You woudl be surprised how many UV lures you already have. I went out in my warehouse with a blacklight and about 75% of my lures light up like a Christmas tree. Funny thing was, I saw some not light up that I woudl have been 100% sure would have been UV.

I had this conversation with Dr Bruce Tufts, Tufts Lab Queens University Kingston Ontario
Following is a summary of our emails from about two weeks ago

Do i correctly remember that at a Muskies Canada meeting in Gan about 2 years ago that you told us that fish couldn't see UV light and did that apply to all game fish or just esocids.
I also recall you saying that a fish couldn't detect odor unless it was water soluble making oil based scents a waste of money is my memory correct
Bruce
Hi Frank. You have a great memory. I did tell you that gamefish can't see UV light according to research on that issue. Correct on the other point as well. Scent needs to be water soluble to be available to olfactory (smell) receptors. Both issues are discussed in a good book called Knowing Bass by a fellow who was a scientist for Berkeley...To my knowledge, they are also the only company to do any real experiments on their products.

Thanks Bruce does that apply to salmon and trout ? Salmon Anglers seem to THINK it works for them but I'm wondering how far UV light could even penetrate. So are their lures getting a strike for other reasons eg. vibration? I know I could get a reaction strike from a muskie on a socket wrench with the right location and timing. I will have to see if my library can order that Knowing Bass book for me. Thanks Again
Bruce
Hi Frank. I'm pretty sure it does also apply to salmon and trout. I'll do a quick literature search in the next couple days since it has been a while since I've talked salmonids. I totally agree with the socket wrench comment

I did a bit of a search yesterday and a couple of articles suggested that salmon and trout could see UV at the par stage and when they smolt lost this ability probably like us to protect the retina. I also wonder how much UV light gets to the depths.
