UV light is a high frequency energy spectrum that can’t be seen by the human eye (or any mammals that we know of) but can be detected by many species of birds, bugs and fish. They can have UV patterns on them to help distinguish between species and individuals – like freckles of finger prints, etc. It’s found on shrimp, plankton and many types of underwater prey. Making them easier to spot by those hungry beasts we want on the end of our line. UV light is given off naturally by the sun, it can travel deeper in water than the human visible rainbow, up to 750 feet or more. Some scientists claim that it can be seen even as deep as 2,500 feet. In comparison, the red spectrum of light can only be seen by fish up to 30 feet and that’s in ideal conditions! It can disappear in as little as 2 feet. Then we lose yellow/green colours and lastly blues, up to about 40 feet. It may not be a bad idea to spring for those red hooks after all.
