Cajun Line Red Lightnin' Mono, new leader idea?
 
As a marine scientist and avid fisherman, I subscribe to quite a few publications, one of them being Salt Water Sportsman. In the most recent issue, I saw an ad for a monofilament that's colored red. The manufacturer claims that the red coloration makes the line become virtually invisible at depth, due to the light filtering affect that seawater has, causing red wavelengths to be absorbed and refracted within the first few feet of the sea surface. Intrigued, I went to their website and found a short Quicktime video showing a pair of identical lures being waved around in a tank full of largemouth bass and catfish; one lure is tied up to "other brand" mono, while the other is tied to this red mono. From the video, I must say it's hard to see the red line. I started thinking about how this mono might be incorporated into a leader, or even a red sinking fly line for offshore fishing.
There are numerous aspects to light attenuation in seawater; one reason that many deepwater and nocturnal species have evolved to exhibit red coloration is that, at depth over 3 meters or so, no red light (emitted by the Sun) exists, and therefore these animals appear to be black or a similar dark color. At depths of 150 M or more, no light, other than that produced by bioluminescence, exists at all, which means that the coloration of the fish and invertebrates becomes largely irrelevant. This is why many of them are just plain silver, black, colorless, or off-white (some of these invertebrates are red or deep purple, also); they appear literally invisible unless illuminated with some light source that contains the wavelengths present in their tissue coloration. Red line, assuming that it contains no other pigments, should behave similarly and become quite invisible. I wonder what the comparison with fluorocarbon will end up being?
I'm going to order a few spools of this line, to see what the results are; at $5 per 300 yds., what can it hurt? It may very well be another advantage for those of us that routinely probe the depths with a fly looking for the next finned monster to strike.
Has anyone out there used this line, and what are your thoughts on the application to fly fishing?

Use as a strike indicator?
 
Tied as a butt section on a leader, it would probably make a good strike indicator for nymphing, et. al. Sounds interesting - I'll keep an eye out for it.

flyfisha1 -

Yes you're probably thinking I am going to remind you of the direct link / non-sponsor policy. Well I just did.

But on the topic of red filtering, did you ever bite the bullet on the $5 and try it?

Got my curiosity...

Juro - Roger that, have already sent the e-mail out, will forward a copy. Yup, I bought a few spools to give it a shot, but have yet to actually get out to open water for a test. I'm hoping to get back down to Florida in a few weeks to wet a line, and will post my findings then. I still think that a red sinking line would be effective, all of this in perspective.

I read that same article. Here's a thought: wouldn't it stand to reason the red would hold together better over a lighter colored background, like a sand flat, or even highly lighted 'green' water better than in darker or more mixed camouflage conditions -

I know the color disappears; I just wonder where, given the light values over backgrounds like those mentioned. Go lay a length out on a flat for us, Chris - hope you haul it back with a bone on the other end! :smokin:

You bring up a good point. Any water that is lacking in red wavelengths should serve to camoflage the line to an extent. High-turbidity, murky, green water would seem ideal, since the red light would be scattered at a very low depth. This is starting to make me think that rivers discolored by rainfall and algae blooms, in addition to Northeastern shallow coastal areas with high turbidity, might hold some promise for red line. If the red line was indeed less visible to the fish, yet highly visible to the angler, that would be quite a new product. If we could only convince one of the clear line manufacturers to make a clear/red intermediate line for trial purposes... I think there are plenty of willing field-testers on the forum! Any suggestions?

Chris-

With your last point in mind, red line almost becomes a moot issue with manufacturers (CORTLAND???) making camouflage colored mono and fly line.

Regardless, if i see it on a shelf around here, I'm gonna grab a spool and give it a go.

Yes, clear/camo line is great for low visibility to fish, but for those anglers wanting a line highly visible to them but not so easily spotted by the fish, the red line may be an option. Give it a shot; I haven't had a chance to get to the water since I got the line, but will certainly post my report when I do get an opportunity to fish it.
