Color is important?This is a serious problem, fishing enthusiasts and fishermen have in exploring the secret for a long time.Some fishermen and fishermen think color choice is crucial, while others say it is not important.Scientifically speaking, there is evidence that both arguments could be right.There is sufficient evidence to show that the environmental conditions suitable for the situation, choose the right color or can improve the chance of attracting fish, but science can also show that in other cases, the color value is limited, but also less important than imagined.
The fish was born more than 450 million years, is very good.For thousands of years, they made many exquisite in Marine environment adaptability adjustment.Living in a world of water is not easy, there is a high degree of environmental opportunities and severe challenges.In water sound, for example, five times faster than in the air, the water better.The ocean is actually a very noisy place.Through good auditory perception, use them in the inner ear and lateral lines to detect prey or avoid enemy, can take advantage of this fish.Also contain unique compounds in water, fish use them to identify other members of its species, in the breeding season comes, find food, detect predators and perform other functions.Fish have formed a remarkable sense of smell, are thought to have one million times better than humans.
However, water for fish and fishermen, for visual and color is a serious challenge.Many of the characteristics of light rapidly changing with water flow and depth.
Attenuation of light?
Human see the light from the sun just receive a fraction of the total electromagnetic radiation, which we see as visible light spectrum.Within the visible spectrum of the real color is decided by the wavelength of light: the longer wavelength as the red and orange;Shorter wavelengths are green, blue and purple.However, you can see many fish we don't have a color, including ultraviolet light.Uv transmission distance in water than most of us think too much.
When the light into the waters, the strength drops rapidly, color changes.These changes are called attenuation.Decay is the result of two processes: scattering and absorption.Light scattering by particles suspended in the water or other small objects - caused by particle, the more the more scattering.Scattering of light in the water and the effect of smoke or fog in the atmosphere.Because river input, coastal water, there are usually more suspended material, from the bottom of the mixing material, and increase the plankton.Because of this greater amounts of suspended matter and light often infiltrate into the depth of the smaller.In a relatively clear coastal waters, the light penetrated deeper depth.
Light absorption is caused by several kinds of substances, such as light is converted to heat, or used for chemical reactions such as photosynthesis.Fishing is the most important aspect of the influence of the optical absorption of the water itself.For different wavelengths of light, absorption is different;In other words, the absorbed all sorts of color is different.Longer wavelengths, such as red and orange, is absorbed quickly, and penetrate the short wavelength light blue and purple is much depth.
Absorption also limits the light into the waters of the distance.About three meters (10 feet), about 60% of total light (the sun or moon), almost all of the red light will be absorbed.At 10 meters (about 33 feet), about 85% of the total light and all the red, orange and yellow light is absorbed.This will seriously affect the angler bait effect.In the depth of three meters, red into ice show for gray, with the increase of depth, it will eventually become black.With the increase of depth, when all the other colors are absorbed, the light of the dark blue now, in the end.
The absorption of color or filtering also work in horizontal direction.So once again, a red flight seems to be only a few feet away from fish grey.Similarly, other color also changes with distance.To see color, it must be the same color of the light hitting, and reflection on the direction of the fish.Attenuation or filtered) if the water is a kind of color, then the color will be displayed as grey or black.And because of UV line penetration depth is larger, the fluorescence under ultraviolet (UV) radiation, is one of the rich underwater environment and its important part.
What is the best color light to attract fish?
Scientists don't really know what fish to see, in other words, what image to their brains.Most of the research on fish vision is through the eyes of different parts of the physical or chemical examination, or by determining how the fishes of the laboratory response to various images or stimulus.Through different species may have a different visual ability and laboratory results may not represent the sea, lakes or rivers of events in the real world, visual ability of fish to make highly consistent and definite conclusion is not scientific.
Research on physics of eye and retina suggests that most people can get a clear focus on image, detect movement, and has a good ability of contrast detection.And have plenty of experimental results show that before the fish can identify the color, need the light of the lowest level.With the deepening of the research, different fish has like a particular color.
