Ultra Violet Light and lures

So I have been reading about Ultra Violet light. It is a series of colors that are of a wave length that is said to be invisible to us. However, animals and fish ( crappie are fish ) can in fact see this spectrum of colors. We see visible blue but not UV blue, they see UV blue and maybe not our visible blue. The first I learned about all of this was decades ago reading about washing camo clothing. Tide detergent adds UV brighteners to make clothes appear cleaner than they actually are. Your white shirt is actually dingy white, but with the enhancement the shirt looks really white. Adding Tide detergent to the machine when washing camo adds these brighteners to the camo, rendering it quite visible to deer and birds and fish of course. The deer cannot see blue but the hunter wearing a Tide washed camo jacket will glow like a light bulb.

One of our wedding gifts was a collection of uranium plates and glasses. They belonged to her great grandmother and they are green, but when a UV light source hits them they glow like, well like they are radioactive green. We don’t eat off them, they are just for looking through. Anyways I am shining this light around the house and start seeing other things that glow. All manner of things have these UV brighteners added. They get added to make the things catch our eye so we will buy them.

Anyways, I was practicing jig tying and was using plain unpainted jigs no collar and powder painting them with a bright orange that contains UV brighteners. The idea is that visible light sources, such as the Sun can only penetrate water so far. Murky water limits that depth even further. UV light penetrates much deeper. So in theory, something coated with UV enhancements could still be visible to fish even when it is deeper than the visible light can reach.

I was wondering what you guys know about crappie and UV enhancements. They seem to shun the light of day. Small creatures emit UV coloration which can be seen using a UV light source. Tomato caterpillars ( horn worms - the larva of Hawk moths ) glow as do scorpions. I am thinking crappie might be tuned in to this UV spectrum, and that is why they move away from visible light. Remaining in sunlight might reduce their UV advantage, if they have one. Plankton and such emit UV colors as well.

I bought some things to test UV out. A UV oil from ProCure. I selected one that contains no scents so I could mix it with my Slab Sauce. I have this mixture in a tightly sealed jar that I can dip jigs down into. They claim it works by making the lure more easily seen by the fish. Some swear by it, but I am not so sure.[ I tried the squirt bottle but missed and made a mess.]

After I tied up a jig I hit it with the UV light to see how well the powder paint glowed. Well I was surprised to see this.


Attachment 396808

The powder paint glowed, but look at the chenile. It really glowed.

Attachment 396809

This is chenile ( balled up in package) next to some yarn that I bought at Walmart instead of buying chenile, which is kind of pricy. Big spool for a few bucks and all sorts of neon colors and they glow. The yarn glows even brighter and I have enough to last forever.

So all of this made me curious and I just had to ask you guys about all of this UV light stuff. Does it make a difference or is it much to do about nothing much ?

Oh and I like that the yarn sucks up the slab sauce real well. I need all the help I can get.

This has been discussed many times on here thru the years...I just used the search function here on the site and found you several pages of threads to look at about it. Here is a link to them...click on this... https://www.crappie.com/crappie/sear...rchid=33500600

That is really interesting. I never thought of that before. Actually, I can’t get past the uranium dinnerware! What could the manufacturer have been thinking? Long before folks knew how dangerous that stuff can be. Is it safe in your house, although I realize it has sentimental value.

got no clue on if it works better and can be seen better or not ,but I have had baits that were UV enhanced and some seemed to work really well .
we used a black light at night before anyone even thought about using jigs at night back in the 70eez on lake Fork when it first opened ,with a black and chart tube jig and MAN did the skirt glow and the fish hit it .....:highfive
uranium plates ? that is for sure something I never heard of .......:dono

Glad to see you are feeling better. I apologize if my eagerness to learn has run afoul of normal operations, but the search feature does not really assist me much. I end up with tons of threads that have nothing to do with what interests me. The system finds posts that only contain one of the words, as you know. I thank you for attempting to assist but even that did not work, the link doesn’t work. So off I went searching the web for details into what crappie might actually see.




First off we know that light is made up of waves. From left to right on an imaginary chart we have:

Gamma Rays- X Rays- Ultra Violet - the visible light spectrum- InfraRed- Microwaves- Radar

There are some others but of all of these we are only able to see the visual spectrum. It is further broken down into, from left to right:

Violet - Blue - Green - Yellow - Orange - Red

As visible light penetrates water the waves get absorbed, and at about 300 feet none of the can reach any longer and total blackness occurs. The depths at which each color stop relates to the wave length, with red and it’s longer wave lengths fading first. Now that doesn’t mean that an object painted red becomes invisible, it means that the object no longer looks red. Might appear grey. Then next to fade away is orange, then yellow, then green, then blue, then lastly violet. Violet light can penetrate further than all the others because it has the shortest wave length of the visible colors.

Now Ultra Violet has an even shorter wave length and can penetrate downwards even further. This is what interests me. If I am fishing in murky waters and light is being limited by sediment and such, I am looking to use lures that have colors the fish can still see. So in muddy/ silty waters I would do best with black lures. In water stained by tanic acid from pine trees, the darker colors are also a better bet. In green algae waters lures that are two toned would be most easily seen. This is all because of contrast though. The dark colors stand out. The lure completely lacks detail but the overall shape can still be seen and the fish can swim over and grab it. Same thing with UV lures, they offer that contrast when normal colors can no longer do that. Pretty sure anyways.

All of this is completely affected by conditions of course, such as sunny days vs cloudy, the angle of the light, and water clarity, etc. On bright sun shiny days shiny lures can get noticed more easily because they produce flash. Minnows flash as a school swims by so that is the attractant there. However on cloudy days the blades really don’t flash all that much, so a better choice would be something that vibrated and has an ultra violet flash to it. Ultra violet light can better penetrate AND is more prominent when visible light lessens. You may have noticed what I call the magical moment. It happens when the Sun first sets. As soon as the Sun’s rays stop reaching our eyes directly, just before it starts getting dark, the ultra violet light becomes more prominent and everything kind of glows. Your skin color changes for example. It only lasts for a few minutes at most, but you have seen it your entire life. Colors change because the ultra violet light is affecting the colors. So during cloudy days, early morning, early evening, UV colors are still available to be seen by fish.

There are also other issues and factors of course, such as distance from the object. In the beautiful springs surrounding my area I can snorkle down underwater and still see someone at a great distance because of the crystal clarity. Obviously dirty water would inhibit that, and lessen the distance, as there would be suspended particles blocking my view. A fish has to deal with this limitation as well, and uses his other senses to assist. He might smell something to eat, like we smell bacon on the stove, and knowing the baitfish is there, swim over to get a closer look. He might feel vibrations from the creature he wants to eat and can locate it using that sense. Either way though those just get him closer to the object so he can see it. Maybe he will have to get right up on the object before he can see it, and if he does, he does.

So according to what I have found on the web, there are some clues as to what colors of lures I might begin my search with. I am certain that many of you already know all of this and have expounded on it many times, but this is all new stuff to me, so bear with me here. Surf fishing meant I was chucking bait, not lures, well other than surface lures. I would set up in a likely spot, and the fish found my offerings, I did not have to chase them down and show it to them. I did use colored beads and such as enhancements, but I cannot say that any particular color worked best. Black was a favorite and now I am understanding why. The surf is full of suspended sand and sometimes mud, and dark colors show better under those conditions. I applied UV to my painted sinkers, but never attempted any sort of study about them. I even made glow in the dark sinkers. LOL

I intend to keep reading about what fish see and trying to discern what a crappie might see, or not see. So far if I was fishing in clear water on a sunny day I would want a shiny spinning blade to sparkle as I went along. Perhaps a bright color or a light color such as white or silver or chrome. In muddy water or on heavily clouded days I would want something that is dark, for contrast. It might be nice if it had an odor to it. Might be nice if it created some sort of vibration or sound. Might be nice if it had a UV color that could be seen by the stupid fish.

I was amazed at how many objects in my home have a UV component to them. Even the dumb dog toy glowed when hit with the flashlight. People use them to see dog urine and catch the little guy, and thankfully neither of my dogs has a sneaky habit. Caribou can see wolf urine as it puts off a UV glow. There are all sorts of instances where fish are using UV light to recognize food items, and mates. Butterflies use UV light to better see flowers. Black Eyed Susans give off a UV flash from their flowers to better lure in insects to pollinate them. Cops use UV lights to spot body fluids on homicide victims, and even to collect fibers and such as many contain a UV enhancement. I shined it on the floor under my fly tying desk and saw all manner of small fibers and such.

There is a reason crappie like to hide from bright sunlit areas. It may be that the bright light hurts their eyes, but it might also be because they loose their big advantage in visible light. That the prey items get a little quicker jump when they make their approach, because they can see the crappie earlier. That once the visible light goes away there only remains UV light, and that makes for good hunting. We all know predator fish bite our lures best in first light and last light. Scientists tell us that is because all the baitfish have issues with their eyesight adjusting to the change in light. That predators can adjust quickly, and they have figured out that it is easier to capture baitfish during these times. Get the little devils while they still cannot see what is coming.

Let me write that again- It is easier for bass and crappie to capture minnows during the periods when the light is changing, early morning and early evening, because their eyes adapt faster and that offers and advantage. Who knew that bass and crappie had figured all that out ? I thought it was easier to catch bass and crappie first thing in the morning because we could hook them when they yawned. There is a whole world out there to be discovered and I intend to learn as much as I can. If you have something of interest, please share it with me. There is nothing that I would consider too dumb, and this is a very friendly site, so....... let’s have it.

The plates.....you are interested in the plates.

Apparently back in the roaring 20’s these plates were high fashion. Her great grandfather bought his lovely wife a set so she could show off. They really were a luxury item. Anyways they are not dangerous to eat off of, but could be should I happen to break one of them. So for my health we leave them in her antique ( I bought ) currio cabinet thingie. They are not for eating- just for looking through.

Here they are lit up by the UV light.

Attachment 396832

We see them in antique stores all the time, but almost all of them are fakes. I don’t know much about them, only that she is always looking to add to her collection, and refuses all but the ones that I refuse due to expense.

I appreciated the story from the 70’s fishing at night. I always wondered how fish could see at night to eat like they do.

About 15 years ago while walking through my son's room I spied a blacklight and borrowed it to see what some of my favorite jigs looked like. I was amazed at how bright the jigs were. I figure that since I see it better than fish in muddy water or low light conditions could see it better as well. When Pro Tec came out with their UV Blast I started mixing that into some of my powder paints and the difference was huge, much brighter heads. Fish need to see the bait before they eat it and I feel they do see it better and I've caught more fish since I started doing this. For crappie my best colors have at least two uv colors in one jig. Dirty water is when these baits shine. I'm a true believer that these baits will catch more fish in the murky, muddy lakes I fish than jigs without the color enhancements.

Sorry....you have not run afoul of anything. I was just trying to help you get some information. I do not know why the url link I gave you does not work for you....i just tried it on my phone, my table, desk top , and lap top and it works for me. Any it had three pages of threads and half of them were on subject with some good discussions. Personal experience with baits that glow....i really did better without them....i think they scared the fish...or perhaps did not look right to them. But that's just me...some people loved them.

Well thank you for the effort anyways. It says nothing matches. I use an IPad Pro and it probably doesn’t like something. I would love to read more about this subject. It did occur to me that it was possible that instead of attracting crappie, it scared them away. If that is the case using a light to eliminate everything treated with UV enhancements would be good. However, Jim here thinks it makes a big difference and I do like his stuff. I trust that he too has good experience to draw from, even if I have to guard my wallet when I get to looking too close at his creations.

I plan to go with as much UV glow as I can get on two jigs, and no UV at all on two jigs. That way I will be able to draw some sort of silly and completely useless conclusion regarding all of this. The world’s best discoveries were simply stumbled upon, but the key factor was the willingness to be observant. I always felt being observant made me a better surf fisherman, and I am sure it will make me better at this little game as well.

Thanks for the replies. Anyone else ?

As with all things...the main thing is ...learn...experiment...have fun and enjoy yourself. And now that link does not work for me :banghead

I have a couple uv flashlights on my desk all the time. When I go jig tying material shopping I take one with me and even check tying thread to see how it looks. Favorite color thread is Fl. orange that looks red but is much brighter than red under uv flashlight. My favorite hair the past few years has been opossum and bought several skins. I had two cut into crosscut strips for my bass jigs. Under uv light some of these baits have a pale pink color instead of bright white which is interesting, possibly from the tanning process. Whatever the reason, they catch fish and that's what is important.

Interesting and good thread. Thanks!

I was out at my favorite spot fairly close to the house last year and an older Gent and I got to gabbing about tying jigs. He mentioned back in the day,( he was well into his 80's), he remembered tying jigs with opossum hair and doing very well on crappie. I had never seen him their before, or since. Figured I would give it a whirl and see what happens. Thanks for reminding me about the opossum hair jigs....

I've tied quite a few with possum hair and they work great.

While using my UV light to cure resin today I noticed some of my plastics really shined up. I can imagine that those baits, while brightly colored, may be UV reactive.

Could be but bear in mind that flourescent colors will shine with that light, even though they might not actually be UV reflective. That light is catching enhancers added for brightening or whitening perhaps. Paper has these and is not UV reflective..... I don’t think. However if those things were UV you could find all manner of things to use. Thanks.



So I bought a mold to make Bell sinkers and poured a few- 1/8-1/4-3/8-1/2-5/8-3/4-1.0-1.5-2.0 ounce sizes. Real pain to position brass eyes though. I use these for my rigs being pushed out the front. There is a clip on the end of the main line that captures the sinker. The jig’s leader clips to the sinker eye as well and that clip is small and sports a small swivel as well. When the fish grabs the jig, those two clips act in a way that helps transmit “BITE BITE” to the rod tip.

I fished Wednesday and only caught six, but they were strong bites. I did see a few small bites that I missed though. I was using 1/2 ounce sinkers and could have used 3/8 instead, and will next time if I can. The rods handled the fish no problem.

So I powder painted my sinkers. I used to make highly specialized sinkers for surf fishing, and invented a few along the way. Maybe made 10 thousand or so. Anyways these sinkers require you to grab the sinker and reset the grip legs every time you bring it back in. One day I was on my way back home and stopped and bought a Whopper to eat. Halfway through the burger I noticed this grey coating on my fingers. I did not finish the burger. It was lead oxide residue transferred to my fingers, being transferred onto my sandwich, and into my gut. Needless to say I wanted to do something and that was when I learned how to powder paint. I did it more to keep lead off my hands than anything else.

Fingering these up Wednesday also left lead residue on my fingers. I saw it. So I been painting them to gain a barrier between the lead and me. I dipped in plain white then clear with UV additives, and then baked them. White will increase the reflective ability, as it does with Glow in the Dark stuff as well. They came out white glowing a beautiful blue.


Attachment 397209

I did up all but the 1/8 size. Because the inscribed size numbers are hard to read I used a Sharpie.

Next because I also like to pull jigs behind the boat, I bought some trolling sinkers. These came in 1/4-3/8-1/2-3/4 ounce sizes. These I dipped in plain white, then an orange, then the clear with UV enhancements. I was showing it to my wife when the Magic Moment happened, when the visible light is fading away and UV becomes dominant. She grabbed her dish and set on deck railing next to my sinker and each glowed like crazy.

Attachment 397210

I also found a cool crank bait. Rapala Shad Rap Jointed size 4 in ultra flourescent colors combinations with.....wait...wait for it....UV enhancement. These were cool. Very bright flourescent and a great action. Best dive is said to be about five feet.

So Wednesday I put two lines with jigs way back behind the boat, and two much closer but with sinkers involved, and two crankbaits. The jigs accounted for half my six fish total. I like the idea of using weights instead of long lengths of line. Probably tougher dial in, but definitely would be easier to land the fish. I kind of like surfing them along.

I also managed my first fish on a jig that I made, well tied.

Attachment 397211

I think that he and two others were more interested in the smell than the details as offered. The Chenile soaked up the Slab sauce I am figuring.


Attachment 397212

Released like the others were. I noticed the osprey always visit me from behind. They check out to see if I might have tossed a fish out back there. Clever birds.

Attachment 397213

Attachment 397214


I also acquired a Do It Pony Head mold in 1/16 ounce-six cavities and another 1/8 ounce size cavities. Going with willow leaf blades and a wide gap jig hook to try to gain a little advantage with hook ups. I figure these will troll nicely, and done up with chenile and Slab sauce...well.

I also ordered Pawzke’s crappie balls in the blue shad style. I couldn’t help myself.




Saw this on the way to the lake and thought you might be interested. Took picture at highway speed. Couple of whimps here.

Attachment 397215



Anyways I am gonna have at this UV stuff some more. Let me know if you have and ideas or suggestions for me to test. So far the fish have been sparce for me but that is because of all the other issues I have to work through. LOL

There is a special extra thrill when you catch a fish on your own creation. I have all my stuff but it has been years and I need to clear a space big time before I could even think of setting up. It is a fun hobby.
Bob
PS The shot of the line worker on the hi T line is good, but I think one that I have seen of the guys that have gang saws hanging from a chopper and trimming trees along the utility right of ways is even scarier. Both are pretty crazy, and whatever they’re charging probably isn’t enough!

Very nice

I totally want some uranium dishes now....:Rofl

Do you have a pic or brand name of the UV yarn you bought at Walmart by any chance?

Defiantly taking my UV light with me on my shopping spree's from now on. Even if I'm not necessarily looking for tying materials, I can spot check on some things as I go from one area of the store to an other, and sorta purposely pass through the sporting goods and craft section on a detour from the can goods isle to the meat section...lol...

It was a large roll with about 8 different neon colors for a couple of bucks. I like the stuff for chenile because it really sucks up the Slab sauce. I also used the chartreuse yellow to mark my rods for lengths. They came with markings, but I don’t see them when needed. Now can’t miss seeing them. And a piece of pink and one yellow indicate which life vest is mine and which is hers.

Thank you for your contribution

I wonder if it is the same yarn I already have then. I don’t have a light to check but the yarn I bought was several colors together.

Attachment 397288

And by the way the yellow from this yarn was on the jig as tail material when I caught my PB! I also have some bright green yarn that’s pretty as well. Thanks for sharing

Yeah looks close to what I have.

So yesterday I was out on a local lake at O’ Dark Hundred. The sky was overcast and there was some fog about. Kind of gloomy like Transylvania. Anyways I get the first rod rigged and as I stretch it out in front of me preparing to place it in the holder, I noticed the sinker. It was glowing like crazy from 16 feet away. The white paint and UV Blast combination leaves me seeing a faintly purple color. They really stood out. I didn’t think to take a picture- sorry. I did lower one of the sinkers to just under the surface and it was still obviously glowing underwater. No idea how deep that continued but most all of my local lakes are very shallow anyways.

So.... on bright sunny days we get UV reflections, but we cannot see these colors being reflected off certain objects because the visible light is dominant. Visible light is the 1,000 pound gorilla in the room. We see greens and reds and blues because they are more intense. However, when conditions change and visible light lessens we are able to begin to see the UV reflections. The treated objects appear to glow. So we can figure this effect works underwater about the same as it does above water. Be small differences, but when visible light lessens, UV light can emerge.

So....UV light is reflecting all the time, but only during low light are we finally able to see it.

Predator fish are most active during first light and last light conditions. I suspect this is so because they are able to use UV light to their advantage. Apparently it is quite an advantage as well. Guessing here, but I suspect it allows them to better see exactly where the minnows are at. Perhaps it even allows them to approach closer before being spotted by the minnows making it easier to capture them.

I do not think UV light is the be all to end all, but it is certainly something that is readily available for us fishermen to use. There is something to all of this. It is up to us to determine how we can exploit the sources of light available. We know flashy sparkly things work on bright sunny days in clear water.....well UV light works when those conditions are not dominant. The less sunny the more important UV becomes.

During regular daylight we see....

Attachment 397377

When regular daylight diminishes we see....

Attachment 397378

We know that some fish use UV light to identify mates and find food, and there are insects and mammals that are adapted to using UV light. Makes sense to me that some species learned how to exploit what is naturally in their enviroment. The really big question is....can we figure out how to exploit it.

I have read and watched videos where, at times, the really bright light emitted by the straight painted jigs have made fish turn-away. I wonder if maybe adding non-UV paint to it might dull it down and make it appear more subtle, maybe more natural to the fish...

Good thread. One thing for sure, you never know what they’re thinking!
Bob

Well I am going to test my UV stuff again tomorrow.

Found all manner of tackle here at the house what already been treated with UV enhancement. Who knew ? Like a standard almost. I mean if you are opposed to using UV enhanced products, due to belief or practice, you would do well to buy a real UV light source and check everything because I am telling you it is in everything. Many lures contain these and there is no mention of it in the description.

Makes me wonder why someone would add something special into something they know someone is purchasing for a very specific task....and not bother to mention to them that the item contains this particular enhancement. Scents are usually mentioned, but I looked at the descriptions for many of the things that I have purchased, and nothing about the enhancements that my light is proving to be present.

If it was not for me being able to see UV light colors when science says I absolutely cannot.....well it wouldn’t be of much interest really. The fact that I can see my sinkers and lures and dishes glow in low light conditions without aid of an artificial UV light....means this is not all that well understood. I have shown you pictures and you should see things glowing, reflecting UV light, something science says is invisible to you. We can easily see UV light, we just have to have all the other sources of light back off a little- is all.

This means that all of us should be interested in this stuff, because it is in lots of stuff and it is natural, and we see it even if we don’t notice it, and it has been around a really long time and if the Moon can have an effect on fish, this can have an effect on fish, and I intend to exam it further. Again comments can be made, but experiences are what I am most interested in. What do you know ?

This evening we are having some light shower activity. Intermittent sprinkles. Anyways....standing outside everything looks a little different. The trees are definitely of a different appearance than what is seen in full light.

The visible light at this point is being reduced because of all the suspended media it must travel through ( clouds with water vapor ). The visible light is reduced because of the clouds and that is what is allowing the UV light to be noticed. I have seen this affect my entire life but never really considered what was occurring or how it might affect me. I have seen leaves “glow” like this for years, but didn’t understand what was actually happening. What I was actually seeing. What other creatures might be seeing.

If tomorrow I catch my usual six fish, it will not be enough to convince me that UV enhancement either aids or hinders. I just think that being able to see a bait is better than simply hearing or smelling or feeling that bait. That if UV light is causing leaves and objects to glow because clouds are limiting visible light, that that somehow matters when we fish on cloudy days. That if UV can so easily better penetrate through the clouds, filled with water vapor, than visible light, that UV will definitely penetrate deeper into the water when each are of an equal availability. Penetrate better in clear and dirty algae filled waters is what interests me.

Maybe UV sinkers and jigs and lures and such actually work to scare the little devils. What do you know ?
