The 2st topic is “AZEERO FUNE HARISU SV-Ⅰ”.

The pink color of SV-Ⅰcalled magical pink is difficult to see for fish.
We proved scientifically that fish is hard to catch the wavelength of the pink color.
We created this line after the actual fishing test many times. (Patent NO.4768937)

The magical pink is especially effective for Seabream and Red snapper.
We can recommend to use SV-Ⅰ as s shock leader for Tairaba, Jigging and black snapper fishing.
We would like you to use the line if you want to get more fish than other angler in high pressure situation.

The pink lines restrain light reflections more than clear lines.
Futhermore, wavelength of pink or closer to red is harder to reach than wavelengths of other colors into the sea.
Therefore, Fish is hard to recognize the magical pink color.
That is, fish feel less wariness and it helps that hit rates become higher.

FYI,
Japanese squid fisherman keep using SV-Ⅰ all the time as s secret line.
The line is soft fluorocarbon.
Due to the line quality, it is possible to make a beautiful knot and it dose not bother the lure action.

【Black snapper and Red snapper are a color-blindness】
We asked our researcher to research if the fish really a color-blindness.
The researching method is the observation of the fish reaction when a light stimulus affect retine of the fish.
As a result, the retines of black snapper and red snapper did not always react to several light stimulus.
That is to say, the answer is that they are color-blindness or very likely.

【Nomally any kinds of fish react sensitively to a blue-green color】
Even fish which is a color-blindness such as black snapper react to wavelength of 530nm.
What color is the wavelength of 530nm? That is blue-green.

The many blue-green color exist the sea where fish inhabits.
Fish eyes have evolved to respond to colors with wavelengths changed slightly from the blue-green color.
The reason of the evolution is that it is easy to find baits having the color contrast in the world of blue-green color.

Coastal water have many wavelengths that are a little bit longer than the wavelength of blue-green.
The place affected by fresh water are rich in longer wavelengths of red color.

The fish is hard to notice the red colors especially in coastal water where is rich in
wavelengths of red color and in offshore with big rocks where mix coastal water and ocean tide.

Thank you very much for reading the topic through to the end.
