Falling into the category of "Pure BS . . . unless you've seen it first hand", one of the guides in Yakutat, Aaron Shook (www.hobofishing.com
) has videoed quite a few sockeye eating red Gami #4's fluttering around at eye level. The technique isn't quite bamboo rods and silk lines, however. Take any old baitcasting or spinning rig with a mono leader. Thread the 8lb UG on a hollow core 1 oz lead weight, then a red bead to keep the sinker off the knot/hook, then knot that Gami #4 on.
Here's the tricky bit: in crystal clear water, anchor in 4-8' over a bunch of socks. Usually they'll keg up downstream of a log jam. Poke the nose of the boat over the logs, drop the pick upstream and then . . . . (Again you have to see this . . . .
) free spool to the bottom. Wait for the fish to un-spook and begin milling under the boat. Snap the rod up about 18"-24". The bead and hook will CLICK into the bottom of the sinker. Drop the rod and about a foot of line floats free and the red hook flutters down. Every 20 snaps
a sockeye veers out of the pod and quick as lightning smacks that bare hook. It's then a rodeo as you horse the fish in on 7' feet of line, trying not to spook all the other socks downstream 100 yards. If you can get it into the net in 30 seconds or so, then the fish will settle down a few minutes later and return to their previous staging area.
After 15 minutes, the wonder has worn off. You've landed a few fish and lost an equal number, and you're wondering why you are doing this at all because it's quite tedious. (Except for the bit where you prove to yourself that the fish aren't being snagged or lined, and are actually swimming out of their pattern to eat.)
Once you see this rig in action, you can certainly believe that "somethings" fluttering, swinging or dead drifting at eye level can entice a sockeye to bite. On my flossing fly rig I had fair hooked socks on red, silver, blue and green Gamis . . . maybe 10% of the total hookups with 90% lined.
I doubt it's the color. I think it's a size/ movement/ peripheral vision triggering action that induces the take. But that's SWAG.
Needless to say, a little of this goes a long way.
