A lot of times most of your plankton/algae is in the top 70ft of water......so yes , the added visual of glow/UV could help at that level.
On an overcast dull day, it would help too.
UV colors work at any depth....UV light penetrates down to 800ft plus.....but the UV reflectivity would be stronger up shallow. Bass fisherman use UV in 10ft of water.
Glow also = white to some extent. So when the glow has expired (glow usually glows greenish unless you have a specific glow color like ,say, blue etc.) the white component will still be visible. So fish can see it pretty good in murky water.
Fluorescent colors do not lose their color as fast as "normal" colors. Which is why the fluorescent green,pink, yellow and red lures work very well at depth compared to non-fluorescent. Adding a UV topcoat to fluorescent colors does not help fluorescents though. (Info is availble on net about that).
At 45 to 65 ft deep in the chuck, most days, there is quite a bit of light down there. But like I said,in the sunny spring/summer that will also be where a lot of plankton/algae is at times.
Yes...I'd fish UV at that depth.........also glow too.......after about 5pm the angle of the sun isn't all that good for penetration and the light falls off a lot faster in saltwater than it does on land. As soon as the sun starts to get at a certian angle, some of the light rays do not penetrate bu tbounce off the water.
After years of research and testing, I'd have to say Seafever is absolutely correct with this response.
With UV products, the closer to the source of UV rays, the brighter the reaction. As depth is expirienced, the quality of UV rays diminishes so, as expected, does the reacionary effect of the UV product. Fortunately, when the sun is high and bright, penetration to great depths is high.
An intresting, yet often overlooked comment was about sun angle and the effect on UV products. Like a bullet shot into water, the greatest result is a straight down shot. The same applies to UV. If you shoot the bullet at water from an angle, you will most likely bounce the projectile off the surface. Any penetration will be shallow.
For glow products, they are most productive in depths and in warmer waters. High quality glows will "burn" longer in cold water, longest in warmer waters. Cheap glow dust will light up quickly and burn down just as quick.
Using glow in shallow water is productive, especially in dark stained areas and in grass fields such as marsh grass. Under kelp beds, little light is offered so, again, you will see the lure better. If using glow in shallows, lots of folks along the Misssissippi Delta choose different tints such as blues, greens, reds and yellows. I think they are onto something. The tint used is directly related to depth, temps, water clarity, seasonal changes, and marsh grass coloration. There is no relation to species targeted. The species is the deciding factor of lure design- not color or glow tint. They have a very good catch rate, something to consider. I have some extremely bright shrimp lures from that area. They were productive there and have proven themselves here for bottom fish. The smaller version works well for bass and trout as well.
I have noticed no one in this area really offers glow tint choices- all light green. This could be a very limiting factor. I've not seen any other tints in Oregon, Washington, BC, or Alberta. Does anyone know why this is? Is this something I need to look at more closely?
