The right set of lights can improve one’s chances of catching big fish. But unlike hunting, red lights are rarely used by professional anglers in the water. Instead, white and green are heavily utilized, in favor of their ability to attract zooplankton and small fish close to the boat. If lured properly, underwater lighting entice large fish to feed around the target area.
Why White and Green?
Plankton are naturally drawn to white and green light colors, due to their urge to reproduce under such conditions. Out of the two light colors, green is preferred because it can penetrate the water deeper than white bands. At lower depths, green also appears clearer. This reduces the gap between predatory fish – usually lurking much deeper underwater – and small baitfish. Other lights, such as blue, are unattractive to plankton in fresh water. By comparison, blue light is noticeably effective in saltwater.
When catching large fish, one must cast the line below the group of zooplankton near the surface. Predatory fish are known to observe prey from a distance before striking. Even with green light, large fish rarely swim very close to the surface, as the creatures are not attracted to the green light – only to plankton and baitfish.
Types of Boat Lights for Fishing
There are several types of boat lights for fishing. Traditionally, floating luminaries were extremely popular options for anglers. However, the lights attracted insects around the surface of the target area. To prevent luring insects close to the boat, individuals began using submersible LED fishing lights.
For reliability in the water, the luminaries are typically waterproof, low voltage and battery powered for portability. A small weight attached to the unit pushes the underwater lighting below the surface, at roughly 2-3 feet. It is common practice to install a few lights around the vessel, as opposed to using one, powerful luminary pointed directly down at the water.
