Lots of neat ideas come out of the bassin’ world every year, usually around ICAST time. It’s always interesting to see what catches on and what doesn’t.
Things like red hooks certainly had a following. Same could be said for the introduction of ‘sexy shad’ colored baits. Then there are things like Gulp, Attraxx and other Bio baits…and how about sound attractionÂ like the Hydrowave units.
I was browsing through the Bass Pro catalog this weekend when the UV spray caught my eye. Been a bit since that was introduced, still in the catalog though. Remember those Tightlines worms?
So I dug through some of my UV research material and came up with a few tidbits to share.
- Â There are three types of ultraviolet radiation: UV-A (315-400nm), UV-B (280-315 nm) and UV-C (200-280 nm), though most of the UV-C radiation is absorbed by stratospheric ozone.
- There is generally a direct correlation between the amount of dissolved organic matter (DOM)Â in the water and how far UV light can penetrate, since fresh DOM has high UVR absorbance.
- Even in very clear freshwater lakes (visibility to 30′), approx. 90% of all irradiance (light attenuation at 320 nm – longer wave UVA) is absorbed in the first 1.5 meters of depth.
- Even early in the season when DOM tends to be low,Â the 1% attenuation depth (the depth at which just 1% of the UV rays remain) is approx. 8′-9′, and gets shallower as the year goes on.
- Research suggests that only the youngest (yearling)Â bass have the ability to utilize UV reception, and that olderÂ bass lose that ability.
So the question today is who has givenÂ UV baits or sprays a try out there, and do you believe they made a difference (good or bad) in your bass fishing? If you haven’t tried them, why not? Do you believe or do you think it’s hype?
