I've often wondered if there was a color that the human eye could see that the shrimp eye couldn't. If so, it might be a good color shrimp light. I'm thinking colors on the extreme of the spectrum would be likely candidates, red or purple. Red might pose some problems in deeper water as the water absorbs that wavelength pretty quickly though.

The matis shrimp eye structure is a compund eye, similar to our shrimp. Would take some more research into this subjec, but the mantis is a good starting point. Having said that, it's the human eye that is the real limitation to catching shrimp. Can't dip what you can't see. "Humans see three colors that, combined, allow us to enjoy the visible light spectrum. The mantis shrimp sees 12 colors, ranging into the near-ultraviolet to infrared parts of the spectrum. The creature can also distinguish different forms of polarized light. "

I have found that by wearing a red led cap light, you get the eye reflection back without spooking shrimp, or causing glare.

The colors would appear to be yellow/green to yellow. Light travels through water the farthest in a cobalt blue, whence the color of the deep oceans with no pollution or life forms present will be cobalt blue. It would not likely make a good color for a shrimp light as your eye would not Pick it up as efficiently as a shift toward yellow. The compromise in the shift would be in the lower frequency of yellow or pale green. Frankk

Posts: 599 04/06/10 12:03 AM SPONSOR Resident Engineer LED GREENIE	Both of you got it right. In terms of humans tho, green is the color the human eye is most sensitive to according toThe C.I.E. Chromaticity diagrams. The most sensitive response is in the 520 nanometer region, which also corresponds to the LED light of the LED Greenie. Green fllouro light is a mix of phosphors and has a significantly wider wavelength spread than the LED light.. Did you ever notice interstate signs and how the green stands out at night? Takes less light for humans to see that light. There are several other reasons for using green , but it's late and the topic might get boring.
