This is a trusty method to tie a braided wire/knottable wire setup, which is especially recommended for Tanzanian tigerfish (Jimmy Eagleton and I also used it with great success to catch our local snoek more recently). These tigers grow surprisingly big for the ‘smallish’ rivers they live in and due to the limited space and many fallen trees, hooked fish are easily lost. However, this trace setup can take a lot of pressure; a drift comes to mind where an estimated 23 lb tigerfish sipped my baitfish pattern right next to the boat and also right on top of two big fallen trees, I applied as much pressure as possible from the hookset onward, forcing the tigerfish to swim into the open, main channel of the river and the brand new fly line parted, and to my surprise not this knottable trace setup (which I would’ve considered the weakest link).
Firstly, it is important to note that specifically 35 lb American Fishing Wire (AFW) Surflon Micro Ultra 19 strand is recommended for Tanzanian tigerfish. I am sure that anglers would get fairly good results with lighter braided wire [like 26 lb American Fishing Wire (AFW) Surflon Micro Ultra 19 strand or 20 lb Rio Wire Bite] and these knots for Zambezi tigerfish and other smaller tigerfish species, like Hydrocynus forskahlii.
The wire will be joined to the monofilament tippet with a slightly modified surgeon’s knot:
The wire will be tied to the fly with a slightly modified Lefty’s loop knot:
