Colour of lines...What really?

[robd]

Yes you’re right, Red is the first colour to ‘disappear’ under water and Blue being the last at a greater depth, and as you say they appear black. Food for thought for those that like to colour bait in deep or coloured water !!

Fish must be well used to brushing past/into things they can see but if I was a fish I'd be spooked by bumping into something I couldn't see, Fluorocarbon perhaps.

All,

 

The "early" problems with flurocarbon was the light transmission. I'm not sure now or ever what carp "see" with flurocarbon. They won't talk. The problem stemmed from a test you can easily perform yourself.

 

Take a length of flurocarbon line - say 2 meters - tape one end to a flashlight ( I believe maybe you would say a torch). Cover the lense with black tape so not light escapes. Now in a room with subdued light take the other end and shine it on the wall. You will see the tip of the flurocarbon line is a transmission line for the light. Equally, it is not as bright as the flashlight because small amounts leak along the path.

Fish (carp) see the light. That was the conclusion for statistically significant "avoidance" not experience by other line materials.

 

As I have said, this was 1992 and I'm sure there have been technical improvements in fishing line. Fluorocarbon was always a good leader material since both ends were submerged.

 

A further problem (with carp and other fishes I'm sure) is that we are not (weren't) real sure how much into the UV light spectrum they can see. It is much further than the visible light spectrum than we see - that much is known.

 

Gulp! I hope Gozzer doesn't still read AN (actually I hope he does and is doing fine). Line size did not influance number of contacts.
