Re: Selectivity - why and how do trout become selective feeders

Would humans do as well as the trout? :)

Re: Selectivity - why and how do trout become selective feeders

Silver,

There was a study conducted in 1973 on the conditioned behavior of trout. See A system for the quantitative study of the learning capacity of rainbow trout and its application to the study...

Wink Re: Selectivity - why and how do trout become selective feeders

Poor old fish, always getting dumped on. :) One writer said of trout "Not sufficiently evolved to burp."

Silver, you said


IMO, fish are as evolved as mammals, in that they have met the...

Re: Selectivity - why and how do trout become selective feeders

Silver,

Behavior can indeed be passed through the gene pool, if epigenetic inheritance is considered. For example, male mice were conditioned to fear the smell of acetophenone, through giving the...

Re: More on UV vision and fly tying materials in trout.

Silver,

I hope I didn't offend you in tone or words. I apologize if so, as that was not my intent.

Sincerely,
Reed

Re: More on UV vision and fly tying materials in trout.

Silver,

You are acknowledging that color is important. UVR to the trout is just one more color. The trout doesn't understand the Electromagnetic spectrum, it just knows what it sees.

If you...

It mirrors in an impressionist way, many mayflies. Below is the wing of a mayfly in reflected UV.

Re: More on UV vision and fly tying materials in trout.

Silver,

We haven't proven that any colors are of importance to trout. We know trout can distinguish color - behavioral tests have established that - but do trout use it in predation? Do trout use...

Re: More on UV vision and fly tying materials in trout.

Well, I actually have a patent on camouflage in the near ultraviolet that does not alter the visible or NIR appearance. It uses ceramic nanoparticles in a thin film. See UVR Defense Tech...

Re: Interesting read on myths

Re: More on UV vision and fly tying materials in trout.

Most sunscreens, a.k.a., sun tan lotion, absorb UV; hence they would make the UV bright areas of the Adams, UV dark.

Re: Interesting read on myths

I don't think that any thinking person will say that UVR is the sole reason for a trout to take a fly. However, as documented, the effective flies reflect UV in a manner similar to the natural...

Re: More on UV vision and fly tying materials in trout.

BigJim,

Yes, of course. For example, the Adams dry has grizzly hackle tip wings which have a superb bright and dark in the UV. The mixed hackle does as well. The body is medium-bright in UV. See...

Re: Interesting read on myths

Silver,

I wrote to Jason regarding his understanding of ultraviolet vision in trout. First, Flamarique is not a behavioral biologist, thus his conjecture concerning a mature trout's use of UV is...

I agree about confidence. I don't know why, but it makes so much difference.

I have put up a short essay about the matter of mature trout having vision in the ultraviolet. See Ultraviolet Vision...

Re: Ultra Violet Flies?

All of our flies are tied with UV reflecting materials, some reflect more than others. For example, iridescent feathers absorb most of the ambient UV, thus peacock herl is dark in the UV. OTOH,...

Re: Fly rod line rating, power, and action - an explanation.

F.E. Thomas was among the greatest designers/makers of cane rods. He made styles for every type of fishing and (almost) every pocketbook. His rods are still undervalued, IMO.

Re: Fly rod line rating, power, and action - an explanation.

Jim,

I think that we place too much emphasis on casting "power" without tying it to practical applications. For example, if you have a very stiff progressive taper rod and wish to fish streamers,...

It is also true that many of the cane fly rods being made today in the US are as good or better than any of the best of the rods made during the "Golden Age" of cane. The majority of the cane...

Re: New gear vs old

Buying used fly rods requires a pretty steep learning curve. You need to know about the history of the rod fads before buying, IMO. For example, there was a trend in the mid-to-late 1960's to create...

Re: Rod weights and Common Cents

In terms of a rod's action, the cane rod community has an advantage - the rod taper and stress curves. Looking at the rod's taper taken at 5" intervals you can determine stress curves and once you...
