anymore of my time with it. How does the UV thing corespond with my go to flies that always seem to work? Is there a corelation? There is ! Wow imagine that! Let me tie up some different patterns that use the same principles and or materials. Do they work? Bingo! This is cool!"

Hank,

Good question. While the research I did was on trout in rivers, other fish in other environments did appear as well. For example, the carp is known to have excellent UV vision, yet it lives in chiefly a turbid environment. UVA penetrates clear water very well, it has been documented in viable amounts at a depth of 600m in the ocean (1800+ feet). However, UV is also susceptible to scattering due to particulates. The result in turbid water is that the UV provides a background illumination. The fish can use this light (UV) background to detect UV dark objects. Here is an example:

Does this help at all? I don't know what the exact conditions are you are describing.
Regards,
Reed

BTW, Dr. Cronin also liked my book, as did Dr. Hawryshyn. The detractors have been those who have not read my book, but somehow know that it is all wrong. (no emoticon covers this human aberration)

Anybody can believe whatever they want to believe and try anything they like, regardless of the whys and wherefores. However, if you want things to work well you would be better advised to base your trials on reality, and not on wild speculation.

There is no proof that trout can see in UV wavelengths. If they can not, then all this is completely irrelevant in regard to artificial flies anyway.

Mr. Curry assumes that they can see in UV wavelengths. Indeed, some of Mr. Curry's other assumptions are also quite breathtaking!

Unfortunately for him, even if he is correct in his assumption that trout can see in UV wavelengths, he is completely unable to provide any correlation to artificial flies or even natural ones.

There are so many holes in this so-called "theory" that it is basically laughable. It can not even be called a theory, because no proof or reasoning is given, just a lot of unconnected facts about various things.

There is no evidence at all for any of it. The only evidence at all is against it. I am quite amazed that so many people would even take it seriously at all.

Whatever. I wrote what I think about it, and people will doubtless make up their own minds. Doesn't make any difference to me. I am not trying to sell anything connected with it.

Indeed, if somebody had found some effect like this that affected how well flies work I would embrace it and use it immediately. This was the only reason for my own research in this direction. I found nothing useful in regard to artificial flies. Neither has Mr.Curry. If he had he could simply say so. But he avoids answering any direct questions on the matter, and proceeds to dole out more unrelated information.

Not my problem.
